Ruby ★★★★★

Just got these square profile o-rings for a high-temp pump rebuild, and they fit perfectly with the 0.299" ID. The viton material feels substantial and should easily handle the 400°F rating I need.

Edward ★★★★★

Swapped out some old standard o-rings with these Viton FKM ones for a heat application, and they've held up perfectly under sustained 350°F. The square profile seated much tighter than I expected, definitely worth the upgrade for that temperature range.

Robert J. ★★★★★

Needed a square-profile seal for a high-temp application and these AS568-109s fit the bill perfectly. The Viton material handles the 400°F operating environment without any issue, and the 250-pack gives me plenty of spares for future repairs.
