Description

Got these 4" steel drain test plugs – 20 in total. They’re used to block pipework and check if it’s air tight. Fits pipes with an internal diameter of 94–108mm, needs a minimum 37.5mm insertion depth. The steel’s zinc-plated so it can handle salt spray for up to 90 hours without rusting. Just a reminder – whoever installs it should make sure they don’t go over 10psi back pressure. These fit pipes 95–108mm ID. I’ve got them ready for collection in usk, Monmouthshire. Each one is £4.50.
