Sizes available are for pipe bore sizes: Pipestoppers Nylon Pipe Plugs are suitable for a myriad of applications. They are mostly used for weld testing, leak testing of pipework fabrications, weld purging or simply stopping to prevent the ingress of dirt, rodents and other unwanted material. However there are over 100 different applications for these plugs.These plugs are constructed from injection moulded nylon components and rubber rings. They have the advantages of being light, non rusting easy to expand and can be dismantled for cleaning purposes.The grade of nylon chosen is pure nylon 6 which has considerable wear characteristics and makes them stronger and more robust than other plastic plugs.These plugs will provide airtight seals and in tests with plastic pipes are capable of sealing against pressures from 60 psi - 4 bar, to over 100 psi - 7 bar.Effective sealing is simple, insert the plug into a pipe opening and tighten the wing nut clockwise. The rubber ring will expand and provide a positive seal. To remove simply reverse the process. Pressure Rating > Nominal I.D.

Also for ducting and conduit, plastic pipe bending, swimming pools, masking in painting and casting industries and many others. > 2 3 / > 4 " 18 - 24 mm 150* 10*1" 23 - 32 mm 130* 9*1 Applications > 1 / > 4 " 31 - 42 mm 70* 5*1 > 1 / > 2 " 37 - 54 mm 60* 4* > With 10mm BSP threaded waterway: > Nominal I.D.

As working temperature is increased, it can be expected that pressure ratings must be reduced. size="-2">
