Our thermoplastic
solutions
Thermoplastic solutions for demanding applications
Our thermoplastic sealing solutions are used when applications require higher temperature resistance, lower friction and/or improved chemical resistance. Polymers are ideal for situations where elastomers cannot withstand the extreme operating conditions, such as high pressure and aggressive environments. With their high mechanical strength and stability under pressure, thermoplastic seals ensure long-term performance in challenging applications.

Scraper Rings for protection
Scraper Rings are made from durable thermoplastic materials that ensure high resistance to chemicals and mechanical stress.
They have been specially developed to handle the demanding conditions in industries, where cleanliness and precision are essential for the operation and performance of the system.
Polymer scraper rings are designed to effectively protect hydraulic and pneumatic systems by removing dirt, dust and other contaminating particles from shafts and piston rods.
By preventing the entry of harmful elements, the scraper rings extend the life of your systems and reduce the risk of wear.
We offer Scraper Rings in a range of standard sizes as well as custom solutions that can be adapted to your specific requirements. Regardless of the application, we supply Scraper Rings that ensure optimal sealing and protection of your equipment.
Haagensen's engineers are ready to guide you, whether you need counsel on standard or custom-made scrapers.

Reliable Guide Rings
For minimal friction
Guide Rings ensure precise control of piston rods, while reducing friction and wear. Our Guide Rings are made from high performance polymer materials such as PEEK and PTFE, making them ideal for demanding applications with high radial loads.
High mechanical strength
Guide Rings´ low coefficient of friction (0.05-0.1 for steel lubrication) and high mechanical strength make them particularly suitable for applications with minimal lubrication and high loads.
Our Guide Rings ensure smooth operation and long life, even under extreme operating conditions.
Back-up rings
For extra safety and protection.
Back-up rings act as an important component that prevents pressure of elastomeric O-rings and support them under demanding operating conditions. They extend the life of your sealing systems and are ideal for applications where high pressures and temperatures are a factor. At the same time, they are designed to ensure an effective seal in everything from hydraulic systems to industrial applications.
Our Back-up Rings are primarily manufactured from strong and durable materials such as pure PTFE, known for its resistance to chemicals and high temperatures. Depending on the application, we also offer variants.
Flat gaskets
High performance in harsh conditions.
Resistant to wear and able to extend the life of the equipment, as well as reduce maintenance costs.
We provide a versatile and reliable solution for sealing tasks where high performance and resistance to chemicals and temperature fluctuations are required.
Our range of polymer-based flat gaskets includes materials such as PTFE, as well as other advanced thermoplastic materials that are particularly suitable for demanding applications.
Polymer gaskets are ideal for industries where tightness and durability are essential, such as chemical production and the process industry. They can be adapted to your specific needs and are supplied both as standard and custom designed – to meet your technical requirements.
We offer a wide range of solutions, from standard flange gaskets to custom polymer gaskets that fit your application precisely.

Encapsulated O-rings
Encapsulated O-rings are an ideal solution when working with chemical resistance and hygiene.
These O-rings are typically with an inner ring of silicone or Viton/FKM surrounded by an outer ring of PTFE, which gives them unique properties for use in e.g. chemical and food industry.
Our encapsulated O-rings come in a wide range of sizes and cross-sections, tailored to your specific needs.
Optimized for extreme conditions
The encapsulated construction combines the flexibility and sealing performance of elastomers with the chemical and temperature advantages of PTFE. This makes them particularly suitable for applications where standard O-rings cannot meet the requirements for sealing or durability. The O-rings are resistant to a wide range of chemicals and can be used at temperatures from -60°C to +205°C.
Encased O-rings are also an excellent choice for food and medical applications as they meet the requirements of both FDA regulations and EU 1935/2004 for food contact materials. They can also be sterilized, which ensures a high standard of hygiene.
Shaft and rod seals
Rotary and reciprocating.
Shaft and rod seals play a critical role in many mechanical systems by preventing leakage, protecting against ingress of dirt and maintaining systems efficiency.
Rotary shaft seals are ideal for applications where the shaft is constantly rotating, such as in motors, gearboxes and pumps.
These seals must withstand high speeds and pressures while ensuring an effective seal.
Our rotary shaft seals are manufactured from advanced polymer materials that provide high resistance to chemicals, temperature fluctuations and wear. They ensure long-term operation and reduce the need for maintenance.
Reciprocating rod seals are typically designed for hydraulic and pneumatic cylinders.
These seals must be able to handle stress and wear while maintaining a tight seal. Our reciprocating shaft seals are made from durable polymers that minimize friction and extend seal life.
