This nylon RV site sewer cap is a watertight locking unthreaded sewer cap that is hammered in place either above or below grade. It is held secure by 10 internal watertight concentric rings and the UV protective gasket creates a watertight compression seal. Has embossed lettering with the word SEWER and can be padlocked or zip tied for security. Fits Schedule 40 and 80 PVC pipe. For SWB or SW35 thinwall pipe, you will need a 4 x 4 bushing for our RV site sewer cap to fit your pipe. We carry a cast aluminum metal RV sewer cap, internally threaded nylon sewer cap and a foot pedal nylon RV site sewer cap as well. See below for more information.
