Increasing flex pump connector, 150# ANSI (OD & drilling) carbon steel plate flanges (small flange is attached to a schedule 40 steel concentric reducer), 321 stainless steel annular corrugated hose and single 304 stainless steel over-braid. Suitable for use with many pump discharge applications. Absorbs pump vibration to reduce noise and also reduces the piping size from the pump to the mating piping at the same time. Its dual purpose saves you time and money. Flanges are two-hole aligned so bolt holes straddle centerline of piping. Connectors are manufactured in East Syracuse, NY U.S.A.
