Great 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 move 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.
