Sioux Chief 647WG2 1/2" FIP x 1/2" F1960 No-Lead Brass Adapter

Sioux Chief 647WG2 1/2" FIP x 1/2" F1960 No-Lead Brass Adapter

The Sioux Chief 647WG2 is a 1/2" FIP x 1/2" F1960 no-lead brass adapter designed to transition threaded iron pipe into PEX expansion tubing on rough-in supply lines. Machined as a single one-piece brass body, it mates a 1/2" female iron pipe (FIP) thread on one end to a 1/2" F1960 PEX expansion connection on the other, giving installers a durable transition point behind the wall or under the floor. Because the fitting is no-lead brass, it is built for potable water supply installations where a threaded stub-out needs to convert to PEX expansion tubing without adding extra couplings.

Key Features

• Trade Size: 1/2" FIP x 1/2" F1960 for a direct, one-fitting transition between threaded iron pipe and PEX expansion tubing.
• Durable Construction: One-piece no-lead brass body resists corrosion and stands up to rough-in installation behind walls and under floors.
• Dual Connection Design: A 1/2" FIP threaded end pairs with a 1/2" F1960 PEX expansion end, combining two connection types in a single fitting instead of two separate adapters.
• No-Lead Brass: Manufactured from no-lead brass alloy suited to potable water supply lines.
• One-Piece Body: Single-piece machined construction reduces the number of joints and potential leak points compared to multi-part adapter assemblies.
• Rough-In Application: Sized for 1/2" branch and supply runs typical of residential and light commercial water distribution.

Why Sioux Chief?

Sioux Chief manufactures the 647WG2 from one-piece no-lead brass for dependable performance in potable water rough-in applications. The single-piece design reduces the number of joints and potential leak points compared to multi-component adapters, giving plumbing contractors a durable transition fitting between threaded pipe and PEX expansion systems on the job site. It is a straightforward, no-lead brass solution for converting a threaded stub-out to PEX expansion tubing without stacking multiple fittings.
