Grease Fittings
Overview
Grease Fittings are installed onto the seat and stem of valves. Leakage may occur when the sealed part wears off or for other reasons.
The leakage will be sealed temporarily by injecting the grease through the grease fitting to secure time for remedial measures.
Features
- Maximum working pressure: 10,000 psig (690 bar)
- Special design to enable lubricant or sealant to flow around the spring and through the opening on the sides of the retainer smoothly
- All-metal construction, applicable in both high and low temperature environments

FREQUENTLY ASKED QUESTIONS
Grease allows grease to pass in one direction but not the other through one-way check valves. Inside the fitting is a spring-suspended ball check valve. As the grease is pushed into the fitting, pressure is created on the ball check valve of the compression spring, allowing the oil to pass entirely through the fitting. When the grease flow stops, the spring pushes the ball check valve back into place, closing the fitting and preventing grease overflow.
Make sure you have a pushbutton head coupler attached to your grease gun.
- Clean the pushbutton head grease connector for any contamination or debris.
- Slide the knob coupling over the grease coupling to interlock the grease coupling with the coupling.
- Start pumping grease from the grease gun until the desired amount is reached.
Remove grease connector from connector by sliding grease connector over grease connector.
