1/2 inch x 12 inch PEX Copper Stub Out Crimp x Copper

1/2" PEX Stub Out – Rigid Copper Support for Termination Points

The Sioux Chief 1/2" PEX Stub Out is designed to provide a transition point from flexible PEX tubing to a fixed outlet location, typically at fixture rough-ins. It features a rigid copper tube segment mechanically attached to a PEX connection fitting, allowing for stable protrusion through framing while maintaining system integrity.

This stub out assembly is used in conjunction with PEX-a, PEX-b, or PEX-c tubing systems and supports secure termination for lavatory, toilet, or other plumbing fixture supply lines. The product is manufactured to meet ASTM and UPC requirements for residential and commercial potable water systems.

Technical Specifications

• Material: Lead-free copper stub with factory-assembled PEX fitting (usually ASTM F1807, F2159, or F1960 compatible depending on configuration)
• Nominal Stub Out Size: 1/2 inch (Copper OD)
• Connection End: PEX barb or expansion fitting, depending on model
• Length: Varies by SKU; commonly 6", 8", or 12" projection
• Compliance: Certified to NSF/ANSI 61 and ASTM F877 (PEX tubing compatibility)

Installation Guidelines

Secure the PEX stub out using appropriate brackets or clamps at the framing penetration. Connect the PEX end using approved crimp, clamp, or expansion methods, depending on the fitting type. Stub outs should be terminated with a cap or test plug for system pressure testing prior to fixture installation.

This product is intended for non-movable supply risers and is not designed to replace angle stops or shutoff valves. For code compliance, ensure use of support plates where pipe penetrates wall surfaces and maintain minimum spacing from potential heat sources or electrical interference.

Use Cases

Commonly installed behind walls in residential and light commercial buildings, especially at sinks, toilets, and ice maker outlets. Supports vertical or horizontal installation and is compatible with most standard rough-in boxes and stub out brackets.

System Integration Notes

Sioux Chief PEX stub outs maintain compatibility with major PEX system types (including Uponor, Viega, NIBCO, etc.) when matched with correct joining technology. Copper stub provides a secure transition from flexible tubing to fixed-point valves or outlets, reducing risk of pipe movement or connection stress at fixture interface points.
