Need source for relief valve, reducing valves and flat faced couplers

    On Wednesday I'm going to get a nice 7 ft plow balde for my 252 CAT. I know I'm going to have to replace the hoses and i thought that while I'm doing that I should get a relief valve and a couple of reducing valves in addition to the flat face couplers that I'll need.
    The problem is that I live in the boonies and don't have convenient acccess to that stuff so I'm wondering if anyone can provide me with an online source.

    BTW, what size hose should I use?

    Here's the cross-over relief valve that I have used with good results:

    (Sorry, it's the DRV-4HH)

    As for the flow restrictors, they are very simple fittings that should be available at nearly any implement dealer. I've always drilled them slightly larger, to 1/16" orifice. You may be able to find adjustable restrictors online as well, but they're really overkill for what you need.

    The hoses can be 1/4" more than likely, but match whatever is currently coming off of the plow rams, and convert up to 1/2" for the couplers.

    Sorry, no online source for those either. Every implement/equipment dealer should ave them as well. I'm sure they could ship the to your door in most cases.
