Materials & Applications

Polypac Manufacturing Equipment Seal is available in a wide selection of materials to match temperature, pressure, and chemical needs. Options include bronze-, carbon-, graphite-, MoS₂-, and glass-filled PTFE for low friction and wear resistance. For elastomer seals, we offer NBR, FKM, silicone, EPDM, and high-performance FFKM. Typical applications include hydraulic cylinders, pumps, valves, heavy machinery, and oil-processing equipment.

Custom Solutions & Quality

We combine advanced production and testing systems with skilled engineers to customize seal geometry, hardness, and compound. Every seal undergoes rigorous inspection to meet durability and leakage standards. Polypac focuses on practical benefits: longer service intervals, fewer failures, and lower maintenance costs.

Question you may concern

Why did my O-ring fail prematurely?

Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.

What is the difference between NBR and FKM materials?

NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F). FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.

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.
