Inflatable Pipestoppers

Product catalog summary

Overview: Pipestoppers™ Inflatable Stoppers and Test Plugs are designed to stop the flow of gas or liquid in pipes or ducts, collect debris, and prevent unwanted material or animals from entering. They are available in various formats and sizes ranging from 2" to 80".

Types and Applications:

Standard Cylindrical Stoppers: Ideal for stopping pipes where access is difficult, commonly used for testing new pipes and drains.
Spherical Stoppers: Provide less contact area but are useful when access is limited, can be inserted at any angle.
Square/Rectangular Stoppers: Used in air conditioning systems, air ducting, and venting.

Specifications:

2" to 24" stoppers have a 2m hose length, 8mm ID, 14mm OD, with a plastic valve and 1/4" BSP connection.
26" to 79" stoppers have a 2m hose length, 10mm ID, 14mm OD, with a metal ball valve and 1/4" BSP connection.

Performance Factors: The pressure an Inflatable Stopper can hold depends on the pipe surface, friction resistance, contact area, support, and internal pressure. For example, a 4" stopper inflated to 10 psi can hold back 2.5 psi in a cast iron pipe.

Other Products: Pipestoppers™ also offers expanding pipe plugs, steel expanding plugs, rectangular inflatable stoppers, ATO inflatable stoppers for concrete pipe joints, and special inflatable stoppers for nuclear applications.
