HFT Pipestoppers® Nylon plugs, amongst many other applications, are used internationally as the standard 'Drain Plugs' for testing leak tightness of foul water lines during construction.
HFT Pipestoppers® Nylon plugs have also become hugely accepted as "scupper plugs" in the marine industries because of their lightweight and resistance to sea water corrosion. In addition these are much lower in cost than old fashioned bronze or brass plugs.
Furthermore, the range of sizes make these plugs ideal for a number of other applications in the water and gas industries as well as applications in all other industries where pipes are used or where there are holes to be blocked.
Testing and sealing of all pipes, pipe joints and pipe work assemblies can be done with the Pipestoppers plugs. They can be supplied with a hollow shaft version for screwing on standard hose connections or for using our own fixed nipple caps or the free nipple and cap assemblies that we alsomanufacture.
The 1/2", 3/4" and 1" with solid shafts for greater pressure testing capabilities are stocked as well as 1 1/4", 1 1/2" with hollow shafts for drain pipes.
Other applications include:
Sealing holes in castings, tanks, other assemblies for spraying and blasting to protect the insides. Maintenance and installation of swimming pool and water spa pipework, domestic plumbing and sealing holes in all water craft.
Nylon 6 is an engineered polymer which is resistant to salt water corrosion it is also resistant to many other chemicals. Along with natural rubber rings they provide a high quality leak tight seal in the selected orifice.
- A solid shaft version with five sizes from 0.5" (12mm) up to 1.5" (38mm) and
- A hollow shaft version with eleven sizes from 0.5" to 6" inclusive.
All plugs have:
A central spindle/shaft on which two plates are fitted with a natural rubber tyre (ring) between them, a wing nut on the shaft moving the two plates together compressing the ring and making the seal in the pipe or orifice. The natural rubber sealing rings can be substituted for different rubbers where additional chemical and/or heat resistance is required. Alternative rubber rings options are: Silicone, Nitrile & Viton)
The hollow shaft version with sizes from 0.5 inch to 6 inches allows:
Water or gas can be injected or drained as required.
The Nylon Plugs with the 1/2" hollow shaft are available in sizes 1 1/2", 2", 2 1/2", 3", 3 1/2", 4", 4 1/2", 5" and 6". The shafts are threaded on the outside with a 1/2" BSP thread to accept common watr and gas hose connections.
Optional end caps are available with fixed nipples/nozzles for hose connection or free nipples which can rotate when heavier hoses are used.
