1/2" FNPT x Copper Press Dielectric Union, P-571NL (Lead Free)

Lead-free design is suitable for all no-lead potable water installations, in full compliance of the National lead-free plumbing law (111-380). Made to reduce stray current and galvanic corrosion where two dissimilar metals are joined. Self-aligning, non-conductive elastomer gasket and thermoplastic insert create a positive seal and complete isolation between the tubing and piping ends. With high-strength, galvanized forged steel construct, the P-571NL is intended for both residential and commercial applications. Manufactured for installation onto ASTM B88 types K, L, and M hard-drawn copper tubing. Coiled (annealed) soft copper tubing is not recommended for use with this product. Hide Description
