Rehau 317171-001 Everloc+ 1/2 Inches Pexa Compression Sleeve X 1/2 Inches Npt Brass Male Adapter Lead Free

Product Description

The REHAU 317171-001 is a lead-free brass male adapter designed for use with REHAU PEXa tubing in potable water, radiant heating, and hydronic systems. This fitting connects 1/2 inches EVERLOC+ compression-sleeve PEXa pipe to a 1/2 inches NPT male threaded port, making it a reliable transition fitting for plumbing rough-ins, manifold connections, and mechanical room installations. Plumbers, pipefitters, and hydronic contractors rely on this type of adapter wherever a PEXa system needs to tie into a threaded valve, manifold, or fixture connection point. The EVERLOC+ system uses a compression-sleeve installation method rather than a crimp ring or clamp ring, which means no open flame and no separate crimp tool calibration. The installer slides an EVERLOC+ sleeve over the PEXa pipe, inserts the fitting, and uses the EVERLOC+ compression-sleeve tool to complete the connection. The result is a permanent, pressure-tested joint. This fitting meets the performance standards set out in ASTM F877 and CSA B137.5 for SDR9 PEXa pipe, covering both temperature and pressure ratings. The NPT threads on this adapter conform to ANSI/ASME B1.20.1, which is the standard thread form used across North American plumbing and HVAC equipment. Male NPT threads, often noted as MPT or MNPT, taper inward so that the connection tightens as it is threaded into a female port, creating a leak-resistant mechanical seal when used with appropriate thread sealant or tape. The brass body resists corrosion and handles the temperature swings common in both domestic hot water and heating applications. All EVERLOC+ fittings, including this adapter, comply with the lead-free requirements of the U.S. Safe Drinking Water Act, making them approved for potable water installations across the United States.

• Designed exclusively for use with REHAU PEXa pipe and the EVERLOC+ compression-sleeve fitting system
• Lead-free brass construction meets U.S. Safe Drinking Water Act requirements for potable water use
• NPT male threads conform to ANSI/ASME B1.20.1 for reliable, standardized connections to valves, manifolds, and fixtures

Product Highlights

The REHAU 317171-001 EVERLOC+ male adapter gives plumbing and hydronic professionals a fast, flame-free way to transition from 1/2 inches PEXa tubing to a 1/2 inches NPT threaded connection. Lead-free brass construction and compliance with ASTM F877 and CSA B137.5 make it suitable for both potable water and heating system applications.
