MegaCrimp Couplings

MegaCrimp® Couplings Have a Crimp Seal You Can Count On

MegaCrimp couplings give you a leak-proof seal that’s so innovative, it’s patented.* During testing, it surpassed one million impulse cycles. *U.S. Patent #5267758
MegaCrimp Couplings Feature Exclusive TuffCoat™ Plating
This innovative plating gives our MegaCrimp couplings four times more corrosion resistance than before. That’s 400 hours of red rust corrosion protection when subjected to rigorous SAE-J516 and ASTMP-117 salt-spray conditions. This 500+ percent improvement over the 72-hour SAE standard proves Gates not only raised the bar on corrosion resistance – we’ve set the standard.
Unique “C” Insert Starts Round, Stays Round
During crimping, only the outside shell of a MegaCrimp coupling takes on the shape of the dies. Inside, the “C” insert stays round – like the hose. There’s no “polygon effect.” A comparison of cross-sections with our competitors’ one-piece couplings shows how crimping can distort the hose tube which often contributes to the formation of leak paths, while MegaCrimp couplings remain round.
MegaCrimp Stays Inserted
Once inserted, MegaCrimp stays inserted. It won’t fall out during the crimping process. The advanced design of the MegaCrimp tooth profile also “bites the wire” for maximum coupling retention unlike competitive crimp designs that rely solely on the compression of the rubber.
The Secret: It’s An Inside Job
It’s what’s inside the MegaCrimp coupling that makes it perform so well. The same “C” insert can be used on hoses 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 of MegaCrimp can accommodate many different hose ODs, and on both one and two-wire hoses. An additional bonus: MegaCrimp couplings are a fully qualified EN-performance coupling.
