Ive got such an array of fittings that I went to the universal type coupler that fit the 3 most popular styles. Then my son threw in a monkey wrench because the GM dealership he worked for made everyone go to the extra long style so my old 3 in one Miltons didnt work for that. Enter the newest model. CoilHose Pneumatics 5 in 1 with safety shutoff.
This is the cats azz. The shutoff exhausts the residual pressure so hose whip isnt a problem and it fits 5 of the most popular fittings.
