3/8" DOT PTC Union

$10.95

3/8-inch DOT push-to-connect union for classic truck air ride builds, joining two 3/8-inch air lines when a run comes up short or needs a repair splice.

  • Saves a whole run - a short line gets joined instead of replaced end to end.
  • Push to connect - no thread sealant and no tools at the joint.
  • 3/8 inch DOT line - the same size the rest of this fitting family uses.
  • Cheap spare - the fitting you want in the box before you need it on a Sunday.

Install Level: Easy

SKU: AA-3758
