Alemite AL1684-B Straight Hydraulic Grease Fitting

Product Description

The ALEMITE AL1684-B is a straight hydraulic grease fitting designed for standard lubrication points in mechanical and industrial equipment. This fitting accepts a grease gun coupler and allows technicians to inject grease directly into bearing housings, linkages, and other grease-zerk lubrication points. The AL1684-B measures 2-5/8 inches in length with a 1/8 PT thread connection, making it a direct-fit replacement for straight-style hydraulic fittings in a wide range of applications. At 0.09 pounds, it is a lightweight but durable single-piece fitting sold individually.

This fitting is used in maintenance and repair of agricultural equipment, construction machinery, automotive components, and general industrial machinery wherever straight-access grease points are present. Lubrication technicians, mechanics, and millwrights install these fittings when replacing damaged or worn grease zerks or when setting up new lubrication points. The 1/8 PT thread is a parallel tapered thread form common in hydraulic and lubrication fittings across a broad range of equipment platforms.

Key Features

• Straight configuration provides direct grease gun coupler access
• 1/8 PT thread for secure, leak-resistant installation in threaded ports
• 2-5/8 inch overall length suits standard straight-access lubrication points
• Lightweight at 0.09 pounds for easy single-hand installation
• Sold individually, compatible with standard grease gun couplers

Compatibility

Designed as an OEM-style replacement straight hydraulic grease fitting for equipment with 1/8 PT threaded grease ports requiring a straight-entry zerk configuration.

Installation Notes

Installation is typically performed by mechanics or lubrication technicians using an open-end wrench or fitting installation tool. Remove the old fitting and clean the threaded port before installing the new fitting to avoid cross-contamination of the lubrication point. Do not overtighten, as the PT thread seals on the taper and excess torque can damage the port. Confirm the grease gun coupler seats fully on the fitting head before applying grease pressure.
