Hey All,

I want to buy a few O rings from the local seal shop.
I dont have an old sample ring to take along.

Real OEM specs the ring as 88x3mm.
Does anyone have an spare ring and can let me know if the 88mm is ID or OD.

Thanks
Malcolm(t)

As close as I can measure without it being in a cover for equal support, it measured 88mm id x 3mm thick.

Hi Malcomb....

The question re O-Rings... Every O-Ring has a BS ( British Std. ) Identifier as well as a DIN, Parker and MilSpec Identifier... BUT in the factory, we use the ID and the 'rubber" cross-section diameter to identify the parts. This is because Inspection uses non-contact Laser measurement to assure consistency and to weed out defects. The Laser sees a "black ring: on a white background and does the "math" on the five zones ( first white outside, black shadow, white inside, second black shadow, last white outside ) as they travel single file on a translucent conveyor. This assures that by subtracting the two outside 'whites' and the one inside 'white' that the remainder will be the ID.. So in your case the '88' is the ID and the '3' is the rubber crossection, both of which are nominal values. Rings like this up to 400 mm ID and 30 mm crosssection are routinely scanned at 3600 pieces per minute @ 0.02% reject rates.

More than you wanted to know I'll bet !

Good luck......// Ernie in NH

Thanks for the info.
I'll pick up a few at the local seal shop tomorrow.

I had spoken to our mech guys at work, nobody knew the norms for sizing. Now i can teach them something.
