Oversize Ports

Oversize NPTF or SAE straight thread ports can be

provided, at an extra charge. For ports one size larger

than standard, welded port bosses which protrude from

the side of the head or cap are supplied. For dimensions,

see drawings and tables below. HV2 Series cylinders

equipped with cushions at the cylinder cap end can

sustain damage to the cushion check valve (cushion

bushing) if excessive oil ow enters the cylinder from the

cap end port. Cylinders which are equipped with cap end

cushions and ordered with one size oversize ports having

hydraulic uid ow exceeding 25 ft./sec. in the line enter-

ing the cap end of the cylinder should be ordered with

a “solid cushion” at cap end. All cylinders ordered with

double oversize ports should always be ordered with a

“solid cushion” at cap end.

Port tapped directly into head and cap.

Oversize NPTF Port Boss Dimensions

Oversize SAE Straight Thread Port Boss Dimensions

Cylinders which are connected to a meter out ow control

with ow entering the cap end of a cylinder provided by an

accumulator may also experience damage to the cushion

bushing due to high instantaneous uid ows. This condi-

tion can be eliminated by using a meter in ow control or

“solid cushions” at cap end.
