Our PP tank connection sets, consisting of a PP Push-In Fitting with EPDM gasket and a hose tail with internal thread nut and EPDM gasket, are designed to provide additional straight or bend hose connections to our water tanks and plastic tanks. The key advantage is that the PP Push-In Fitting can be installed completely from the outside of the tank. It is not necessary to hold it from the inside as is the case with PVC connections. The PP tank connection Sets are therefore ideal for installation in hard-to-reach places or for installation on large volume water & plastic tanks. The EPDM gasket on the PP Push-In Fitting is food grade and provides a very reliable seal; it protrudes only slightly into the tank to ensure good tank drainage.
