IMPORTANT INSTALLATION NOTES:
✔ Confirm direction of air flow before installation—check valve must face correct direction
✔ Use only in-line with 3/8" NPT port systems
✔ Protect threads with safety caps until ready for install
✔ Critical for compressor discharge or reservoir feed lines—use only heavy-duty valves in these locations
✔ Use standard NPT thread sealant and torque guidelines
✔ Repairable using RN10CH kit
