Wiper motor air leak

Really Cliff??? Come on. I've seen copper melt in a fire also. BTW, at least nylon won't short out against a bare connection. Also copper work hardens the more you work it.

Oh, just set a dish of mouse snacks near dash so they won't chew the lines. Or....https://www.lowes.com/pd/TOMCAT-4-Count-Wooden-Mouse-Trap/50192375

I am not talking about a fire,I had wire short out in the tunnel where the DOT nylon lines supplied my leveling jacks it was a hell of a mess.Like I said we all do it different I only use it where it is easy to replace and no wires around it

I changed mine over to dot nylon tubing and fittings. I got my tubing and fittings from McMaster Carr. Tubing is 1/4" and you reuse fittings. You can reuse nuts, just get new dot ferrules and reinforcement inserts from them also. Made it much easier to plumb in my pulse wiper control also, which works nicely btw. Just finished it today.

nylon hose uses an internal sleeve ferrule.

i'm sure the OP (and you) know this.
the common copper outer sealing ferule alone often blows out...

Cliff, were those leveling Jack lines air or oil?

They were oil with the oil rated and 3500 lbs nylon hoses pretty standard on hydraulic levelers.LOL every time I weld,grind or cut around that stuff under a bus sure as the sun comes up a piece of slag ,sparks or spatter will burn a hole in it then I have to replace it

Teflon tape/pipe dope - yes or no?

Not talking about the compression fittings here - talking about the fittings that screw into the valves and wiper motors that use threaded ends to make the connection. In plumbing I'd use either Teflon tape or pipe dope. Not sure what the protocol is for DOT air lines so I'm asking.

[luvrbus]

Most shops don't use tape on anything I use the PTFE compound which is liquid Teflon you can buy a tube or a can at NAPA it's a Permatex product

[chessie4905]

That's what I use also. A can or tube lasts a long time, and can be used in household plumbing also. I still use teflon tape in some applications. Like air lines in shop, etc.

Not sure if your valve body is metal or plastic...be careful with any kind of thread sealant if its plastic..Ive seen those break when tightening the fitting, and youre buying a new valve when that happens...fyi...dont ask how I know this
