Grooved end cap with concentric hole is used to be fitted onto the end of a pipe with a threaded concentric hole for drainage. This grooved end cap provides an economic and efficient method of reducing grooved piping systems.
HT Model XGQT06/20/21 is an ideal transition fitting for cases where a large reduction is required, such as 6x1" or 4"x1". It can be used as a cost-effective alternative to expensive swaged nipples.
