1/2ft Pex Fittings Set 45 PCS - Brass PEX B Combo Kit

Our review of this 1/2' Pex fittings set finds it best suited to homeowners, RV owners and pros who work with PEX B lines and need a practical assortment of durable brass connectors. The single biggest reason to buy is the complete 45-piece combo that covers common 1/2' plumbing needs with ASTM F1807 and NSF/ANSI 61 compliant, lead free brass - a strong choice when potable water compatibility and corrosion resistance matter.

Key Features

• Complete 45-piece kit: Includes 15 elbows, 15 tees and 15 couplings so you can handle multiple repairs or a small run of 1/2' PEX B plumbing without sourcing individual parts.
• Lead free brass construction: Complies with drinking water standards for safe use on potable water systems and reduces contamination risk compared with plated fittings.
• ASTM F1807 certification: Meets a common PEX crimp fitting standard so compatibility and connection integrity are predictable for PEX B crimp systems.
• Corrosion and temperature resistance: Brass construction resists rust and tolerates typical hot and cold distribution temperatures from 32F to 200F.
• Works with standard crimp or clamp rings: Designed for use with stainless steel clamp rings or PEX crimp copper rings, offering flexibility with common installation methods.

Who It's For

This kit is ideal for do-it-yourselfers, handymen and plumbers who routinely work on 1/2' PEX B lines in homes, warehouses or RVs and want an on-hand selection of elbows, tees and couplings. The mix of parts is convenient for small projects, repairs and hydronic heating branches where 1/2' PEX B is specified.

It is not appropriate for systems that use expansion-style fittings such as UPONOR/Wirsbo or for PB tube systems, so professionals working exclusively with those systems should look elsewhere. Also note clamp rings are not included, so buyers must supply appropriate stainless clamp or copper crimp rings.
