VESDA VP-TEE-FPT is a 3/4 in. x 3/4 in. x 1/2 in. FPT CPVC tee for VESDA aspirating smoke detection sampling pipe, supplied 10 per box.
The two 3/4 in. sockets join the main sampling pipe, while the 1/2 in. female threaded branch provides a take-off point. Xtralis shows this FPT tee in concealed sampling layouts, where capillary tube runs from the sampling pipe to a miniature sampling point in a ceiling tile. Like the rest of the VESDA pipe range, it is made from specialty CPVC and joined with a one-step solvent cement.
