Stupid question....

    But I'll ask anyway.

    I am replacing the hoses on my Meyer pump, including changing the fittings at the pump and the angling cylinders. The reason I am replacing the fittings is because I am uppgrading to the larger diameter quick-connects from the smaller ones that came with the 58H pump. My question is this: what should I use on the 1/4" NPT threads? Teflon tape, pipe dope, or nothing? I am thinking that teflon tape in the way to go, but I am not sure. Opinions?

    Pipe dope, teflon tape doesnt break down if it makes it to the pump.

    there are all kinds of opinion's but i like a little carefully applied pipe dope .if your not careful it is to easy to over tighten and crush the fittings or split the boss they are going into .and you can suck tape into the valve's . just my 2 cent's worth .payup

    I use teflon tape but I am very careful when putting it on.

    Never use tape on a hydraulic system. I cant tell you how many times we have had to clean it out of a valve.... Use a Teflon pipe dope, screw the fitting on as far as it will go by hand then one more turn with a wrench. Run the plow and check for leaks if you have a leak go 1/4 turn more and that will usually stop the leak
