2 EATONAerospace Group TF100-119C June 2013 Eaton’s Model 61154 Dry Break Quick Disconnect (QD) supersedes earlier Model 60672-1 and is available for use on all of Eaton’s Carter product line of nozzles, both commercial and military. It also mates all other makes of military nozzles. In addition, an overwing/underwing nozzle interchange adapter is also available. Although as a complete unit Model 61154 is fully interchangeable with Model 60672-1 and many of the internal parts are identical, the male and female connections are not interchangeable with the similar parts of the older unit. Most refueling procedures require that the nozzle screen be checked periodically. With a standard nozzle/hose system, the hose must be drained to accomplish this feat. The use of a dry break instead of the standard QD on the nozzle keeps the fuel in the hose. Only the residual fuel in the nozzle needs to be caught during the inspection. All previous dry break disconnects had several disadvantages, including the need to use a screwdriver to accomplish the disconnect. The separation of the two halves of the unit was a “two-man” job and the seal design prevented the unit from actually swivelling during nozzle connection.

Teflon wear rings also reduce side loading of seal, providing better sealing capability than other designs. • Wear rings prevent metal to metal contact (galling) of male and female halves • Military male half adapter has O-ring groove — expensive gasket not needed • Spring loaded thumb latches lock ball sleeve. No locking screws — no tools required. Either latch will keep sleeve in locked position. Provides two independent locks. • Spring load on sleeve in opposite direction of normal hose drag (won’t accidentally be pulled to the unlocked position) — third lock • Safety clip (formerly Option X, now standard) — fourth lock • Higher strength check valve actuating fork • CRES (stainless steel) ball race rings utilized on male adapter half. Eliminates aluminum bronze male used on older commercial 60672-1 model. • Female inlets available in 2, 2½ and 3-inch NPT and BSPP threads • 40, 60 and 100-mesh screens available • Male outlet adapters available to mate all military D-1/D-2, 60427, 64348, 1½ and 2-inch NPT overwing and closed circuit refueling (CCR) nozzles and 1½ and 2-inch BSPP overwing nozzles Envelope Dimensions Options — Dim. “A” — inches (mm) D, S 8.03 (203.96) F, G, T, U 5.97 (151.64) E, J, R 5.72 (145.29) Dimensions shown in inches (millimeters)
