Is the Guillemin Connector Gasket, NBR Rubber compatible with fuel, oil, and common industrial chemicals?

Yes. The Guillemin Connector Gasket, NBR Rubber is compatible with fuels, oils and a wide range of common industrial chemicals. Made from high‑quality NBR (nitrile butadiene rubber), it offers excellent resistance to oils and fuels and good chemical compatibility for typical applications in chemical processing, agriculture and fluid transfer systems. Its durable composition and precise fit provide reliable sealing and reduced leak risk in demanding industrial use.

Can the Guillemin Connector Gasket, NBR Rubber withstand high-temperature sterilization or steam cleaning without losing elasticity or sealing performance?

Guillemin Connector Gasket, NBR Rubber Format is made from NBR (nitrile butadiene rubber), which offers good resistance to oils, fuels and many chemicals and retains elasticity across a moderate temperature range. However, NBR is not highly resistant to prolonged high temperatures or repeated steam sterilization. Typical NBR service temperatures are roughly -30°C to +100°C (short-term up to ~120°C); sustained exposure to high-temperature steam (autoclaving/steam cleaning) can cause hardening, loss of elasticity, shrinkage and reduced sealing performance over time. If your process uses occasional low‑temperature steam or brief contact within the upper end of NBR’s range, the gasket may perform acceptably for limited cycles, but for frequent or high‑temperature sterilization/steam cleaning you should consider materials specifically rated for steam and autoclave use (e.g., EPDM, silicone, or PTFE variants) to ensure long‑term elasticity and sealing reliability.
