EVERLOC fittings and sleeves create reliable connections that can be walled-in or embedded directly in a thermal mass when wrapped in waterproof, adhesive-free tape or RAUCROSS™ (Art. 253615, 253625) heat shrink tubing to help reduce corrosion caused by the surrounding environment. Check local codes for compliance. Installation is easy with EVERLOC tools. EVERLOC fittings are produced from solid brass stock. Elbows and tees are hot-forged for superior strength and durability, while straight fittings are machined from solid brass rod. EVERLOC fittings and sleeves meet the performance requirements of ASTM F877 and ASTM F2080. EVERLOC fittings are not certified for potable water applications.
