Hose Connector Inverted Flares
If the brass inverted flare connectors show need of
replacem ent, proceed as follows:
1. Tap threads into the center hole of the connector with
a 5/16-18 tap.
CAUTION: Do not tap the threads too deep in the
pressure hose connector seat as the tap will bottom
the poppet valve against the housing and damage
it. It is necessary to tap only two or three threads
deep.
2.
Thread a 5/16-18 bolt, with a nut and flat washer
attached, into the tapped hole so that the washer rides against
the face of the port boss and the nut rides against the washer.
3. Hold the bolt from rotating while turning the nut off
the bolt. This will force the washer against the bolt boss and
will back out the bolt, drawing the connector from the
housing. Discard the connector.
4. Clean the housing thoroughly to remove any tapping
chips.
5. Drive the new connector against the housing seat
using Tool J-6217, being careful not to damage either the
connector or housing seat (fig. 3B-51).
