A gasket may look small, but it is a critical safety component. Its failure can lead to leakage, downtime, and significant operational risk. Mitigating these risks requires manufacturers to rely on a partner with proven capabilities to reduce technical, logistical, and material uncertainty across the whole lifecycle of a sealing solution.
For more than 80 years, TT Gaskets has helped major industrial companies worldwide solve their most demanding sealing challenges, from material compatibility and leakage issues to new designs and emerging clean-energy applications. The engineering process is supported by in-house design and validation testing, with products delivered to more than fifty countries.
Today, as the largest gasket manufacturer in the Nordics and a globally trusted expert in sealing technologies, TT Gaskets provides more than manufacturing capacity; it provides true risk reduction for customers whose operations demand absolute reliability and zero unplanned downtime.
Design support that reduces risk and cost
Customers turn to TT Gaskets when a seal fails, when developing a new application, when operating media changes, or when entirely new sealing concepts are needed. In each of these cases, the most critical requirement is the same: the gasket must seal reliably under operating conditions and be available quickly when needed.
“TT Gaskets provides complete sealing solutions from material selection to documentation and rapid delivery. We manufacture gaskets, metal components, and insulation parts; we design full sealing systems; and we support our customers with all required services, from PPAP documentation to one-day fast-track deliveries.” Petri Lehtinen, Head of Global Sales & Marketing at TT Gaskets,explains.
TT Gaskets is not just a trusted manufacturer but also a design partner. The company can provide several solutions thanks to versatile design concepts that the internal design board continuously explores and reviews. The board’s expertise includes gasket behaviour under chemical exposure, during temperature cycling and mechanical load or under any other extreme conditions.
Design completed with the right materials
By combining TT Gaskets’ variety of materials and brands with the company’s strong technical knowledge, customers get not just the main material but also good alternatives that help lower supply chain and geopolitical risks.
Material selection is not a minor detail; it is a key part of risk management. The right material affects durability, chemical compatibility, temperature resistance, and the safety of the entire process. The incorrect material leads to failure; the right material enables years of trouble-free operation!
As Petri Lehtinen explains, material selection is never trivial: “Designers want ‘belt and suspenders’. TT Gaskets provides the unique capability to design optimal sealing solutions and choose the best materials for customers’ applications. The chemistry changes, and the gasket must change with it.”
With approximately 3,500 raw materials in stock and access to a wide range of material brands, TT Gaskets is able to match the optimal material to each application. This is why customers involve the TT Gaskets team early in the design phase. This deep technical expertise minimises uncertainties for customers long before the gasket reaches the production stage. The company’s experts understand the pitfalls of geometries and materials and know how to avoid them before they become problems.
Agility with rapid modelling, testing, and prototyping
In industrial development projects, time is often the most valuable resource. Design upgrades, new aggressive media, redesigned flanges, and other parts all require rapid validation. Delays in gasket design can delay the entire project. TT Gaskets’ development approach effectively prevents such delays.
The company either designs the geometry from scratch or refines the customer’s drawing. The first prototype is produced quickly, and key mechanical characteristics, such as compressibility and recovery, are verified in-house in accordance with customer requirements. Depending on the application, additional evaluations, including sealability, temperature resistance, chemical resistance and leakage rate, may be incorporated at an early stage of the development process.
Unlike many competitors that require €5,000–10,000 in tooling before producing the first sample, TT Gaskets can create prototypes using simple, economical methods. This keeps entry costs low, enables early testing, and reduces the final risk of each project phase.
Efficiency and sustainability in deliveries
Long-term investment in machinery, processes and software has created a manufacturing platform that delivers both high quality and strong capacity. This allows production to scale smoothly as customer volumes grow, without the typical concerns that come with increasing output.
Petri Lehtinen summarises it clearly: “Our production stands out because of its consistently high quality and excellent capacity. Our owners have invested in equipment, processes, and software year after year. Because of this, we could increase our output by 50% without any new investment. Our production is not a bottleneck!”
This level of capacity gives customers two clear advantages. TT Gaskets can support anything from small prototype batches of single units to mass production runs of millions of pieces. Multiple manufacturing methods allow the company to manage small series, large series, urgent needs, and fluctuating demand without compromising quality or delivery reliability.
TT Gaskets has the capacity to deliver reliably throughout the entire project lifecycle. The lifespan of industrial projects is often 6–15 years, and the supplier must support the customer both during initial production as well as long-term service needs.
To support customers globally, the company has developed logistics capabilities that serve more than fifty countries, ensuring reliable and well-coordinated deliveries across regions timely and accurately. To complete the requirements of the domestic market, the company also provides shutdown services for maintenance customers in Finland.
TT Gaskets has also made long-term commitments to sustainability in order to help customers reduce the environmental footprint of their supply chains. The company currently works actively to reduce transport costs and emissions by using lightweight cardboard pallets instead of wooden ones. The TTG Green Delivery concept has been launched to avoid plastic entirely in shipping materials, and only non-plastic materials such as paper tape, paper bags and cardboard are used. These efforts reflect the company’s belief that responsible operations are both achievable and essential!

These efforts reflect TT Gaskets’ belief that sustainable operations are both achievable and essential, while helping customers reduce the environmental footprint of their own supply chains.
Example case: Rapid gasket solution and testing in weeks – without expensive tooling
Recently, a global OEM required a new gasket solution due to changes in operating conditions and media. The new application placed demanding requirements on sealing performance, material compatibility, and development speed.
TT Gaskets was involved early in the development phase to support both gasket geometry design and material selection. Through close engineering collaboration, the new gasket design reached completion within just a few weeks. Instead of investing in expensive production tooling, the customer was able to start testing immediately using cost-efficient prototype manufacturing methods, significantly lowering the barrier to early validation.
The prototypes were tested for key performance characteristics, including sealability and material behaviour under real operating conditions. Full technical documentation and test data were then delivered to support the customer’s validation and decision-making process.
After successful testing, the accelerated development approach enabled a smooth transition to production and ensured reliable performance under demanding operating conditions.

How the Use of Servo Electric Die Cutting Presses Can Improve Productivity, Profitability &
Add Sustainability to the Converting Industry
By Greg DeFisher, Owner/CEO, Freeman Schwabe Machinery
Hydraulic die cutting, laminating, and molding presses have been the standard types of presses used in the converting industry for years. Developments in servo electric actuator technology have created sustainable and ‘cleaner’ solutions for material converting.
This advanced technology uses a servo electric actuator system which is ideal for Clean Room™ manufacturing. While ideal for medical device manufacturing, a servo electric die cutting press can also be used in other manufacturing facilities that must avoid material or part contamination.
The servo electric technology can enhance the productivity, safety, and profitability of material converters.
Considerations in Choosing a Servo Electric Die Cutting Press vs. a Hydraulic Die Cutting Press
Using servo electric presses for your die cutting and converting applications has multiple benefits.
Cost Effective
A servo electric die cutting press has a smaller footprint and cuts costly parts (vs. a hydraulic powered system), such as filters, pumps, and valves. Maintenance on servo electric die cut machines is minimal – no refilling or worrying about proper disposal of the hydraulic oil. A servo electric system results in a lower cost of ownership over the life of the press.
Faster Production
The shorter reaction time of a servo electric die cutting machine equals higher cycle rates! A servo electric system has superior precision and control that increases flexibility, part quality, and tool life.
Safe & Environmentally Friendly
Low noise levels – there is only audible noise you will hear from a servo electric die cutting press is when the platen is moving. Comparing this to a hydraulic die cutting system where there is the constant noise of an electric motor.
No use of hazardous fluids – a servo electric die cutting solution can be an environmentally friendly and safer option for manufacturing facilities.
Flexibility
Another major benefit of using a servo electric die cutting system is that you can do many of the same things that a hydraulic die cutting system does – which includes using multiple types of tooling (cutting against steel & kiss-cutting, steel rule, match metal, forged, etc.) and the tooling can be mounted in multiple ways. The feed systems vary and can be designed and tailored to specific applications including cutting on a medical grade PET belt, powered tables, and even robot integration.
Energy Efficiency
Servo electric die cutting presses save you money and help the environment, the benefits add up! Servo electric die cutting machines use 80% less energy used than a hydraulic powered die cutting system. The servo electric die cutting presses provide faster cycle times with superior precision and control that increases flexibility, part quality and tool life.
Servo Electric Die Cutting Press Applications
Servo electric presses can be used to die cut, mold/trim, laminate and emboss all types of materials that are converted for consumer, agricultural and industrial applications.
A servo electric die cutting system is perfect for converting materials such as:
