About Dry-Disconnect Fittings
Dry-Disconnect Fittings; also known as Dry-Disconnect-Couplings or Valved-Couplings, contain internal valves operated by coupling a pair of fittings. Neither fuel nor air can pass through the fittings unless the pair is coupled. Using them allows the QuickTank to be removed without spilling fuel. Note: Couplers should be kept clean to prevent leakage.
