At GF&D Systems you can order your grease fittings in bulk, or we'll poly-bag them for your customers with part numbers and barcodes printed on the bag. Grease fitting kits are also available, customized or standard, with private labeling in either boxes or clamshells

Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 96 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

The 14-28 thread fitting is used on cars, light trucks, and industrial machinery. The SAE-LT thread conforms to the Society of Automotive Engineers Lubrication Threads specifications. Requires a tapped hole for installation. Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

Industrial standard button head fittings are designed for use where volume flow of lubricant is required. This type of fitting is used when using on ground moving equipment, conveyors, mining and other heavy machinery. Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

hread forming (spin drive) fittings, have special tapered drive threads for fast production line installation in untapped hole, saving the tapping cost. A leakproof permanent seal is formed because the installation force causes the material of the untapped hole to reshape conforming to the fittings contour. Use in heat-treated parts is not recommended. Thread forming fittings can be replaced by any standard threaded fitting or by another thread-forming fitting. Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

United Fine Straight threads (UNF) are parallel, and are like the threads on a machine screw or bolt. They require a tapped hole for installation. Most commonly used on trucks, cars, and industrial machines. Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

For increased efficiency in production line installation, drive fittings are used in untapped holes and save time and money by removing the tapping requirements. Not recommended for use in high pressure applications. Favored for use by OEM's. (Original Equipment Manufacturers.) Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless.

Pipe Threads (PTF) are larger in diameter than most UNF or SAE-LT threads and also provide additional strength. PTF threads have a taper like SAE-LT threads to provide a leakproof installation. These threads are designated by nominal pipe diameter. The 18 PTF thread is about 38" diameter, and the 14 PTF thread is about 12" in diameter. A tapped hole is required for installation. PTF fittings are used most often in construction and in the agricultural industry where heavy machinery is required. Maximum Pressure is 8, 000 PSI. All zinc dichromate fittings minimum 72 hours to red rust. All zinc fittings case hardened to Vickers HV1 or 83 min Rockwell 15N. All stainless steel fittings are type 303 stainless

Relief FittingsYOUR 'ONE-STOP' SUPPLIER FOR GREASE FITTINGS & ACCESSORIESRelief Fittings are most commonly used on bearings (universal joints, king pins, etc.) and gearbox housings. Fittings open at pre-determined pressures. Most common are 14-1 PSI and 1-5 PSI

Flush type fittings are for use in applications where protrusion of the fitting is not tolerated. Some applications include line shaft pulleys and revolving bearings.
