Alemite AL304300 Giant Button Head Coupler Grease Fitting

Product Description

The ALEMITE AL304300 is a giant button head coupler grease fitting designed for high-volume lubrication points that require a secure, leak-free connection under pressure. This fitting accepts grease gun couplers in applications where standard fittings are insufficient, delivering lubricant directly to bearings, joints, and other wear surfaces. It is a common replacement or supplemental fitting in heavy equipment maintenance, fleet service, and industrial lubrication programs. Weighing 0.4 pounds, it is built for durability in demanding service environments and is sold individually.

The AL304300 is suited for use on heavy-duty machinery, agricultural equipment, construction equipment, and commercial vehicles where oversized lubrication fittings are specified. The giant button head profile is common in fleet maintenance shops and equipment service facilities where technicians work with high-capacity grease guns or pneumatic lubrication systems. It is installed wherever standard Zerk-style fittings do not provide an adequate grease delivery point for the application.

Installation Notes

Installation is typically performed by a licensed mechanic or equipment service technician. Relieve all pressure from the lubrication system and wipe the mounting area clean before removing the existing fitting. Use the appropriate thread size tap or fitting wrench to seat the new fitting without overtightening. Verify the coupler seats fully on the button head before applying grease to prevent blowoff under pressure.
