Product Description
STAINLESS STEEL SCREWED THREADED PIPE FITTINGS REDUCE COUPLING
A reducing coupling is designed to accept pipes into either end. For example a 25 mm to 20 mm reducing coupling accepts
a 25 mm pipe into one end and 20 mm pipe into the other. A 25mm to 20mm fitting reducer accepts a 20mm pipe into one
end and the other end goes inside a 25mm fitting such as an elbow or coupling or tee
A reducer couplings with threaded NPT ANSI B16.1.20.1, or screw BSPT DIN2999, it is typically used in pump station pipe
work to reduce the size of the suction pipe to match the size of the pump suction end flange.
