PPR Threaded Plug Pipe Fitting

PPR Threaded Plug Pipe Fitting is a small fitting used to seal an unused threaded outlet — typically the branch of a threaded tee, a spare port on a manifold, or a threaded valve outlet that is not currently connected to anything. Unlike the fused PPR end cap, the threaded plug simply screws into the threaded port, which means it can be removed again later if that connection point needs to be used.
Because it is a threaded component rather than a fused one, the plug is generally a smaller, simpler part than most other fittings in the range, but it serves an important practical function: keeping a system pressure-tight at points where a connection has been planned for but not yet made, or where a fitting has more outlets than are currently in use.
