SAE J514 37° FLARE (JIC)
(Society of
Automative Engineers) Often referred to as
37° JIC, this connection is quite common in
fluid power systems. SAE specifies a 37°
angle flare or seat be used with high pressure
hydraulic tubing. These are commonly known
as JIC (Joint Industrial Congress) couplings.
Both the male and female halves of the connections
have 37° seats. The JIC 37° flare
male mates with a JIC female only. The JIC
female has straight threads and a 37° flare
seat. The seal is made when a line contact is
established between the male flare and the
female cone seat. The threads hold the connection
mechanically.
THREAD NOMENCLATURE
SAE J514 STRAIGHT THREAD O-RING BOSS
This port connection is recommended by the NPFA
for optimum leakage control in medium and high pressure
hydraulic systems. The male connector has a straight thread and
an O-ring. The O-ring boss male mates with an O-ring boss female
only. The female is usually found on ports. The female port has a
straight thread, a machined surface and a chamfer to accept the
O-ring. The seal takes place by compressing the O-ring into the
chamfer. The threads hold the connection mechanically.
THREAD NOMENCLATURE
THORBURN “O” SEAL SAE J1453 O-RING FACE SEAL
This connection offers the very best leakage control
available today. The male connector has a straight thread and an
O-ring resting in the O-ring groove in the face. The solid male O-ring
face seal fitting will mate with a swivel female O-ring face seal fitting
only. The female has a straight thread and a machined flat face.
The seal occurs by compressing the O-ring onto the flat face of
the female. The threads hold the connection mechanically.
