A GSD Universal Grease Coupler is a heavy-duty, locking-style accessory designed to provide a secure, leak-free connection between a grease gun and a grease fitting (Zerk). It is specifically engineered to solve common greasing issues such as messy leaks, high-pressure blow-offs, and stuck couplers.
FEATURES:
High-Pressure Capability: Most models are rated for a working pressure of up to10,000 PSI(690 Bar), with some reinforced versions tested up to 12,000 PSI.
6-Jaw Locking Mechanism: Features an upgraded 6-jaw bite lock made of hardened alloy steel that firmly grips the grease nipple.
One-Handed Operation: Equipped with a dual-handle or single-trigger design that allows users to lock and release the coupler with one hand, freeing the other to operate the grease gun.
Leak-Proof Design: Utilizes high-quality sealing gaskets (often TPU or specialized rubber) to ensure grease goes into the joint rather than leaking out the sides.
