Pro-lube GFT182790SFTST5 Grease Fitting 1/8-27 Ptf Steel 5-pack

Product Description

The PRO-LUBE GFT182790SFTST5 is a self-forming thread grease fitting designed for 1/8-27 PTF threaded ports. Made from zinc-finished steel, this fitting cuts its own threads as it is driven into soft metal housings, eliminating the need for pre-tapped holes in many applications. It is rated to 6000 psi operating pressure, making it suitable for heavy-duty lubrication service in demanding mechanical assemblies. Sold in a pack of five, this fitting is installed by lubrication technicians, maintenance mechanics, and HVAC or equipment service professionals working on bearings, linkages, and fittings that require periodic greasing.

This grease fitting is used in residential and commercial equipment maintenance wherever 1/8-27 PTF porting is required. Typical applications include motor bearings, fan assemblies, pump housings, industrial linkages, and other mechanical components that receive grease through a standard zerk-style service port. The self-forming thread design is particularly useful when installing into aluminum, cast iron, or soft steel housings where cutting a clean thread on installation saves time and reduces rework. Each pack contains five fittings for stocking service kits or completing multi-point lubrication jobs.

Key Features

• Self-forming thread design cuts threads on installation - no pre-tapping required in compatible housings

• 6000 psi operating pressure rating for heavy-duty lubrication service
• Zinc-finished steel construction for corrosion resistance
• 0.76 inch overall height with 0.20 inch shank length for low-profile fitment
• Pack of 5 for service kit stocking or multi-point installations

Compatibility

Designed as an OEM-style replacement grease fitting for mechanical assemblies and equipment components using 1/8-27 PTF threaded lubrication ports.

Installation Notes

Installation is performed by qualified maintenance or service technicians using a standard fitting driver or appropriately sized wrench. Verify the port material is compatible with self-forming thread installation before driving the fitting. Always relieve system pressure and shut down the equipment before servicing any lubrication fitting. Do not overtighten, as self-forming threads in softer base materials can strip if excessive torque is applied.
