Repair 2 check valve outlets on H2O Jet's 94k intensifiers. To work with Flow intensifiers, the spring retainer #192008-1 must be re-used. 2 of those parts plus this kit will replace Flow's #014885-1 to repair both check valve outlets. See kit #392003-2 for parts to completely repair one check valve side - both inlet and outlet - on either Flow or H2O Jet intensifiers.
