Read MoreWill Even Pass Through Small Pipes!
The versatile Pipestoppers® Inflatable Stoppers can be inserted and retracted through small holes and then inflated to full size for stopping operations. They are used to service a wide variety of industrial applications and are available in the following ranges:
Standard Inflatable Stoppers:
Cylindrical Inflatable Stoppers
Spherical Inflatable Stoppers
The Standard Range of Inflatable Pipe Stoppers are available for immediate delivery with sizes ranging from 1 to 96" (25 to 2440 mm).
Cylindrical Inflatable Stoppers will not invert (turn over) inside a pipe when under pressure, because they are longer than their diameter.
Spherical Stoppers are used where the position of the stopper is not important and they can be put at any angle and still make a seal.
Chemical / Heat Resistant Inflatable Stoppers:
PetroChem Inflatable Stoppers
Heat Resistant Inflatable Stoppers
The PetroChem Inflatable Stoppers are identical in appearance and performance to the Standard Inflatable Stoppers, except that the inside inflatable latex part is enclosed in a thin, flexible rubber that is resistant to the petrochemical fluids and vapours.
Heat Resistant Inflatable Covers are available with a performance rating to give protection up to a temperature of 300°C (572°F).
HFT®'s Pipestoppers® most common applications are:
Debris stopping during machining operations
Leak testing of pipework systems in commercial, domestic and industrial applications
Low pressure hydrostatic tests
On-site thermoforming of bends in ducting and conduit materials
Fibre-optic construction projects
Debris and animal barriers for overnight protection of pipelines
Weld purging to isolate volumes in tanks, to minimise gas purging volumes
Plumbing operations

Read MoreAll Sizes and All Shapes
HFT Pipestoppers® Cylindrical and Spherical Inflatable Stoppers are available from 1 to 96" (25 to 2440 mm) diameter.
They are manufactured using a high quality robust latex inner tube and polyurethane impregnated nylon fabric outer cover and are supplied with a length of flexible inflation hose and sealing valve.
Inflatable Stoppers are available with heat resistant covers to protect them against high temperartures.
All HFT Pipestoppers® Inflatable Pipe Stoppers are manufactured with a strong internal inflatable bag made to the required shape and covered in a waterproof sewn polyurethane coated nylon for low friction and to prevent the production of static electricity or accidental sparking.
Heat Resistant Covers
Heat Resistant Covers are available as an accessory for the Standard Cylindrical and Spherical Inflatable Stoppers range for when they are exposed to temperatures of up to 300ºC (572ºF).
These specially designed Covers can endure high temperatures, which protects the Inflatable Stopper, preventing them being damaged or bursting.
The Heat Resistant Covers are reusable time and time again, without losing their heat protecting properties.
HFT Pipestoppers® Heat Resistant Covers are manufactured to suit all sizes within the Standard Inflatable Stoppers range 1 – 96” (25 to 2,440 mm).
These Heat Resistant cover are also identical for use on the chemical resistant inflatable stopped called PetroChem Stoppers.

Frequently Asked Questions
1.0 How do I know when to choose between a Mechanical and an Inflatable Stopper?
HFT Pipestoppers® Inflatable Stoppers can be inserted and retracted through holes smaller than the one to be sealed. They are much less expensive than mechanical stoppers, but are not so suitable for applications requiring the ruggedness and strength of a mechanical stopper.
2.0 How do I prevent the stoppers from being pushed out of the pipe during a pressure test?
It is common to brace the ends of pipes to prevent stoppers sliding out. The Pipestoppers® Division of Huntingdon Fusion Techniques HFT® can provide further data.
3.0 Will your stoppers be suitable for use in petrochemical pipework where there are hydrocarbon liquids and gases present?
The HFT Pipestoppers® Division manufactures special Inflatable Stoppers for the petrochemical industry where long term resistance to chemicals and / or petrochemical oils and vapours is necessary.
