Caps for symettric coupling

Discover our range of caps for Guillemin-type symmetrical couplings, designed to safely seal unused coupling ends in fluid transfer systems. These symmetrical caps help prevent accidental leaks, protect installations and keep circuits clean when connections are not in use. Fully compatible with standardised symmetrical couplings, they are available in various standard diameters, typically from 20 mm to 100 mm, to fit existing equipment. Manufactured in aluminium, polypropylene or stainless steel, these caps are compliant with the French standard NF E 29572 and are suitable for industrial, agricultural, logistics, chemical and food-grade environments, where secure and reliable sealing is essential.
