MegaCrimp couplings feature exclusive TuffCoat® plating

This innovative technique 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+% improvement over the 72-hour SAE standard proves Gates not only raised the bar on corrosion resistance – we’ve set the standard.

Images taken at random stages of salt spray testing show that Gates TuffCoat plating significantly outperforms competitive products in protection against red corrosion. Note: the white seen on couplings is salt residue and is not corrosive.

The “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’ onepiece couplings shows how crimping can distort the hose tube which often contributes to the formation of leak paths, while MegaCrimp couplings remain round.

The “polygon effect” is even more dramatic when the couplings are crimped without the hose!

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 shown below on the left “bites the wire” for better coupling retention unlike the competitive crimp shown below on the right that relies 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 assures an even distribution of crimping forces to form a concentric seal. That simplifies your inventory requirements since one size of MegaCrimp coupling 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.

MegaCrimp couplings set a new standard for hydraulic couplings. The unique “C” insert ensures “weep-free” concentric crimping to keep equipment and the environment clean.
