Sioux Chief 643XG Series Male Sweat x PEX No-Lead Transition Adapter

Sioux Chief 643XG Series Male Sweat x PEX No-Lead Transition Adapter

The Sioux Chief 643XG Series delivers a dependable male sweat (MS) x PEX transition adapter for plumbing contractors handling potable water rough-in, remodel, and repair work. Available in 1/2" and 3/4" sizes across the 643XG2 and 643XG3 configurations, this no-lead fitting joins copper or similar sweat-end supply piping directly to cross-linked polyethylene (PEX) tubing, eliminating the need for a separate mismatched connection point. Manufactured to a no-lead standard for compliant potable water installation, the 643XG Series is packaged in bulk cases of 1000 EA, giving contractors and plumbing wholesalers a consistent, code-conscious sweat-to-PEX adapter to stock for everyday rough-in work.
