Natalie ★★★★★

Finally found a reliable source for this odd Dash 231 size—the 2.609" ID fits my pump housing perfectly without any binding. Handles the hot coolant cycles in my system just fine so far, and the pack of 100 means I've got spares for years.

Evelyn ★★★★★

Finally, a 2.609" ID o-ring that actually seals my hydraulic cylinder without leaking—the 70 durometer gives it just the right firmness. I've already used a few in a high-temp application and they held up perfectly.

John ★★★★★

The -65°F to +300°F temperature range is exactly what I needed for my outdoor hydraulic fittings. These 2.609" ID rings fit perfectly and feel properly dense at 70 durometer.
