How Jet Swet Pipe Seal Tools Work
A Jet Swet tool seals a live water pipe internally using an expanding rubber head attached to a stainless-steel shaft. Once inserted and tightened, the seal temporarily stops flow and pressure, letting you cut, solder, or replace fittings without draining the system. When the job is done, the tool is released and withdrawn, leaving the pipe ready for reassembly.
Typical working pressure is up to 5 bar, making it suitable for most domestic and light commercial plumbing systems. Jet Swet® tools can be used on copper, steel, and some plastic pipe types - always check compatibility before use.
When To Use a Pipe Seal Tool
Pipe seal tools are most useful when:
-
You need to replace an isolation valve or section of pipe without full drain-down.
-
You’re working on a pressurised system and need a quick, safe stop.
-
You want to save time on maintenance in buildings where water shutdown isn’t practical.
They’re a practical addition to any plumber’s kit, helping reduce disruption in occupied properties or commercial premises.
