Sioux Chief 644WG Series One-Piece No-Lead Brass FTG x F1960 Transition Adapter

Sioux Chief 644WG Series One-Piece No-Lead Brass FTG x F1960 Transition Adapter

The Sioux Chief 644WG Series is a one-piece, no-lead brass transition adapter available in 1/2" and 3/4" sizes (models 644WG2 and 644WG3), each transitioning an FTG (female sweat/solder) copper connection to a matching F1960 expansion-style connection. This transition design lets installers move between copper sweat piping and F1960-compatible piping systems within a single job without cutting in additional couplings. Every size in the 644WG Series is engineered for full flow with no restriction so water moves through the joint at the same rate as the surrounding copper and F1960 pipe instead of choking down at the connection point. Manufactured in the United States, this adapter family is built for professional plumbing and mechanical work where a dependable, code-aware copper-to-F1960 transition is required.

Key Features

• Trade Size Range: 1/2" and 3/4" FTG (female sweat/solder) x F1960 connections, sized for standard copper and F1960 piping.
• Durable Construction: One-piece no-lead brass body resists corrosion and holds up to repeated thermal cycling in potable water lines.
• Full Flow Design: Full flow with no restriction keeps water volume and pressure consistent through the transition point instead of narrowing at the joint.
• Model Configurations: Available as 644WG2 (1/2") and 644WG3 (3/4"), both built on the same one-piece no-lead brass, full-flow platform.
• One-Piece Fitting: Single-piece brass construction eliminates additional seams or union points that can become future leak paths.
