Flareless and Flared Fittings.
The MS Flareless Connection.
This connection is being used
extensively on newer model aircraft.
This fitting is designated
primarily for high-pressure gas or liquid systems and for service
where it is subjected to severe vibrations or fluctuating pressures.
This connection retains a seal under these conditions better than any
of the other types.
The MS flareless connection consists of a
connector, sleeve, and nut, as shown in Figure 2-8. The tail on the
sleeve dampens out tube vibrations, preventing fatigue and breakage,
while the spring washer action of the sleeve prevents the nut from
loosening, keeping a better seal.
