Buying Guide

What to consider when choosing a PEX stub out with flange

• PEX type compatibility: Determine if your system uses PEX-A, PEX-B, or PEX-C. Copper stub outs often specify compatibility; use PEX-A for expansion fittings and PEX-B/C for crimp or barb connections when stated.
• Flange presence and installation: A wall flange helps conceal the stub out and can simplify mounting. Check flange hole patterns and whether pre-drilled holes are included.
• Elbow length and diameter: Standard sizes are 1/2″ with 6″ length, suitable for typical residential supply runs. Confirm local code requirements for stub-out length and clearance.
• Material and durability: Copper is durable and resistant to corrosion but ensure compatibility with your tubing type and tools. Avoid mixing incompatible materials without adapters.
• Installation method: Barb-crimp, expansion, or compression connections require appropriate tools and fittings. Choose products that align with your existing installation method.
• Aesthetics and finish: If visible, finishes like chrome on covers offer a neat look. Balance aesthetics with functionality for under-sink or behind-wall installations.

Practical questions for buyers

• Do I need copper stub outs for PEX-A, B, or C? Choose based on the tubing type specified by the product. PEX-A uses expansion fittings, while B/C may use crimp or barb connections.
• Should I buy a pack of 10 or more? If remodeling multiple lines, a bulk pack reduces trips to the store and ensures uniform fittings.
• Can I use a stub out cover as a substitute for an elbow? No. Covers provide finishing assistance and pipe guidance, not actual elbow connections.
• Are wall flanges required? Flanges help conceal the stub outs and support clean installations, especially in visible areas.
• What tools are needed? Expansion systems require expansion tools and rings; crimp systems require crimping tools. Verify compatibility with your chosen product.
• Is there a risk of using the wrong PEX type? Yes. Mismatching PEX types with copper stub outs can cause leaks or poor connections. Always confirm tubing type before installation.

Additional quick references

• For PEX-B or PEX-C, prioritize products explicitly listing compatibility with B or C types.
• When selecting a bulk set, ensure the length and diameter match your installation plan to avoid waste or mismatches.
• Use a flange-equipped stub out where neat wall finishing matters, such as behind sinks or in exposed utility spaces.

FAQ

• What is a stub out with a flange? It is a short section of pipe with an elbow and a flange that mounts to the wall for a clean finish and easy access to connections.
• Can I mix PEX types with copper stub outs? Only if the product specifies compatibility with those PEX types and you follow the correct installation method.
• Do copper stub outs require special tools? Expansion-based PEX-A requires expansion tools; crimp-based PEX-B/C uses crimping tools. Check product guidance.
• Are wall flanges necessary? They improve aesthetics and provide mounting stability, especially in visible areas.
• What is the typical length for stub outs? Many standard stub outs are 6 inches long, which matches common sink and fixture layouts, but verify your space.
