The Green All Size FKM O-Ring is a premium sealing component engineered for demanding industrial environments where high temperature, fuel resistance, and chemical stability are essential. Manufactured from fluorocarbon rubber (FKM), these O-rings provide exceptional durability and long-term sealing performance under harsh operating conditions.
Unlike standard rubber seals, the Green FKM O-Rings are specifically formulated for resistance against aggressive automotive fuels, industrial lubricants, solvents, and a wide range of chemical media. Their distinctive green color also makes them highly recognizable for identification, quality control, and installation management across manufacturing and maintenance teams.
What Makes Green FKM O-Rings Different?
Unlike traditional NBR or EPDM O-rings, Green FKM O-Rings are engineered with a fluorine-rich polymer structure.
This unique molecular configuration gives them:
The green color is not only aesthetic - it also serves as visual identification for engineers, maintenance teams, and OEM assembly standards.
Performance Characteristics
1. Wide Temperature Operating Range
FKM rubber remains stable from:
-20°C up to +230°C continuously, with short-term peaks at +300°C+
Even longtime exposure to heat does not significantly reduce elasticity.
This makes the Green FKM O-Ring suitable for:
2. Exceptional Chemical and Fuel Resistance
Green FKM O-Rings offer superior resistance to:
Gasoline, diesel & biofuels
Ethanol and high-aromatic fuels
Crude oil & lubricants
Hydraulic fluids
Acids & solvents
Aviation kerosene
Industrial chemical media
Where conventional rubber fails, FKM persists.
3. Superior Compression Set Resistance
Compression set is one of the main reasons sealing systems fail.
Green FKM O-Rings preserve sealing force significantly longer than:
even under:
4. Low Permeability & High Gas Tightness
Ideal for:
FKM barriers are tighter and safer over long maintenance cycles.
O Ring Applications
They provide reliable sealing performance without deformation or leakage.
Typical Applications:
Plumbing systems: Prevent water leakage in joints and pipes.
Machinery & equipment: Used for hydraulic and pneumatic sealing.
Automotive parts: Suitable for engine, fuel, and brake systems.
Home & garden tools: Replacement parts for Bunnings machinery and DIY projects.
