Gates MegaCrimp G25170-0406 Hose Coupling, 9/16-18 Crimp x JIC, Steel

MegaCrimp couplings give you a leak-proof seal that's so innovative, it's patented. It's what's inside the MegaCrimp coupling that makes it perform so well, the "C" insert. This "C" insert allows usage with different constructions and wall thicknesses. In addition, the "C" insert ensures an even distribution of crimping forces to form a concentric seal. That simplifies your inventory requirements since one size can accommodate many different hose ODs, on both one and 2-wire hoses. MegaCrimp couplings are a fully-qualified EN-performance coupling.
