حلقات O-Ring من Viton FKM بقطر داخلي 0.734" وقطر مقطع 0.139" | AS568-210 | داش 210 | صلابة 90 (200 / عبوة)

I had to swap out some seals in a hydraulic line that sees 350°F and these have held up for two weeks straight without a single leak. The 90 durometer is noticeably firmer than my old ones, which gives me confidence in the fit. A pack of 200 for this price is a steal.

Finally a set of o-rings that actually handles my steam application without drying out after a week. The 90 durometer gives them just the right firmness for a tight seal without being impossible to install.

I needed high-temp o-rings for a pump that keeps hitting 350°F, and these Viton ones handle that range without issue. The 90 durometer feels solid and the 200-count package should last me through several rebuilds.
