Alemite AL304300-A Giant Button Head Grease Coupler

Product Description

The ALEMITE AL304300-A is a giant button head grease fitting coupler designed for use with grease guns in lubrication service applications. This coupler connects directly to button head grease fittings, providing a secure, leak-resistant seal during grease delivery. The giant button head style accommodates larger fitting heads commonly found on heavy equipment and industrial machinery. Licensed lubrication technicians, fleet mechanics, and heavy equipment service professionals install this coupler as part of routine preventive maintenance programs. At 0.45 pounds, it is a compact, single-piece component suited for frequent use in the field or shop.

This grease fitting coupler is used wherever button head style zerk fittings are specified on heavy-duty equipment, including agricultural machinery, construction equipment, and industrial conveyance systems. The giant button head design is intended for applications where standard coupler heads do not seat properly on oversized or recessed fittings. It is sold individually, making it a straightforward replacement or spare for existing grease gun setups.

Key Features

• Giant button head design seats securely on oversized button head grease fittings
• Single-unit construction for direct attachment to standard grease gun hoses
• Sold individually for targeted replacement or spare inventory
• Lightweight at 0.45 pounds for easy one-handed operation

Compatibility

Designed as an OEM-style replacement coupler for use with grease guns equipped with standard threaded hose ends that accept button head style couplers on heavy-duty lubrication fittings.

Installation Notes

Installation is performed by lubrication technicians or mechanical service professionals. Before servicing any grease fitting, relieve pressure from the grease gun and wipe the fitting head clean to prevent contamination. Thread or snap the coupler onto the grease gun hose per the manufacturer connection type, then seat it firmly over the button head fitting before applying grease. Do not over-pressurize the fitting if resistance is felt, as this may indicate a blocked or damaged zerk.
