Sioux Chief 633X18 3/4" PEX x 3/4" FIP Dielectric Swivel Connector, No-Lead Brass

The Sioux Chief 633X18 is a 3/4" PEX x 3/4" FIP dielectric swivel connector built from Type L copper tube, designed to join PEX tubing to threaded fixture or valve connections without restricting flow. The brass FIP swivel nut is NL/DZR rated and ships with its own gasket, and the fitting uses a lead-free solder joint at the copper-to-brass transition. This connector is also available with an integral 600 WOG full port ball valve for jobs that need shutoff at the connection point.

Key Features

  • Trade Size: 3/4" PEX x 3/4" FIP swivel connection for tying PEX tubing runs into threaded fixture or valve ports.
  • Full-Flow Design: Dielectric fitting construction offers no restriction through the connection, maintaining full flow at the transition.
  • Type L Copper Tube: Fitting body is made from Type L copper tube for a solid, code-familiar rough-in connection.
  • Brass FIP Swivel Nut: Includes its own gasket for a sealed threaded connection; do not use pipe dope on the FIP swivel threads.
  • No-Lead / DZR Brass: NL/DZR swivel nut construction paired with a lead-free solder joint at the copper-to-brass joint.
  • Full-Port Option: Also offered with a 600 WOG full port ball valve built into the fitting for in-line shutoff.
