حلقات O من بونا-إن نيتريل مقاس 0.103 بوصة CS × 0.611 بوصة ID | AS568-114 | داش 114 | مقطع مربع | صلابة 70 (800 / عبوة)

The square profile on these o-rings holds a lot better than round ones in our pneumatic fittings—haven't had a single leak since swapping them in. Easy to install with just a pick and they seated perfectly on the first try.

I’ve been using these in hydraulic seals and the square cross-section holds firm under pressure, even at 250°F. The 70 durometer gives just enough flexibility without deforming.

The square profile sits perfectly in the groove without rolling out, and the 70 durometer has just the right firmness for a snug seal. I grabbed the 800-pack knowing I'd use them across several projects, and the sizing is dead-on to the AS568 spec.
