Pro-lube BHC/10/N Button-head Grease Gun Coupler Npt

Product Description

The PRO-LUBE BHC/10/N is a button-head grease gun coupler designed for direct connection to standard grease fittings in lubrication service applications. It features a 1/8 inch NPT thread and is rated for 3,000 psi operating pressure, making it suitable for high-pressure grease delivery tasks. The zinc-plated finish provides corrosion resistance for extended service life in shop and field environments. Lubrication technicians, mechanics, and equipment service professionals install this coupler as part of a complete grease gun assembly to deliver lubricant accurately to bearing housings, chassis fittings, and other grease points.

This coupler is used in automotive, industrial, and equipment maintenance settings where consistent, controlled grease application is required. The button-head design is the most common style for general-purpose grease gun use, allowing quick coupling and decoupling at standard zerk fittings. It is appropriate for both shop-based and field service work on a wide range of mobile and stationary equipment requiring routine lubrication.

Key Features

• Button-head coupler design for use with standard zerk grease fittings
• 3,000 psi operating pressure rating for high-pressure grease gun use
• 1/8 inch NPT thread for compatibility with standard grease gun hose connections
• Zinc-plated finish for corrosion resistance in shop and outdoor service environments
• Compact, lightweight construction at 0.06 pounds

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for standard grease guns equipped with 1/8 inch NPT hose fittings and used with button-head style zerk grease fittings.

Installation Notes

Installation is performed by lubrication and equipment maintenance technicians. Thread the coupler onto the grease gun hose or extension using the 1/8 inch NPT connection and ensure the joint is wrench-tight to prevent leakage under pressure. Relieve all pressure from the grease gun before removing or replacing the coupler. Do not exceed the rated 3,000 psi operating pressure.
