45 Elbow 3/8" Sweat x 3/8" Sweat NIBCO W01330T Copper 10-Pack 1.14x0.88x0.56 in The NIBCO W01330T 45-degree copper elbow is a lead-free, pressure-rated fitting designed for use in residential and commercial plumbing systems carrying potable water, hydronic heating, or refrigeration lines. Made from ASTM B75 Alloy C12200 (DZR?dezincification resistant) copper, it features 3/8-inch sweat (solder) connections on both ends for secure, permanent joints with compatible copper tubing. The 45-degree bend allows smooth directional changes in tight spaces while maintaining optimal flow and minimizing turbulence. Certified to NSF/ANSI 61 and 372 for drinking water safety and manufactured to ASME B16.22 and MSS SP-104 standards, this fitting supports working pressures up to 912 psi and temperatures from -20F to 400F. Sold in a 10-pack for efficient use in multi-joint installations, it is suitable for above-ground and underground applications.
