Product Description

The 80x5.6 FPM O-Ring is engineered for sealing systems that require excellent chemical stability and long-term performance under severe operating conditions. Its circular cross-section creates a reliable seal when compressed between mating components, preventing leakage of liquids and gases while maintaining operational integrity.

Manufactured from FKM (FPM) fluoroelastomer, this sealing ring provides significantly higher resistance to elevated temperatures and aggressive media than standard NBR compounds. It maintains its elasticity over a wide temperature range and performs reliably in systems exposed to mineral oils, synthetic lubricants, fuels and numerous industrial chemicals.

Because of its outstanding durability, the FPM O-ring is widely used in OEM production, industrial maintenance (MRO), hydraulic equipment, pneumatic systems, pumps, valves, compressors and automotive assemblies.
