Metal Work Food Grade Male Stud 4MM to M5

Brass parts are chemically treated with phosphorus nickel-plating according to the NSF/ANSI 51 standard of the food programme. The seals are made of FDA-approved FKM/FPM. Fittings contain no technopolymer, solving the problem of incompatibility with detergents and other chemicals. The fittings can be used up to +150°C, making them suitable for high temperature applications other industries. The threads are cylindrical and under-head o-rings provide a pneumatic seal. This avoids the need for sealants (e.g. Teflon) which could release solid fragments during screwing and unscrewing that would contaminate the environment or the fluid. Our fittings can be screwed and unscrewed any number of times and still remain clean and pneumatically sealed. This choice of materials and treatments make these fittings suitable for use in the chemical, pharmaceutical, medical and electronics industry. Threaded ports: M5, G1/8", G1/4", G3/8", G1/2". Pipe diameter: 4, 6, 8 and 10mm. Recommended pipe: Rilsan PA 11, nylon 6, polyamide 12, polypropylene. Under-head O-ring can be screwed and unscrewed any number of times; no fragments of Teflon or sealant will contaminate the fluid. Corrosion proof: chemical nickel-plating + FKM/FPM, compatible with numerous substances. No plastic parts, so no risk of incompatibility.
