VU4 NPT Plug Kit

$27.95

AccuAir VU4 NPT plug kit for classic truck air ride builds, six 1/4 NPT plugs that cap the unused ports on the VU4 four-corner valve manifold for a leak-free system.

  • Correct 1/4 NPT thread - cut for the VU4 body rather than close enough from a parts drawer.
  • Six in the kit - enough to cap the ports a normal four corner build leaves open.
  • Stops a phantom leak - a badly sealed port reads exactly like a bag leak and costs a weekend to find.
  • Protects the aluminum - a plug sized for the port does not split the boss the way an oversized substitute will.

Install Level: Easy

For the AccuAir VU4 manifold only.
