Q. What other applications can the plugs be used for?
These low cost, lightweight plugs service a wide variety of industrial applications. As “overnight stoppers” they provide a strong barrier in pipeline activities, to prevent foreign bodies entering the line during downtime. Other applications include leak testing of pipework systems, whether commercial, domestic or industrial and sealing holes in castings, tanks and other assemblies. 

Q. What is the maximum working temperature for the Nylon Purge Plugs?
Nylon plugs can be used intermittently up to 120˚C (248˚F) and the natural rubber rings up to 100˚C (212˚F). In continuous use, the nylon should be restricted to 100˚C (212˚F) and the rubber ring to 80˚C (176˚F). For higher temperatures, we manufacture plugs made from steel or aluminium with the rings made from silicone, which can be used continuously up to temperatures of 200˚C (392˚F) and intermittently up to 300˚C (572˚F).

Q. Can the plugs be used as a permanent stopper in pipes?
Depending on the pressure and the internal surface of the pipes, our plugs can be used effectively as a permanent stopper. The wings can be cropped to prevent tampering. The inside of the pipe should be clean and free from debris at the sealing point.

The Plugs are available individually or in Kits to suit Domestic Plumbers, Automotive Radiator Repair Shops and Pool and Spa Maintenance Teams, all of which are available for immediate delivery.
