Ask a Question

Did you just spend $100K on a new Cat D-Series machine and try to run high flow only to find out that the dealer didn't throw in a high flow plug?  Here is the solution.  Buy our plug for half of the dealer prices and run your high flow hydraulics on XPS or XHP machines any time you like.


Works great for high flow mowers or any other device that does not require any electrical connections but needs to operate with high flow hydraulics.

  • I have a 2016 cat 259d skid steer but don’t have the the plug will this work on my machine and what else would I need to wire it in? Thank you

    This is a high flow jumper plug.  If your machine is not equipped with a plug, you need to contact a Cat dealer and buy the proper harness for your machine.

  • So do you just plug this in and you're ready to go or does it need to be wired to the machine or attachment?

    Plugs into the machine and tells it that you need to operate HF.  From there, the machine will switch on HF when needed.

  • Will this work for a Cat 906m compact wheel loader? Thank you.

    I would need the page out of your manual showing how it works.  I only work on skid steers and CTL's.

  • Will this work on a 299C

    No.  it says Cat D-Series in the heading.  Some people have bought this item with the understaning that they may need to move the pins since we cannot find anything published as to what they are supposed to be.

  • Highflow plug eight pin for a 262 ?

    If it is an A,B or C series 8 pin plug we currently do not offer a plug because they are so old that most people already have the plugs. If this is whay you need, you can order the plug and just make the jumper yourself.

    If it is a D series - Click this link.

  • I need a connector from 2015 299d2xhp to a older Bradco Dozier blade is this the right on

    This is a high flow connector allowing a D series machine to run high flow attachments.

  • The typical adapter from cat only runs high flow in one direction. Will your run high low in both?

    No.  Most manufacturers only allow High Flow in the forward direction because the return valving bypasses when the pump is running forward so there is little back pressure.  If they allowed you to reverse the flow, then they would have to allow the forward pressure line to become the return to tank line at the same time.  They just don't do it that way so you are stuck running HF in the forward direction.  Cat, Bobcat, Kubota and Takeuchi are a few that I know of that will only allow HF in the forward direction.

  • Is this product in stock and ready to ship after payment is received?

    We have hundreds.  How many do you need?
