Alemite AL1851 Flush Type Grease Fitting 5/16 Hex

Product Description

The ALEMITE AL1851 is a standard flush type grease fitting designed for lubrication points where a low-profile or recessed fitting is required. The flush design sits level with or below the surrounding surface, protecting the fitting head from impact and contamination in tight or high-traffic service areas. Sized at a 5/16 inch hex with a 1/4 inch drive, it is compatible with standard grease guns and hand tools used in industrial, fleet, and equipment maintenance applications. Lubrication technicians and mechanical service professionals install this fitting as a direct OEM-style replacement or new installation on equipment requiring a flush-mount lubrication point.

The AL1851 is suited for use on industrial machinery, agricultural equipment, construction equipment, fleet vehicles, and any mechanical assembly where a standard protruding grease fitting would be exposed to damage or interference. The flush design is commonly specified in OEM assemblies where clearance is limited and fitting protection is a priority. It is sold individually and is appropriate for single-point replacements or small-quantity installations.

Installation Notes

Installation is performed by lubrication or mechanical service technicians using a standard hex socket or wrench sized to the 5/16 inch hex. De-energize and relieve pressure from the equipment before replacing any lubrication fittings. Avoid over-torquing the fitting during installation to prevent thread damage in the base material. Verify the fitting is fully seated flush before resuming equipment operation.
