1/2 in Barb Crimp Copper Stub Out Elbow 6 in Length - 20 Pack

In this review the HeSun 20-pack 1/2 in barb crimp copper stub out elbows are judged as a practical, contractor-friendly option for retail plumbing projects and repairs. The bottom line: this kit is best for installers needing a reliable, lead-free copper stub-out that meets potable water standards and speeds installation with pre-drilled flanges. The reviewer found the long 6 in length and ASTM F1807/NSF/ANSI 61 certification to be the single biggest reasons to buy for wall or floor feed applications where a durable copper connection is required.

Key Features

• Certified material: Constructed from high-quality copper and certified to ASTM F1807 and NSF/ANSI 61, the elbows are suitable for potable water use and meet drinking water safety requirements.
• Lead-free construction: The all-copper design provides a long-lasting, corrosion-resistant connection that avoids lead contamination concerns for domestic plumbing.
• 6 in stub length: The extended 6 in length gives extra reach through walls or floors, making alignment and fixture connections easier for sinks, toilets, and other fittings.
• Pre-drilled wall flange: Each stub-out includes a flange with mounting holes to stabilize the fitting during rough-in and speed up installation on framed walls.
• Compatibility: Works with PEX systems using stainless steel clamp rings, PEX crimp tools, and copper rings for a secure crimped connection to 1/2 in PEX or copper tube.
• Quantity pack: The 20-pack provides enough fittings for multi-fixture jobs or to keep as a jobsite spares kit.

Who It's For

This kit is aimed at professional plumbers, handymen, and experienced DIYers who install or repair potable water lines and prefer copper components for durability and regulatory compliance. It is particularly useful on remodels or new construction where multiple stub-outs are needed and installers value the time saved by pre-drilled flanges and consistent copper fittings.

Those who should look elsewhere include users committed to expansion-style PEX systems or PB tubing, since these elbows are not suitable for expansion fittings. Also, installers who require integrated shutoff stops or different connection types should consider alternate fittings.

Pros & Cons

Pros

• Certified to ASTM F1807 and NSF/ANSI 61, assuring suitability for potable water installations.
• Lead-free, all-copper construction provides durability and corrosion resistance for long service life.
• Pre-drilled wall flange and 6 in length make mounting and alignment faster on typical wall and floor feeds.
• 20-pack quantity reduces trips to supply and keeps spares on hand for larger jobs.

Cons

• Not compatible with expansion PEX systems or PB tube, limiting use to crimp/clamp style connections.
• Fixed 6 in length may be excessive in tight spaces where shorter stub-outs are preferred.
