This is a female dry disconnect coupler that attaches to male dry disconnect adapters. Dry disconnect couplers (dry break couplers) help prevent spillage from accidental or normal disconnects using a spring loaded sealing device, minimizing product loss and operator exposure.
This coupler has a 4″ female dry disconnect coupler on one side and a 3″ female NPT on the other.
The coupler uses Viton (Fluorocarbon FKM) rubber seals, which has both a high temperature resistance and a high chemical resistance. Viton seals are a popular choice in automotive, chemical processing, oil & gas, heavy duty machinery, and aerospace industries.
