self tighting.



Well this got me curious 'cuz I'd always tightened 'em myself so I laid a fittin' on the bench next to a pump I had lyin' aroun' and went in an' had my supper an' when I went back out to the shop they wuz in the same place I left 'em. So I got t' thinkin' maybe I got the self-sealing kind an' not the self tightenin' kind !!!
