    Pipe Stoppers: Medium Pressure Applications

    Pipe Stoppers - the MP Series

    M.P. Series test plugs and pipe stoppers are guaranteed to perform at the (specified) pressures common in the water supply industry, water treatment, and industrial markets (up to 250 psi depending on pipe diameter).

    These pipe stoppers offer a cost effective means of conducting tests, or isolating line sections at any interval or stage of construction. This feature is extremely useful where long runs between valves can occur, and where the ability to pull an immediate test after negotiating difficult angles, wall cavities, (elbows), or terrain, can be very reassuring.

    See Our Medium Pressure Pipe Stoppers Chart

    M.P. plugs and pipe stoppers can be the simple solution to many problems where static head, line pressure boosting, or test specifications present pressure conditions which fall into the M.P. test range.
