Product Description

Polypac Bronze PTFE Seal — Reliable Performance for Demanding Conditions

The Bronze PTFE Seal from Polypac combines the low-friction, chemical-resistant nature of PTFE with bronze filler for improved wear strength and load-bearing ability. Designed for hydraulic systems, oil seals and rotating shafts, this seal gives stable performance in tough environments while extending service life and reducing maintenance.

Key Benefits

High wear resistance: bronze-filled PTFE resists abrasion and maintains shape under pressure.
Low friction: smooth PTFE surface reduces heat and energy loss, improving efficiency.
Chemical and temperature stability: works well with oils, fuels and many chemicals across a wide temperature range.
Long service life: reduced wear and better load distribution mean fewer replacements and lower downtime.
Customizable: available in a wide range of sizes and designs to fit specific equipment needs.

Typical Applications

Ideal for hydraulic cylinders, pumps, compressors, rotary shafts and other industrial equipment where durability and low leakage are critical. Perfect for industries such as construction equipment, manufacturing, marine and energy.

Q&A

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.

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.

What is the difference between a static seal and a dynamic seal?

A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.

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.
