Sioux Chief 645WG-3P No-Lead F1960 PEX x PVC Transition Adapter

Sioux Chief 645WG-3P No-Lead F1960 PEX x PVC Transition Adapter

The Sioux Chief 645WG-3P series is a no-lead F1960 PEX x PVC transition adapter built to connect underground PEX water service lines directly to in-house PVC piping systems. Available in F1960 PEX x PVC sizing from 3/4" through 1", this family gives plumbers and contractors a direct, code-grade transition point wherever a PEX service entry meets a PVC distribution system. Every size shares the same no-lead construction for potable water compliance and is intended for cold water applications only, eliminating the need for extra couplings or field-fabricated workarounds at the point where the two pipe materials meet at the water main entry. The adapter's F1960 end is engineered to accept expansion-style PEX tubing, while the opposite end is sized to match the corresponding PVC pipe diameter, allowing a single fitting to handle the entire material changeover.

Key Features

• Trade Size Range: Available in F1960 PEX x PVC sizing from 3/4" through 1", covering standard residential and light commercial water service connections.
• PEX Expansion Connection: The F1960 end accepts expansion-style PEX tubing, matching the ASTM F1960 expansion fitting standard referenced in the part design across the size range.
• PVC Transition End: The opposite end is sized to match the corresponding PVC pipe diameter, allowing a direct changeover from an underground PEX service line to in-house PVC piping.
• No-Lead Construction: Manufactured to a no-lead standard for potable water service applications on every size in the family.
• Cold Water Application: Rated for cold water use only, not intended for hot water distribution lines.
• Purpose-Built Transition Fitting: Designed specifically for hooking up PEX underground water service lines to PVC in-house piping systems.
• One-Piece Adapter: A single fitting handles the material changeover in one connection, reducing the number of joints at the service entry point.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing fittings for the demands of professional installation, and the 645WG-3P family of no-lead PEX-to-PVC adapters is engineered as a dedicated transition part rather than a generic bushing. With a no-lead build for potable cold water service and a direct F1960-to-PVC configuration available across the 3/4" to 1" size range, it gives contractors a straightforward, purpose-made way to bring an underground PEX water service line into a PVC in-house system without stacking multiple generic fittings at the transition point. Sourced from the United States and packaged 50 per carton, it is sized for stocking on service trucks handling routine PEX-to-PVC changeovers across multiple job sizes.
