100-Pack PEX Fittings 1/2 in Female NPT Drop Ear Elbow - Durable Brass

In this review the 100-Pack HeSun PEX fittings are evaluated for plumbers, contractors, and advanced DIYers who need a reliable supply of elbows for potable water systems. The bottom line: this pack stands out for consistent, lead-free brass construction certified to industry standards, making it a practical choice when bulk, compatibility, and corrosion resistance matter. The reviewer found the set best for routine hot and cold PEX work where crimp-style installation is used and appreciated the cost-per-piece value when outfitting multiple runs.

Key Features

• Lead-free brass construction: Provides durability and resistance to corrosion and rust, helping fittings last in typical plumbing environments.
• ASTM F1807 and NSF/ANSI 61 certified: Ensures these fittings are approved for potable water applications and meet recognized performance standards.
• High temperature tolerance: Rated for use between 32F and 200F so the elbows can be used in both hot and cold water systems without degrading.
• Broad compatibility: Works with PEX A, B, and C tubing and common crimp installation methods such as stainless steel clamp rings and copper rings.
• Bulk pack of 100: The large pack size reduces the need to reorder for larger projects and offers predictable inventory for job sites.
• Drop ear elbow form factor: Provides a convenient 90-degree turn with mounting options useful for fixture connections and tight spaces.

Who It's For

The 100-Pack is aimed at professional plumbers, HVAC installers, and experienced DIYers who install or repair multiple PEX lines and need a reliable bulk supply of elbows. Because these fittings are certified for potable water and resistant to corrosion, they are particularly suitable for residential plumbing, radiant heating returns, and general building maintenance.

Those who should look elsewhere include users of expansion-style PEX systems or PB tubing, since these fittings are not compatible with expansion fittings. Beginners who plan to use a different joining system may prefer single or mixed-size assortments rather than a 100-pack of a single elbow type.
