- Straight drive-in design simplifies installation in tight spaces

- Accepts grease gun pressure for reliable lubrication delivery
- Manufacturer part number 37581 ensures correct replacement identification
Straight Drive-In Grease Fitting
This zinc-plated steel fitting installs permanently in mechanical systems and provides a nipple for grease-gun attachment. It accepts lubricant under pressure and directs it into bearings or moving parts. The straight design suits inline access points on industrial and automotive equipment. Mechanics and maintenance technicians use it to simplify routine lubrication tasks.
3/16 inch capacity and pressure headroom
The 3/16 inch shank fits standard tapped holes and handles typical hand-operated grease-gun pressures. It delivers reliable flow for moderate-speed bearings and pivot points. Very high-pressure systems or oversized passages may exceed its sealing capability. Users should verify thread engagement depth before installation.
Replaces worn or missing lubrication fittings
This fitting upgrades damaged, corroded or absent nipples on existing machinery. The jump is worth it when the old fitting leaks, blocks or cannot accept a standard grease gun. It is not for threaded-port applications that require a screw-in base or for metric-threaded housings. Buyers needing angled access or button-head profiles should select a different style.
