Sioux Chief PowerPEX® 645PX43 Coupling, 1 in F2159 PEX x 3/4 in F2159 PEX, Polymer

Sioux Chief PowerPEX® ASTM F2159 polymer fittings utilize high-performance, engineered polymer materials designed for use in potable water applications. Extensive research and testing has been performed on the quality and durability of these materials when used in potable water applications. ASTM F2159 fittings are designed for use with a copper crimp ring or the F877 V-Sleeve™, both of which provide 360 deg of compression around the sealing barbs. Stainless steel cinch clamps can also be used with the PowerPEX ASTM F2159 fitting system.
