No hands are needed to align or hold the grease coupler in place while greasing.
Grease goes in, not on the machine. Long-lasting rebuildable tool.
COMPATIBLE WITH ALL GREASE GUNS:1/8" NPT(f) thread work with all grease gun types such as pneumatic, manual and battery. Adjustable 3-jaw fits all metric and SAE specification grease nipples.
UPGRADED 2ND GENERATION:Retraction mechanism without stiff spring allows more easier Zerk Fitting alignment, making the grease injection more efficient and convenient, which is perfect for "Blind Spots" operation.
HIGH PRESSURE APPLICATIONS:More Maximum working pressure up to 10,000PSI (690bar). Suitable for high pressure, heavy duty greasing applications.
LEAK-PROFF DESIGN:Extra thickened jaws enhance durability and longevity while the sealing gasket prevents the grease gun locking tip from leaking regardless of pressure build up in the time.
PREMIUM QUALITY:Quality sealing gasket ensures no leak from front or rear at extreme pressure like 12,000 PSI. More easier Zerk Fitting alignment without stiff spring, making the grease injection more efficient and convenient.
