Add on valves

Along similar lines, where can I buy the black fabric sheathing that covers the hydraulic hoses such as in below?.My tractor has none.

The Gersen valve has worked flawlessly for our grapple. We used a restrictor purchased from TSC for 4 bucks. It slowed the grapple down to a point where it could easily be feathered.

I have the W.R. Long valve that I got a few months ago thanks to the great help from TBN posters. It feathers very good with the 1/4" hoses, I forget that it is a electric switch sometimes.

I promised to post about the install and operation, but I have been too busy using my grapple! Maybe later this winter.

You are right about using restictive hoses small enough diameter to "feather" the cylinder....to get "light and and delicate use" of it, but I don't think you can "feather" the electric valve. Unless I'm way off base here, it is either full open or closed. That is it allows fluid passage or not. I was referring to the feathing like on a manual valve that you can open "slightly" ...thereby feather it in that respect. Please correct me if I'm wrong.

The electric valve is either open or closed. You can't feather it like a manual hydraulic spool. However, the the smaller restricted hoses limits fluid flow to accomplish the feathering along with the quickness of the on/off switch. Put 3/8" hoses on the work port side of that electric valve and notice the difference. It'll be like night and day.

OK then, that's what I thought.
As far as changing mine to Ø1/4 hose, I don't think I need to. I figured since I was splitting the flow between 2 grapples and using one Ø3/8 hose to feed both, it would essentially do the same, and indeed it does. There is only .006sq/in difference between splitting the Ø3/8 hose and using the Ø1/4 hose. So for all practical purpose, it acts like it is plumbed with Ø1/4 hose.
