The SAFETY G-Coupler is a premium high-pressure grease coupler designed to end the frustration of leaking connectors and wasted grease. Engineered for professionals who demand the best, this coupler features a unique four-hardened-jaw locking mechanism. Once you clip it onto a grease nipple, it stays locked tight, allowing for hands-free operation even at extreme pressures up to 10,000 PSI (690 Bar).
This device is specifically called a Safety Coupler because of its integrated trigger release system. In traditional couplers, high back-pressure can cause the connector to “stick” to the nipple, forcing the user to yank it off, which often leads to broken grease nipples or sudden hand injuries. With the Safety G-Coupler, you simply press the thumb lever to instantly equalize the internal pressure and safely disconnect. This mechanism protects the equipment from damage and ensures the operator’s hands remain safe from slips and sudden movements.
Built with a standard 1/8″ BSP female thread, the G-Coupler is compatible with all manual, battery-powered, or pneumatic grease guns. With its slim 15mm diameter, it can reach into tight spaces that other locking couplers cannot. It is the most reliable, durable, and user-friendly upgrade you can give your lubrication equipment.
