If you find the 017 to be too tight, the 016 works well for the head too.

Must be very hard to settle on a 'standard' size for the o rings.

The actual measured sizes are all over the board and I am amazed that the O ring industry gets away with this.

I just purchased from Parker, a big manufacturer, a quantity of O rings in 015,016,017 and 019. Half were the orange silicone and the rest standard Nitrile. The cross section varied 0.007" between the silicone and Nitrile. I was amazed.

I was told that metric O-rings hold to their actual dimensions but that the AS568 rings can have variations in both actual vs specified dimensions as well as tolerance "drift". /ubbthreads/images/graemlins/icon3.gif
