HKS Oil Feedthrough

› 2 versions eligible (standard + XL)
› 5 channels with up to 500l/min
› Optional power rotary feedthrough
› Up to 350 bar operating pressure

With the extra large HKS oil feedthrough, connected hydraulic tools are supplied with a flow rate of up to
500l/min oil (pressure difference Δp = 10 bar, (HLP 46 30 °C)).


Only the HKS oil feedthrough can get the flow rate supplied by your carrier device to your attachment at the lowest pressure difference. This feature enables your tools to operate at full capacity.
Don’t make compromises – put your trust in HKS products.

The unique design and special manufacturing process allow for particularly large channels for greater passage and a low efficiency loss rate. The individual flow rates can be flexibly distributed using multiple connectors. The piping can therefore be optimally adjusted and implemented to suit your carrier device.


With 5 oil channels available (2 for quick coupler, 2 for work unit, 1 for drain line) and a current power rotary feedthrough.
Special solutions for 3, 6 or 7 channels and more on request!
