3/8" DOT/PTC Plastic Plug

$7.95

3/8-inch DOT push-to-connect plastic plug for classic truck air ride builds, blanking an unused 3/8-inch PTC port with no tools so the system holds pressure.

  • Closes a port properly - a blanked port stays blanked rather than weeping past a makeshift fix.
  • No thread; no sealant - it pushes in like a line and seals the same way.
  • Kit-matched - the same plug Accuair packs inside its systems.
  • Serviceable - pull it later when the build grows a corner or a sensor.
  • Cheap spare - the part that goes missing on the bench costs eight dollars to replace.

Install Level: Easy

SKU: AA-3653
