The 4-bolt split fange (or full
fange) ftting is used worldwide
for connecting high-pressure
hoses typically to pumps, motors
and cylinders, where the hose
assemblies are subjected to
large pressure loadings.
The sealing mechanism is
through compression of the
O-ring in the face of the fange
head against the surface of the
port/connection.
The fange fttings are gener-
ally separated into two pressure
classes referred to as
3000 psi (SFL) or 6000 psi
(SFS).
ISO 12151-3 refers to the fange
fttings as code 61 for the 3000
psi and code 62 for the 6000 psi.
In addition to these fanges,
customer-specifc Komatsu
®
and
CATERPILLAR
®
fanges can also
be found in the market.

• Standard Code 61 for
3000 to 5000 psi max.,depending on size
• High Pressure Code 62
for 6000 psi max. regardless of size
Although not in the SAE or the
ISO standard the size -10 (5/8)
fange head is gaining popularity.
This fange is often found on
Komatsu equipment or hydrostatic
drives in agricultural machines.
Note: 5000 psi in size -20/-24/-32 with 4A,4F
and 4N fttings and 50H fange halves.
