Options Features Applications
Tailpiece Kits (TPK) are accessories for water pressure reducing valves. These kits are comprised of a cast
brass union nut (ASTM B584), a EPDM gasket and a specific type of tailpiece for direct connection to
specific types of piping. Tailpiece kits are available for connection to FNPT, MNPT, female copper SWT,
male copper SWT, PEX (male barb), CPVC and compression (male) piping systems. A valve may utilize
two different tailpiece kits for connection to two dissimilar piping systems. An example of this
scenario is having copper sweat piping on the valve inlet and PEX piping on the outlet. By using a TPKC
on the inlet and a TPKPEX on the outlet, the valve will bridge the dissimilar piping systems.
