Wrenches

For your convenience, we offer wrenches in three standard sizes. You will need two A-304 wrenches to tighten most nuts into unions (for unions 1593 and U-352, you need one A-304 and one A-320 wrench).

The Rheodyne wrench is slotted to fit over 1/16" and 1/8" OD tubing, and has 1/4" and 5/16" ends.

  • Do not use metal fittings in plastic ports, as this can damage the port
