Pipe Caps

In stock

A range of Pipe Caps that protect threaded and non-threaded NPT pipe ends. The cap is sized and designed for positive-gripping power over the outside diameter of the pipe.

The cap eliminates the ingress of contaminants and foreign materials, as well as protecting the pipe end from damage. Several styles with special features are available in this range.

This includes caps that have a vent hole for the prevention of pressure build up inside the pipe, which may otherwise force the cap off. The range also features lightweight options with internal rings to help reinforce a positive-grip and heavy duty caps with a thicker base for added protection over the outside diameter of the pipe.

  • Material: Polyethylene (PE)
  • Colors: Black, Blue, Orange, Red and Yellow
