Sioux Chief 637-G23H Elbow 3/8 Comp X 3/4 Swivel Hose Thread

Product Description

The SIOUX CHIEF 637-G23H is a no-lead elbow fitting designed to connect 3/8 inch compression tubing to a 3/4 inch swivel hose thread port. The swivel end allows for easy alignment during installation without twisting the supply line, reducing stress on connected components. This fitting is used in potable water applications where lead-free construction is required by code. Plumbers and pipefitters install this type of transition elbow when routing supply tubing to appliances, fixtures, or equipment that terminate with a hose thread connection.

This elbow fitting is suited for residential and light commercial plumbing installations. Common applications include connecting copper or compatible compression tubing to washing machine supply valves, water heater fittings, and similar hose-thread outlets. The 90-degree elbow configuration helps route tubing in tight spaces where a straight fitting would not clear adjacent structure or cabinetry.

Key Features

• No-lead construction meets federal and state lead-free drinking water requirements
• 3/8 inch compression inlet accepts standard compression tubing without soldering
• 3/4 inch swivel hose thread outlet allows rotation for easy alignment
• Elbow configuration supports directional changes in confined installation spaces
• Lightweight at 0.19 pounds, reducing load on connected tubing and valves

Compatibility

Designed as an OEM-style replacement or new-installation fitting for plumbing systems requiring a 3/8 inch compression to 3/4 inch swivel hose thread transition at a 90-degree elbow.

Installation Notes

This fitting is installed by licensed plumbers working on potable water supply lines. Shut off the water supply and relieve line pressure before disassembling any existing connections. Compression fittings require proper seating of the ferrule against the tubing — do not overtighten, as this can crack the ferrule or distort the fitting seat. Installation must comply with applicable local plumbing codes and IPC lead-free requirements for potable water systems.
