Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic system specialist. Before assembly, depressurize the hydraulic system completely and verify all stored energy has been relieved. Use a calibrated torque wrench and the appropriate open-end wrench on the 1-1/8 inch hex to tighten to the fitting manufacturer's specified procedure without over-torquing the JIC flare seat. Inspect the flare seat and threads for damage before assembly, and replace if any deformation is present.
