Inflatable Low Profile Stoppers

For applications where insufficient length of pipe is available. Can be installed horizontally or vertically.

Available in any size and shape – round, square or rectangular.



The Inflatable Low Profile Stoppers are widely used for blocking pipe ends to keep gases inside or to keep debris and vermin out. These disc plugs provide an excellent grip in the pipe with an effective all round seal. Low Profile stoppers can fit into a pipe end that may be directly on an elbow or inside a flanged neck.

Each Low Profile Stopper is fitted as standard with a Schrader Valve connected to a 1.2m hose and is easy to inflate by simply connecting to a hand or foot pump or compressor. Deflation of each stopper is carried out by simply depressing the pin inside the Schrader Valve.

These stoppers are manufactured for pipe diameters from 6″ and up. They are also referred to as pancake stoppers or donut stoppers due to their shape.

Four pull tags are located around the circumference of the Low Profile Stopper.  This means rope, pull wires or slings can be attached for retrieval of the deflated system if required.
