About Grease Fitting Threads

Grease Fittings

Inject lubricant into motors, bearings, engine blocks, and all kinds of machinery.

Grease Fitting Assortments

Assortments contain straight, 45° elbow, and 90° elbow fittings.

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.

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.

Flush-Style Grease Fittings

Use these fittings in tight spaces where protruding fittings won't work.

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.

Pin-Style Grease Fittings

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

Grease Fittings for Unthreaded Holes

Drive these fittings into unthreaded holes. They're also known as hydraulic grease fittings.

Self-Tapping Grease Fittings
for Unthreaded Holes

Ensure a secure fit in unthreaded holes—these fittings cut threads as they’re installed. They're also known as hydraulic grease fittings.
