Test-Tite Kap-On combination test caps are an effective and economical solution for testing DWV (drain, waste and vent) systems. Choose from two models - one fits 1-1/2 and 2 in piping, while the other fits 3 and 4 in piping. These moderate pressure test caps can be solvent-welded on either PVC or ABS pipes and are higher rated than plug-on test caps. Once installed, the caps can effectively test systems with up to 30 ft of water or 12 psig.
