Schedule 40 PVC Pipe Tee Fitting Snap On x Fipt (1" x 1/2" Dia.) - 464-130 This type of tee can be used to add a tee to any piece of rigid pvc pipe. They are called snap-on tees because you simply apply glue or cement to your pipe and to your fitting and snap it onto the pipe. Once the cement is dry, simply use a drill to make a hole in the original pipe. Then simply screw your new pipe addition to the snap fitting. While these tees are not meant for higher pressure situations, they perform quite well in many applications, including irrigation and sprinkler systems. All of our Schedule 40 fittings are NSF rated 14 & 61, which means they are certified for use with potable (drinking) water. Maximum temperature is 140 degrees F.
