Seal It, Quick, Fast and Easy!
To complete the Pipestoppers® range of nylon and aluminium expanding plugs, Huntingdon Fusion Techniques HFT® also offers Pipestoppers® Steel Plugs and Stoppers in all plug sizes for more arduous duties.
These HFT Pipestoppers® Steel Drain Test Plugs are typically suitable for long immersion in water, for use at higher temperatures or for contact with acidic or alkaline environments for which the nylon, aluminium and inflatable plugs may be unsuitable.

Read MoreLeak Testing, Isolation, Sealing and Stopping
HFT Pipestoppers® Steel Test Plugs and Stoppers can be used for pressure testing and plugging all pipes, pipelines and pipe work fabrications and any other orifices between 2" to 72" (50 to 1800 mm) diameter.
These HFT Pipestoppers® Steel Drain Test Plugs are specifically designed for heavier duty applications such as long immersion in water, for use at higher temperatures or for contact with acidic or alkaline environments for which the nylon, aluminium and inflatable plugs are unsuitable.
Low cost expanding HFT Pipestoppers® Steel Testing Plugs and Stoppers range for sizes up to 6 feet (1800 mm) diameter.
The standard seals are made from natural rubber. Synthetic rubber seals (for example for petrochemical applications) are also available.
Options are:
• Silicone
• Nitrile
• Neoprene
• Viton
HFT Pipestoppers® Steel Test Plugs and Stoppers are available as single plugs as well as double versions for greater sealing capacity and stability inside pipes.
Standard sizes of HFT Pipestoppers® Steel Test Plugs and Stoppers are available for immediate delivery.
All Plugs conform to Quality Standards BS8005 and BS EN752-4 for low pressure testing and sealing of pipes.

Read MoreGreat for Purging of Pipework too!
The HFT Pipestoppers® Steel Test Plugs and Stoppers are extremely easy to use: Merely insert the Plug into the pipe and tighten the wing nut to force the top and bottom plates together, thereby expanding the rubber ring to seal tightly in the pipe.
A patented friction-free washer allows for easy tightening of the wing nut.
The HFT Pipestoppers® Steel Test Plugs and Stoppers are suitable for the more arduous tasks such as:
• Contact with acidic or alkaline environments.
• For long immersion in water.
• Use at higher temperatures.
Where plugs might be required to work close to the top of their pressure range and to hold seals longer than would be the case with single plugs, Huntingdon Fusion Techniques HFT® offers Pipestoppers® Double Length Steel Plugs and Stoppers.
With the HFT Pipestoppers® Double Steel Testing Plugs, the pressure capability of the Plug increases, the double plug preventing tipping (like a 'butterfly' valve) to guarantee the seal. They are more secure at the highest point of their pressure range and give more stability inside the pipework, giving a greater guarantee of the seal.
