3.10.16 Servicing hose A 30-foot pneumatic hose assembly of the size
specified in 3.10.15 shall be provided. The hose shall be provided with a quick-
disconnect fitting for an operating pressure of 3,500 psi and mating with the
.
terminal fitting of the high pressure servicing system mounted onthe control
panel (see 3.15). The cupling shall be two-way shutoff and shall be a Hansen
series 2 HK or equal. It shall be constructed of orrosion-resistant steel. An
c
air chuck which shall fit valve assemblies conforming to MS28889 shall be

during usage, and during stowage. Two servicing valves shall be provided; one
located between the servicing line and the air chuck, and the other located
between the dehydrator outlet and the servicing line to control the flow of air
into the servicing line. A manually operated value for bleeding shall be
provided to relieve the pressure in the servicing line-prior to disconnecting. A
