3/8" DOT/PTC - 3/8" NPT Straight

The fitting you will need most of. Three eighths NPT is the thread on most air spring ports and a lot of tank bungs. Three eighths DOT is the line nearly every modern air system runs. This straight is the joint between them; and it is the one you will fit more of than anything else in the build. Thread in; seal the taper; push the tube home. No adapters stacked; no reducers; no extra leak paths. It is the same straight that ships inside Accuair systems - so a fitting cracked on install or lost in a box does not become a week of waiting. Eleven dollars. Buy a spare while you are here.

  • The most common joint on the truck - 3/8 inch NPT port to 3/8 inch DOT line without an adapter stack.
  • Straight through - no elbow means no turn to restrict flow at a spring port.
  • Push-to-connect line side - service without cutting the tube.
  • Kit-matched part - the straight Accuair ships inside its own systems.
  • Eleven dollars - the cheapest way to keep an install moving.
