Polypac BRT Style PTFE Seal — High-Performance PTFE Seals

BRT Style PTFE Seal by Polypac — Reliable Low-Friction Sealing

Exceptional Material Options for Demanding Applications

Polypac's BRT Style PTFE Seal is engineered from High Quality filled PTFE compounds — including bronze-filled, carbon-filled, graphite PTFE, MoS₂-filled, and glass-filled PTFE — to deliver excellent wear resistance, low friction, and broad chemical compatibility. These material choices let you specify the optimal balance of hardness, thermal stability, and lubricity for hydraulic cylinders, rotary shafts, and reciprocating systems.

Precision Manufacturing and Advanced Testing

With a 10,000+ m² facility and 8,000 m² production area, Polypac leverages advanced production and testing equipment to maintain tight tolerances and consistent surface finishes essential for BRT Style PTFE Seal performance. Every seal undergoes dimensional inspection and performance validation to ensure long service life under high pressure and temperature cycles.

Custom Solutions for Special Working Conditions

Founded in 2008, Polypac specializes in customized sealing solutions. Beyond standard BRT Style PTFE Seal geometries, we offer tailor-made seals and assembly-ready components to meet unique OEM requirements and extreme environments. Our R&D partnerships with leading universities enable rapid material development and problem-solving for harsh media, abrasive wear, and vacuum or cryogenic applications.

Complete Sealing Portfolio and O-ring Compatibility

Polypac complements BRT Style PTFE Seals with a wide range of O-rings and rubber rings in NBR, FKM, silicone, EPDM, and FFKM, enabling integrated sealing systems that combine PTFE’s low friction with elastomeric adaptability. This hybrid approach improves sealing reliability across dynamic interfaces and facilitates installation in confined housings.

FAQ:

How do I choose the right material for my sealing application?

Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.

What does "AS568" mean?

AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.

Can I reuse a seal?

We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.

How important is surface finish on the metal parts that contact the seal?

Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
