I know there has been a lot written lately on the "right" air bag fittings to use with your GMC air lines.

Before there was such a thing as the GMCnet with its great advice, back about 1984, I decided to do something about my leaking plastic fittings.

I went to the hardware store and bought some 1/4" brass compression fittings in straight and in 90 degree and then some nylon "glands" and the little brass inserts such as used on refrigerator ice makers. Those fittings are still working fine on my GMC 26 years later. They haven't leaked nor required replacement so I just haven't bothered to replace them with the Parker or other such fittings.

Once when crossing a bridge north of Boston in 1986 my right airbag suddenly went flat. I got over the bridge and pulled to the curb right in front of a little hardware store. Examination showed that my air line had rubbed on my tire and burned a small hole into it. I went into the hardware store and bought a brass coupling and the inserts and nylon glands and repaired the line. It has been there ever since and, again, I have not seen the need to replace it with a new line.

I still have some spare fittings and inserts and glands in my toolbox just in case.
