Special Note:

*A quick way to identify which O-Ring Kit is needed for your valve maintenance is, look at the end of the valve body to see what color the valve plug is.

  • If it's Gray, then you need the Swagelok® O-Ring Kit.
  • If it's Black, then you need the Parker® O-Ring Kit.

Note: An easy way to look up parts for your system, is go to Section 5 of your operations and maintenance manual. If you have one of our newer systems, go to lead drawing of your drawing package located at the end of your manual.

Note: The ordering codes are shown in parentheses and bold letters. Specify these codes when ordering.
