Replace wearing parts on the TeeJet 23120 Series Pressure Regulators with the replacement parts provided in this Repair Kit for TeeJet 23120 Pressure Regulators (23120KIT).
A clear indication that the seats or o-rings are worn in the TeeJet 23120 Pressure Regulator is if you notice your system does not generate enough pressure and all your volume returns to the tank, rather than creating pressure out of your nozzle. This repair kit will solve this problem, as it comes with the guide seat and Viton o-ring for the regulator.
NOTE: TeeJet's repair kit for these 23120 Regulators includes the spring ; however, we do not include it in our repair kit because the spring is not prone to wear as much as the other parts and therefore does not require constant repairing.
