The REHAU 104816-001 is a 1/2 inch EVERLOC+ PEX compression sleeve designed specifically for use with REHAU PEXa pipe. This sleeve is a core component of the EVERLOC+ compression-sleeve fitting system, which provides a reliable, tool-driven connection for residential and commercial plumbing, radiant heating, and hydronic systems. Plumbers and pipefitters working with PEXa tubing rely on this sleeve to complete secure, leak-resistant joints that meet industry pressure and temperature standards.
The EVERLOC+ system works by compressing a polymer sleeve over a PEXa pipe and fitting body using a dedicated EVERLOC+ compression-sleeve tool. This creates a cold-expansion-style connection without the need for open flame or soldering. The result is a fast, repeatable joint that holds up under sustained pressure and temperature cycling in both hot and cold water distribution systems.
This sleeve meets the temperature and pressure ratings outlined in ASTM F877 and CSA B137.5 for SDR9 PEX pipe. These are widely recognized standards for PEX plumbing systems used in the United States and Canada. The polymer construction resists corrosion and scale buildup, making it well suited for use in areas with hard water or aggressive water chemistry. The 1/2 inch size is one of the most common sizes used in residential water supply lines and radiant floor heating loops. Contractors running PEXa systems will find this sleeve easy to install in tight spaces where traditional copper fittings would require more clearance. Pair this sleeve with compatible REHAU EVERLOC+ fittings and the appropriate compression tool for a complete, code-compliant installation.
The REHAU 104816-001 EVERLOC+ compression sleeve delivers a code-compliant, flame-free PEXa pipe connection in a 1/2 inch size suited for water supply and radiant heating systems. Its polymer body and compression-style installation make it a practical choice for professional plumbers working with REHAU PEXa pipe.
