►DESCRIPTION

TYPES AVIALABLE:

• Cylindrical used for blocking pipes where access is restricted

• Spherical has less contact area than cylindrical stoppers, and is most suited to applications where access is further limited. Due to its shape the spherical inflatable stopper can be used at any angle

• Square / rectangular has a variety of applications, including in air conditioning ducting and venting

• Doughnut - requires minimal space and is perfectly suited to larger diameter pipes as there is less inflation required

• Sausage - has more contact area between the stopper and the pipe wall enabling it to hold back more pressure

• Heat resistant is made of a specially designed Kevlar and Nomex mix material to withstand temperatures up to 500ºC (932ºF) for applications involving higher temperatures such as pre heating

Holdback pressure - unsupported back pressure is 20% of the inflation pressure

Each inflatable stopper comes with an inflation hose fitted with a Schrader valve enabling inflation with a standard airline, bicycle or foot pump.

Inflatable stoppers are supplied standard with no through tube. Through tubes can be supplied on request at extra cost when the stoppers are required for weld purging applications. When deflated, the inflatable stoppers can be inserted and withdrawn with ease when access is restricted
