Installation Instructions:
  • Cut tubing squarely and clean tube end thoroughly to remove burrs.
  • Insert the tubing into the assembly making sure the tubing seats firm against the shoulder of the body and the nut is finger tight.

Safety Guidelines:
  • Never connect, disconnect or remake a fitting with pressure in the system.
  • Make sure all fittings are properly installed.
  • It is not recommended to go beyond the pressure rating of the tubing. Elongation could occur in the tubing, shrinking the wall thickness and cause potential harm.
  • For proper sealing it is recommended that the tubing and fittings be of like material.
  • Always use proper thread lubricant and sealants on tapered pipe threads.
  • Never bleed a system by loosening a fitting.
