Alemite AL321839 Lubrication Fitting

Product Description

The ALEMITE AL321839 is a lubrication fitting designed to provide a secure grease access point in mechanical assemblies. Also commonly referred to as a grease zerk or grease nipple, this fitting threads into a port on the component being serviced and accepts a grease gun coupler for controlled lubricant delivery. It is a standard maintenance hardware item found in a wide range of rotating and bearing-supported assemblies. Millwrights, equipment mechanics, and service technicians install and replace these fittings as part of routine preventive maintenance programs.

Lubrication fittings of this type are used wherever scheduled greasing is required, including electric motors, conveyor systems, agricultural equipment, automotive chassis components, and industrial machinery. The fitting creates a one-way valve that allows grease to be injected under pressure while preventing backflow and contamination ingress. Replacement is typically required when a fitting is damaged, stripped, or fails to accept a coupler properly.

Key Features

• Accepts standard grease gun couplers for straightforward lubrication service
• One-way check valve design prevents grease backflow and contaminant entry
• Sold individually, allowing targeted replacement of damaged fittings
• Lightweight at 0.02 pounds, consistent with standard zerk fitting construction

Compatibility

Designed as an OEM-style replacement lubrication fitting suitable for threaded grease ports in industrial, agricultural, and mechanical equipment applications.

Installation Notes

Lubrication fittings are typically installed and replaced by mechanics, millwrights, or equipment service technicians. Before replacing a fitting, relieve any system pressure and, where applicable, power down the associated equipment. Use the correct thread size tap or thread chaser if the receiving port is damaged before installing the new fitting. Avoid over-tightening, which can strip threads or crack the fitting body.
