Is the BSP Male Threaded Coupling with Smooth Tail and Lock for Shell Clamp, Type VSL available with E-CTFE or CF‑E‑CTFE lining for highly aggressive chemicals?

Yes. The BSP Male Threaded Coupling with Smooth Tail and Lock for Shell Clamp, Type VSL is available with E-CTFE lining and with conductive CF‑E‑CTFE lining (R < 10^6 Ω) when supplied in AISI 316 stainless steel, providing maximum resistance and safety for highly aggressive chemicals.

Can the BSP Male Threaded Coupling with Smooth Tail and Lock for Shell Clamp, Type VSL be used at temperatures down to -20°C and up to +65°C while maintaining sealing integrity?

Yes. The BSP Male Threaded Coupling with Smooth Tail and Lock for Shell Clamp, Type VSL can be used at temperatures from −20°C to +65°C while maintaining sealing integrity. The product is designed to operate reliably within that temperature range in compliance with EN‑14420 standards. Its flat face sealing system and material options (brass, AISI 316 stainless steel, galvanized steel, aluminum, polypropylene) support leak‑free connections under the specified temperature conditions; note the reduced working pressures for aluminum (16 bar) and polypropylene (6 bar). For highly aggressive chemicals, choose AISI 316 with E‑CTFE or conductive CF‑E‑CTFE lining for enhanced chemical resistance and safety.
