These pre-assembled kits bring together both a filter and a pressure regulator, providing you with a complete assembly. The kits use a 150 mesh stainless steel filter screen, a flush cap and a pressure regulator to maintain a consistent 25 or 40 PSI at flows between 0.5 ? 15 GPM. Available in either a ¾” or 1” inlet, both models have a ¾” outlet, ready to be used in all drip irrigation projects.
