One?way check valve
Grease zerk fittings work by acting as aone?way check valvethat allows grease to pass through one way,but not the other. Inside the fitting is a ball check suspended by a spring. As grease is pushed into the fitting,pressure is created against the ball check that compresses the spring allowing grease to pass completely through the fitting.

How do grease fittings work?
Grease zerk fittings work by acting as a one?way check valve that allows grease to pass through one way, but not the other. Inside the fitting is a ball check suspended by a spring. As grease is pushed into the fitting, pressure is created against the ball check that compresses the spring allowing grease to pass completely through the fitting. When grease flow stops, the spring pushes the ball check back to its original position, closing the fitting and preventing grease to escape.

What is grease packed around wheel bearings?
Thick bearing grease is packed all around the wheel bearings every time they’re replaced or even when they’re removed for wheel hub or axle service. Grease caps protect the bearing grease from contamination and also hold the grease that surrounds the wheel bearings in place.
What are grease caps used for?
Grease caps are the small, round, metal covers you see at the very center of a wheel. Sometimes they’re called dust caps, but for clarity, we’ll call them grease caps from this point forward. Grease caps protect your wheel bearings from the dirt, dust, sand, water, salt and road grime that can (and will) destroy bearings. Without grease caps, your wheel bearings simply wouldn’t survive for very long out on the road.
Why are bearing caps packed with grease?
This serves two purposes. It provides a continuous supply of grease for the bearings, and it also keeps the grease from migrating away. If the cap were empty, the grease might eventually work its way into the cap, filling the cap but leaving the bearings dry .
How often should you clean trailer wheel bearings?
