1/2 in Barb Crimp Copper Stub Out Elbow 8 in - 50 Pack

In this review the 50-Pack HeSun 1/2 in Barb Crimp Copper Stub Out Elbow is evaluated for installers and plumbers who need dependable stub-outs for potable water projects. The bottom line: this kit delivers consistent, lead-free copper fittings certified to ASTM F1807 and NSF/ANSI 61 standards, making it a practical choice when durability and code compliance matter most. Installers will appreciate the 8 in length and pre-drilled wall flange for repeatable mounting, while homeowners managing a renovation will find the 50-pack useful for multiple fixtures.

Key Features

• Lead-free copper construction: The all-copper design provides long-term corrosion resistance and safe potable water compatibility.
• ASTM F1807 and NSF/ANSI 61 certified: Certification ensures the fittings meet accepted standards for potable water installations.
• 8 in stub-out length with wall flange: The 8 in reach and pre-drilled flange make it easy to anchor the fitting flush to walls or floors for a neat installation.
• 1/2 in barb crimp connection: The barb detail is compatible with standard PEX crimp rings and stainless steel clamp rings for secure joints.
• 50-piece pack: Bulk quantity reduces repeat ordering and is convenient for multi-bath or new-construction plumbing runs.
• Broad compatibility: Works with copper rings and PEX crimp tools, though it is not intended for expansion systems or PB tubing.

Who It's For

This pack is aimed at professional plumbers and serious DIYers who need a reliable supply of code-compliant stub-outs for multiple fixtures or projects. The certified copper construction and pre-drilled flange suit new builds, remodels, and commercial jobs where potable water approval is required.

It is less suitable for systems that use expansion-style PEX fittings or PB (polybutylene) tubing, so customers committed to those connection methods should look for compatible fittings instead.
