Our plastic fittings/accessories in ½ - 2 inches give you maximum flexibility for additional tank connections with tank connection and other accessories. Use the filter options on the left under "Category" to get an overview of our plastic accessories. We recommend our pre-configured PVC Tank Connection Sets for easy, quick and reliable installation of additional connections accessible through the water tank lid opening. If you require an additional tank connection that is to be installed in a position that is not accessible through the lid opening (e.g. it must be completely screwed on from the outside), use our PP Tank Connection Sets. When assembling your bespoke plastic accessories, always ensure that the fitting has the correct inch size and that the male and female threads of the fitting are compatible.
