MegaCrimp® couplings feature exclusive TuffCoat® plating
MegaCrimp® couplings feature exclusive TuffCoat® plating. TuffCoat® gives MegaCrimp® couplings five 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.
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. 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.
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 "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.
These versatile couplings can crimp a wide range of medium-pressure hoses, which simplifies inventory needs. And they're fast and easy to crimp, making them ideal for field installation.
The majority of hydraulic hose failures occur at the couplings, due to blow-offs or leaks. With hose, couplings and assembly equipment from one manufacturer, all designed as an integrated solution, the greatest operator safety is ensured whilst plant downtime is reduced. Gates MegaSys® complies with the Guideline for Fluid Power System Safety at Mines, MDG41.
One of the most common causes of hydraulic leaks is a cracked coupling nut or seat due to over-torquing.
MegaCrimp® Couplings with Full-Torque Nut™
Gates has engineered a solution - Full-Torque Nut™ technology now available on Gates MegaCrimp® couplings (wire-braid hoses) and GlobalSpiral™ couplings (spiral-wire hoses).
Full-Torque Nut™ couplings are stronger and more durable than traditional staked-nut fittings. A large holding shoulder evenly distributes stress forces at the nut for higher resistance against cracking, even when inadvertently over-torqued.
Increase productivity and equipment uptime, on the assembly line or in the field, by eliminating damaged couplings and unsightly leaks from too much torque.
