HYDRAULIC CONNECTION SPECIFICATIONS (CONT’D)
O–ring Flare Fitting (Cont’d)

NOTE: O–ring flare fittings are not recommended in

all applications. Use the standard flare fittings
in these applications.

Do not use a O–ring flare fitting when a copper bonnet
orifice is used. When tightened the connection at the
bonnet may distort the flare face and prevent it from
sealing.

Use a standard flare fitting (Item 1) [A] as shown.

When a O–ring flare fitting is used as a straight thread port
adapter the O–ring flare face is not used to seal. The
O–ring may come off the fitting and enter the system.

Always remove the O–ring (Item 1) [B] from the flare
face as shown.

An O–ring (Item 2) [B] is added to the flat boss of the fitting
to seal the connection in this application.
