Replacing Caterpillar® 6000 PSI Flange Fittings with
SAE Code 62 Flange Fittings and Parker “Caterpillar®” Style Flange Fittings
Caterpillar® has a proprietary 6000 PSI hydraulic
fange ftting for use on their equipment. This ftting
is similar to the SAE Code 62 hydraulic fange (SAE
J518). Flange diameters and bolt hole spacing are the
same. The Caterpillar® fange head is thicker (.560”
in all sizes) and the confguration and location of the
O-ring groove is different, requiring the use of a special
O-ring.
The Caterpillar® 6000 PSI fange ftting can be re-
placed with a Parker “Caterpillar®” style fange ftting
such as the 1XA78 using the existing Caterpillar®
fange halves and bolts. In this case the XARG O-ring
would be used. The ftting could also be replaced with
a standard Code 62 fange ftting such as the 16A78.
In this case use HFH fange halves or the HFHFHK kit
with the standard SAE O-ring (711510).
Do not use the Caterpillar® 6000 PSI split fange halves
on SAE Code 62 fange fttings or SAE Code 62 fange
halves on Caterpillar® 6000 PSI fange fttings.
