Value Collection BDNA-7590 Button-head Grease Fitting

Product Description

The VALUE COLLECTION BDNA-7590 is a button-head grease fitting threaded at 1/8-27 NPT, designed for use with standard grease guns in lubrication maintenance applications. The low-profile button-head style allows grease to be injected at a flat angle, making it well suited for tight-clearance installations where a standard or angle-style zerk fitting will not seat a coupler properly. This fitting is a direct-thread fastener that mechanics, millwrights, and equipment technicians install on bearings, linkages, chassis components, and other grease-lubricated assemblies during preventive maintenance or rebuild work.

This fitting is used wherever a 1/8-27 threaded port is present and a low-profile grease point is required. Common applications include agricultural equipment, industrial machinery, automotive chassis, conveyor systems, and HVAC equipment with grease-lubricated bearing housings. The button-head design is chosen specifically when a grease gun coupler must engage a recessed or tight fitting location that a standard zerk would not accommodate.

Key Features

• Button-head profile provides a low-clearance grease point for confined installation spaces
• 1/8-27 thread size fits standard NPT-threaded grease ports on bearings and linkages
• Compatible with standard grease gun couplers rated for button-head fittings
• Compact form factor suited for preventive maintenance on industrial and mechanical equipment

Compatibility

Designed as an OEM-style replacement grease fitting for any mechanical assembly with a 1/8-27 NPT threaded grease port that requires a button-head style fitting.

Installation Notes

Installation is performed by mechanics or maintenance technicians using a standard open-end wrench or socket. De-energize or shut down the equipment and relieve any pressure from the lubrication system before removing the existing fitting. Thread the fitting in by hand first to avoid cross-threading, then torque to snug using hand tools. Confirm the grease gun coupler seats flush and that grease flows freely before returning the equipment to service.
