It’s what’s inside the MegaCrimp coupling that makes it perform so well, the “C” insert. This “C” insert allows usage with different hose 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 two-wire braid hoses and select Xpiral hoses. An additional bonus: MegaCrimp couplings are fully qualified for SAE, EN, and ISO performance.
