The Propress 1" x 1/2" Bell Reducer is of lead-free construction. Hard copper pipe is generally used for supply of hot and cold water in both commercial and residential applications. Rigid or hard copper is always soldered, crimped, or pressed as the form of connection. Copper offers a high level of resistance to corrosion, and needs fittings to get around bends and obstacles. Copper fittings also range in application. ProPress Fittings require only a smooth and clean connection area for the best press. ProPress is much faster than the general heat applications. This ProPress 1" x 1/2" Bell Reducer features a size drop that's over larger than a normal reducer. Different from the standard reducer, this bell reducer generally reduces down to a pipe size that's 2-5 sizes smaller.
