Pro-lube GFT1-8/27SFTST5 Grease Fitting 1/8-27 Ptf 5 Pack

Product Description

The PRO-LUBE GFT1-8/27SFTST5 is a self-forming thread grease fitting designed for lubrication points that lack pre-tapped threads. The fitting uses a 1/8-27 PTF thread standard and is manufactured from steel with a zinc finish. When driven into a drilled hole, the shank forms its own mating threads, eliminating the need for a tap. Operating pressure is rated at 6,000 psi, making it suitable for demanding lubrication service. Overall height is 0.62 inches with a shank length of 0.24 inches. Licensed technicians and mechanical tradespeople rely on this fitting for bearing housings, bushings, and other lubrication access points where thread preparation is impractical.

This fitting is used wherever a grease point must be created in an unthreaded bore on industrial, commercial, or mobile equipment. Typical applications include conveyor systems, agricultural machinery, construction equipment, and HVAC fan shaft bearings. The self-forming design speeds field installation and reduces the tooling required when adding or replacing grease zerks on existing equipment. Each order includes 5 fittings, supporting multi-point service work in a single package.

Compatibility

Designed as an OEM-style replacement grease fitting for any lubrication point requiring a 1/8-27 PTF self-forming thread zerk in steel equipment and machinery.

Installation Notes

Installation is performed by mechanics and maintenance technicians using a standard hex wrench or socket. Drill the correct pilot hole diameter per the fitting manufacturer specification before driving the fitting to allow proper thread formation. Do not overtighten, as excess torque can strip the self-formed threads or damage the fitting body. Ensure the equipment is depressurized and de-energized before servicing any lubrication point.
