100-Pack HeSun 1 in PEX x 1 in Male Sweat Adapter - Durable Brass

Our review of the 100-Pack HeSun 1 in PEX x 1 in Male Sweat Adapter finds it best suited for plumbers, contractors, and DIYers who regularly work on potable water or heating systems and need a large quantity of reliable brass crimp adapters. The single biggest reason to buy is consistency: these adapters are made from lead-free brass and are certified to ASTM F1807 and NSF/ANSI 61, which means they can be trusted in hot and cold water supply lines where code-compliant, corrosion-resistant components are required.

Key Features

• Pack Quantity: A 100-pack provides a bulk supply that reduces reordering and is cost-effective for large jobs.
• Material Quality: Made from lead-free brass for resistance to corrosion and rust, which helps extend service life in wet environments.
• Temperature Rating: Rated to perform across typical plumbing ranges (32F to 200F), suitable for hot water and heating applications.
• Standards Compliance: Certified to ASTM F1807 and NSF/ANSI 61, meaning these fittings are approved for potable water installations.
• Compatibility: Designed for PEX A, B, and C pipes and works with stainless steel clamp rings, PEX crimp tools, and copper rings for flexible installation options.
• Versatile Use: Usable indoors or outdoors in hot and cold supply lines and many heating systems, adding flexibility for a variety of projects.

Who It's For

This product is aimed at professionals and serious DIYers who run frequent plumbing jobs and need code-approved brass adapters in bulk. It makes sense for renovators replacing multiple fittings, heating contractors installing looped systems, and plumbing teams who prefer crimp-style connections.

Those who should look elsewhere include installers using expansion-style PEX systems or working with PB tube, as these adapters are not suitable for those systems. If only a couple of fittings are needed for a one-off repair, a smaller pack may be more economical.
