FPM O‑Ring 40x3.5 mm - High-Temperature, Chemical-Resistant Fluoroelastomer Seal

FPM O‑Ring 40x3.5 mm - High-Temperature, Chemical-Resistant Fluoroelastomer Seal

The FPM O‑Ring 40x3.5 mm is an industrial-grade sealing solution crafted from fluoroelastomer (FPM/FKM, also Viton®), engineered to withstand extreme environments. With a DIN-compliant size of 40 mm ID x 3.5 mm CS, this O‑Ring offers exceptional performance in temperatures ranging from −20 °C to +200 °C, and remains functional even after short-term exposure to +205 °C.

Constructed to resist oils, fuels, acids, solvents, ozone, and weathering, it ensures reliable sealing in aggressive chemical and thermal conditions. Its low compression set (~11-13%), high tensile strength (≈11 MPa), and excellent elongation (~181%) guarantee long-term integrity.

Ideal for use in automotive engines, fuel systems, chemical processing, hydraulics, HVAC, and industrial machinery, this O‑Ring meets the rigorous demands of professionals and OEMs. It's stocked at simmering.pl and ready for quick 24h dispatch.
