Import 415590 90 Degree Grease Fitting 1/4-28 Zinc

Product Description

The IMPORT 415590 is a standard 90-degree head grease fitting designed to deliver lubricant to hard-to-reach grease points in mechanical assemblies. The 90-degree angle allows the fitting to be installed in tight spaces where a straight or 45-degree fitting would not clear surrounding components. Threaded at 1/4-28 UNF, it installs into standard tapped grease ports found on bearings, bushings, joints, and linkages. A zinc-plated finish provides basic corrosion resistance for shop, fleet, and field service environments. Installation requires a standard grease gun coupler and a wrench or socket sized for the fitting hex.

This fitting is suited for general industrial, automotive, agricultural, and equipment maintenance applications. It is used wherever rotating or sliding components require periodic lubrication and the geometry of the assembly demands an angled entry point. Maintenance technicians, fleet mechanics, and equipment service professionals install this fitting during preventive maintenance cycles or as a replacement for worn or damaged fittings on existing equipment.

Key Features

• 90-degree head angle for lubrication access in confined spaces
• 1/4-28 UNF thread for compatibility with standard tapped grease ports
• Zinc-plated finish for corrosion resistance in general service environments
• Standard grease fitting design accepts common grease gun couplers
• Compact size suited for dense mechanical assemblies

Compatibility

Designed as an OEM-style replacement grease fitting for any mechanical assembly with a 1/4-28 UNF tapped grease port requiring a 90-degree entry angle.

Installation Notes

A licensed mechanic or qualified maintenance technician typically installs grease fittings using a wrench or appropriate socket to seat the fitting snugly without overtightening the threads. Relieve any pressure from the lubrication point before removing an existing fitting. After installation, confirm the grease gun coupler seats and locks fully before applying lubricant to avoid unseating the fitting under pressure.
