Alemite AL1723-B 90 Degree Grease Fitting 1/8 Npt

Product Description

The ALEMITE AL1723-B is a 90-degree grease fitting designed for lubrication points where a straight fitting cannot be accessed or installed. Built with a 1/8-inch NPT Special Taper thread and an overall length of 49/64 inches, this fitting delivers a compact profile suited for tight-clearance applications. It is engineered for installation in bores with a hole size between 0.373 and 0.380 inches. Lubrication technicians, mechanics, and millwrights install these fittings on rotating equipment, linkages, and bearing housings to maintain proper grease distribution during preventive maintenance cycles.

This fitting is used wherever standard straight grease fittings are blocked by adjacent components, structural members, or housing geometry. Common applications include industrial machinery, agricultural equipment, construction equipment, and automotive chassis components. The 90-degree angle allows a grease gun coupler to engage the fitting head without clearance issues that would otherwise make lubrication difficult or impossible. The 1/8-inch NPT Special Taper thread ensures a secure, leak-resistant connection into the threaded bore.

Key Features

• 90-degree body angle for access in confined or obstructed lubrication points
• 1/8 inch NPT Special Taper thread for a secure, leak-resistant fit
• 49/64 inch overall length provides a low-profile installed footprint
• Designed for bores with a hole size of 0.373 to 0.380 inches
• Sold individually, suitable for single-point replacement or new installation

Compatibility

Designed as a standard replacement or new-installation grease fitting for equipment with 1/8-inch NPT Special Taper threaded lubrication ports and bore sizes between 0.373 and 0.380 inches.

Installation Notes

Installation is typically performed by a mechanic, lubrication technician, or millwright using an appropriate open-end wrench or fitting installation tool. Thread the fitting in by hand first to avoid cross-threading, then tighten to achieve a snug, leak-free seat without over-torquing. Verify the grease gun coupler seats fully on the fitting head and that the check ball purges freely before returning equipment to service. Always relieve any pressure from the lubrication system before removing or replacing fittings.
