FAQ

Q: Are your 21 Series couplings compatible with Legris and Rectus 21 series?
A: Yes. Our 21 Series couplings are designed to be fully interchangeable with Legris, Rectus 21, Rectus 90, and Camozzi series couplings.

Q: What is the maximum pressure rating for the standard 21 Series?
A: The maximum operating pressure is typically 35 bar (507 PSI) for standard models.

Q: What materials are used for the body and seals?
A: The body is commonly nickel-plated brass. Standard seals are NBR (Nitrile Rubber), suitable for general use with air and many fluids within the specified temperature range.

Q: What is the operating temperature range?
A: The standard operating temperature range is -20°C to +100°C with NBR seals.
