C500H heavy-duty wing nut couplings are found in oilfield and mining applications where high pressure, shockload, or external abuse makes other couplings unsuitable.
These robust, zinc-plated carbon steel couplings are rated to 5000 psi, allow for bi-directional flow, and come standard with buna-N (Nitrile) seals.
The thread-to connect design eliminates brinelling and the cast steel heavy-duty sleeve features an inspection hole allowing the user to ensure a complete connection.
C500H couplings comply with Det Norske Verita North Sea standards.
