Onnline OPK plug for tightness tests 25x2.5 and 26x3 red = 5 pieces CFZ292

The plugs are used to blank off the Pex/Al/PEX and PERT/Al/PERT pipes when conducting leak tests under water or air pressure. They protect installations against the ingress of construction debris. They also work well when passing pipes through wall culverts.
