Quick connect with no drips. 

Superbly engineered RAMPTECH® Lavatory Rinse/Fill Couplings attach rapidly to any standard 1 inch rinse/fill nipple for a no-drip connection between a ground service vehicle and the aircraft lavatory system during servicing. Open end, quarter turn lock-and-release design provides quick connect and disconnect to enhance speed and efficiency on a busy ramp while positive snap lock assures leak-proof sealing.

Other outstanding features include less pressure drop through the coupler (at 180 ppm the pressure drop is 1 PSI less than the Kaiser/Rockwell Collins coupler). The integrated non-return valve prevents whiplash from the jet starter hose and scuffing during coupler removal, and elastomer protection prevents damage caused by ground contact. Furthermore, a special locking system with 8-quick coupler balls securely engages the aircraft nipple to maintain a positive ASU-aircraft connection.
