37o JIC
37o seat angles are commonly used on medium and
high-pressure lines on heavy equipment to join
hydraulic hose assemblies to hydraulic system
components
Pipe Thread
In the SAE system, the sold male pipe thread fitting has
tapered threads and a 30o seat. The tapered threads
are used to create an interference seal when screwed
into a solid female port. The 30o seat is used to create
the seal with a swivel female pipe's 30o seat.
SAE Oring
In the Boss design, straight threads make the
connection while a rubber oring makes the seal. The
threads pull the fitting against the port which flattens
the ring and forms a seal that is excellent for high
pressure applications.
Oring Face Seal
In the Flat Face Oring Seal (FFOR) a seal is made when
the oring in the male contacts the flat face on the
female.
SAE Flange
Oring Flanges solved the problem of making large
diameter, high pressure connections without having to
use an extrememly large wrench. The port is bored
with a center outlet surrounded by a smooth flat face
which has four tapped holes and four mounting bolts
that tighten down onto flange clamps.
BSPP
British Standard Pipe Parallel Thread. BSP is the most
popular thread end in Great Britain. The seal on the port
is made with an oring or a soft metal washer on the
male. The BSPP connector is similar to, but not
interchangeable with our FPX. The thread pitch is
different in most sizes, and the thread angle is 55o
instead of the 60o angle found on NPSM threads
BSPT
British Standard Pipe Tapered Thread. The BSPT
connector is similar to but not interchangeable with our
MP. The thread pitch is different in most cases, and the
thread angle is 55o instead of the 60o angle found on
NPTF threads. Neither the British parallel pipe or the
British tapered pipe has true metric threads, although
many people find these threads “foreign” and conclude
they must be “metric.”
JIS
Japanese Industrial Standard threads. This coupling
looks similar to our MJ and FJX fittings. There are two
major differences - the threads are BSP and the seat
angle is only 30o instead of 37o .
KOMATSU
This fitting looks similar to the JIS fittings. The major
difference: Metric Threads, not BSP.
DIN
German DIN is the most common "metric fitting", with
threads and an inverted flare (either 12o or 30o ).
Available in light and heavy series. MM (standpipe
fittings) is also common. It is machined tubing on one
end instead of threads. Used with a metric nut and
sleeve to made with the same metric connectors as the
swivels.
