Rehau 418433-001 Everloc+ Fnpt Ball Valve 1/2 Inches Compression X Fnpt

Product Description

The REHAU 418433-001 is a 1/2 inches EVERLOC+ FNPT Ball Valve designed for use in PEXa plumbing systems where a reliable, lead-free shutoff solution is needed. This brass ball valve uses a compression-sleeve connection on one end and a female NPT (FNPT) threaded connection on the other, making it easy to integrate into both PEX and threaded pipe assemblies. It is part of the REHAU EVERLOC+ compression-sleeve fitting system, which delivers consistent, high-strength connections without the need for open flame or soldering at the PEX side. Plumbers and mechanical contractors working on residential and commercial water distribution systems trust EVERLOC+ fittings for their durability and ease of installation. The valve body is constructed from brass, offering corrosion resistance and long service life in potable water applications. Connections on the PEX side are made using EVERLOC+ compression-sleeve tools, following all published REHAU Technical Guidelines for proper installation. The maximum temperature and pressure ratings of this fitting comply with ASTM F877 and CSA B137.5 for SDR9 PEXa pipe. When transitioning to a solder connection at the FNPT end, solder the valve in the open position and complete the solder joint before connecting the fitting to REHAU PEXa pipe. This sequencing protects the valve seat and internal components from heat damage. All EVERLOC+ fittings and sleeves, including this ball valve, meet the lead-free requirements of the U.S. Safe Drinking Water Act, making them compliant for potable water use across the United States. This valve is a practical choice for isolation points in hydronic systems, domestic water supply lines, and mechanical rooms where space and reliability are priorities.
