Is the Polypropylene TRI-CLAMP Tip with BSP Male Thread, 3C Series compatible with EPDM, FKM, Gylon® and PTFE gaskets for hygienic applications?

Yes. The Polypropylene TRI-CLAMP Tip with BSP Male Thread, 3C Series is compatible with EPDM, FKM, Gylon® and PTFE gaskets for hygienic applications. The fitting is supplied without a gasket so users can choose the appropriate seal material—EPDM, FKM, Gylon® or PTFE—each offering distinct chemical and temperature resistances to meet hygienic and industry-standard requirements. The product’s compliance with DIN 32676, ISO 2852 and BS 4825, its polypropylene/PVDF construction and up to 6 bar working pressure make it suitable for laboratory, medical, pharmaceutical, chemical and food industry applications when paired with the correct gasket.

Can the Polypropylene TRI-CLAMP Tip with BSP Male Thread, 3C Series be autoclaved repeatedly without degrading its sealing performance or BSP thread integrity?

Polypropylene TRI-CLAMP Tip with BSP Male Thread, 3C Series: Polypropylene and PVDF parts generally tolerate autoclaving temperatures (121°C) differently. PVDF has excellent thermal stability and typically withstands repeated autoclave cycles with minimal dimensional or mechanical degradation; polypropylene is more sensitive to repeated exposure to high temperature and steam, which over time can cause some creep, loss of mechanical strength, or slight distortion that may affect sealing surfaces and thread fit. The product description states construction from high-quality polypropylene or PVDF but does not guarantee autoclave resistance or specify cycle limits. Sealing performance also depends on the gasket material chosen (EPDM, FKM, Gylon®, PTFE): PTFE and some FKM grades are more autoclave-tolerant; EPDM can handle steam but may age faster; Gylon® and specific formulations vary. Conclusion: If your item is the PVDF version, it is likely suitable for repeated autoclaving with minimal impact on sealing and BSP thread integrity. If it is the polypropylene version, repeated autoclaving may degrade sealing performance and thread fit over time. For a definitive answer, consult the manufacturer for validated autoclave cycle limits and material certificates, and validate with in‑house autoclave testing using your chosen gasket.
