1/4 in. NPT Straight Head Drive Grease Fitting Zerk Kit

The 1/4 in. NPT Straight Head Drive Grease Fitting Zerk Kit is the most commonly used grease fitting at BH-USA. The push-in grease fitting is used on our flat-plate hoists, drive pipe supports, and all other products requiring grease. The simple, press-in design requires no threading to replace a worn or broken fitting. Works with any product that uses a 1/4 in. grease fitting. The ribbed design holds the fitting tightly into place.   The grease gun nozzle attaches to the fitting then you can inject grease. NPT means American National Standard Pipe Thread. Made from brass material. To replace use pliers to remove old zerk. The kit includes 6 grease zerks.

Designed for fast installation in untapped holes, Drive Type Grease Fittings save thread tapping costs. Hole size and shank dimensions are for reference only. Tests should be conducted to determine the correct hole size, which varies depending on the metal type and hardness. The serrated shank of Drive Type Grease Fittings makes it easier to replace damaged grease fittings in old or oversize holes. While drive fittings grip securely, they are recommended for low and medium pressures. For ease of installation and to prevent damage, drive fitting tools are recommended.
