Grease Fittings

Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point.

Leakproof Grease Fittings

Keep thin grease from leaking out—the check valve on these fittings has a Buna-N seat that creates a tighter seal than check valves on other grease fittings.

Grease Fitting Assortments

Keep a variety of grease fitting shapes, styles, and sizes on hand.

Safety-Vent Grease Fittings

To protect equipment from damage, the slit in the threads of these fittings acts like a breather vent, releasing any excess pressure and grease.

Flow-Stop Grease Fittings

Prevent damage to bearing seals caused by over-lubrication—these fittings automatically stop grease flow when pressure is within the shut-off range.

Button-Head Grease Fittings

Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won't pop off when adding grease.

Flush-Style Grease Fittings

The nipple doesn't stick out, so these fittings fit in tight spaces and won't be damaged if something knocks into them.

Pin-Style Grease Fittings

The pins on these fittings lock with dispensing tips for pin-style fittings to create a tight seal.

Self-Tapping Grease Fittings for Unthreaded Holes

To fit securely in unthreaded holes, these fittings cut threads as they’re installed.

Grease Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes.

Flush-Style Grease Fittings for Unthreaded Holes

Since they don’t protrude, these fittings avoid damage from impact and fit in tight spaces. Use a hammer and grease fitting installation tool to drive them into unthreaded holes.

Self-Tapping Flush-Style Grease
Fittings for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. Use these fittings in tight spaces where protruding fittings won't work.

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Remote-Access Grease Fittings

Access difficult-to-reach lubrication points from up to 10 ft. away.

Grease Fitting Cleaning Tools

Flush out clogged grease in your fitting. Tapping these tools with a hammer forces light oil through your fitting and removes contamination from bearings, joints, and other parts.

Grease Fitting Tools for Unthreaded Holes

Tap these tools once or twice with a hammer to install fittings.

Grease Fitting Tools for Threaded Holes

Remove worn fittings and repair threaded holes.

Grease Fitting Manifolds

Save time by sending grease from one fitting to multiple points. These manifolds come with everything you need to set up a remote lubrication system.

Grease Fitting Dust Caps

Keep grease fittings free of dirt and moisture.

Oil Fittings

Install these fittings into threaded holes.

Oil Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes.

Grease Dispensers

Grease-Dispensing Tip Adapters

Dispense from grease guns into grease fittings and bare lubrication points.

Grease-Dispensing Tips

Dispense from grease guns into grease fittings and bare lubrication points.

Precision Grease-Dispensing Tips

Penetrate gaskets, sealed bearings, and joints to deliver grease to precise locations.

Rigid Precision Grease-Dispensing Tip Adapters

These rigid tip adapters penetrate gaskets, sealed bearings, and joints to deliver grease to precise locations.

Flexible Precision Grease-Dispensing Tip Adapters

Penetrate gaskets, sealed bearings, and joints to deliver grease to precise locations.

Flexible Grease Nozzles with Dispensing Tip

These flexible nozzles come with a dispensing tip and have threads on one end for connecting to a grease gun.

Rigid-to-Flexible Grease Nozzles with Dispensing Tip

Slide the metal sleeve up to the tip for rigidity. Slide it back down to expose the flexible nozzle.

Rigid Grease Nozzles with Dispensing Tip

These rigid nozzles come with a dispensing tip and have threads on one end for connecting to a grease gun.

Grease Nozzles with Precision Dispensing Tip

Penetrate gaskets, sealed bearings, and joints to deliver grease to precise locations.

Rigid Grease Nozzles

With threads on both ends, these rigid nozzles connect grease guns to dispensing tips.

Flexible Grease Nozzles

These flexible nozzles have threads on both ends for connecting a grease gun to a dispensing tip.

Grease Gun Attachment Sets

Sets include dispensing tips for grease fittings and bare lubrication points.

Adapters for Male Threaded
Grease-Dispensing Tips

Convert dispensing tips with male threads into quick-disconnect couplings.

Rigid Grease-Dispensing Tip Extensions

Lubricate standard grease fittings in hard-to-reach areas. Extensions have a quick-disconnect fitting that snaps into your dispensing tip for standard grease fittings.

Flexible Grease-Dispensing Tip Extensions

These flexible extensions have a quick-disconnect fitting that snaps into your dispensing tip, so you can lubricate grease fittings that are hard to reach.

Swivels for Container-Mount
Grease Dispenser Nozzles

Move grease-dispensing guns in any direction without kinking the outlet hose.
