Plugs for trailer air lines

[skydawg]

Hi,new B61 owner here.I want to remove the trailer air lines from the junction behind the cab.Can anyone tell me the size/thread plugs I`ll need? I`m guessing this is an industry standard size. Thanks.

Likely 1/2" pipe.  It's all std stuff.

For a simple check, if the Outside diameter of the thread fitting is 3/4", its 1/2" pipe.  Pipe dimensions go by the INSIDEof the pipe, so it's like 1/4" bigger then the actual size.

So a 3/4" pipe is about 1" in diameter, and so on.

Thanks.Oddly,when removing,a 15/16 wrench on the flats was too small,a 1" was too big,a 23mm fit perfectly.Would there be  a metric  version of these fittings?

Thats even odder, 24 mm is virtually the same size as 15/16

23 mm is just a little bit bigger than 7/8

Was there paint, rust, corrosion  or other crap on the fitting or was it worn away to a smaller size?

Also if you can find everything you need ordinarily at Home Depot they carry all kinds of different sizes good luck…. Bob

I was not referring to the wrench size.  I was noting the actual thread size.  A tape measure is more then close enough to guess.  It is 1/4" steps in sizes so you can eye that close enough.

When they make pipe fittings, they don't size the hex to a certain wrench...they figure you will use a pipe wrench or crescent anyway.

I took the fitting to a local plumber shop,he fixed me up w/ the plugs.Thanks.
