Chloe ★★★★★

The 1200-count package means I've got plenty for rebuilding multiple hydraulic systems without reordering. These have been holding up well with hot oil around 200°F in my shop equipment.

Miles C. ★★★★★

The 0.103" cross-section is noticeably thicker than the old worn ones I replaced, so they seat perfectly in the groove. These nitrile rings feel durable and should handle my hydraulic fittings just fine.

Michael V. ★★★★★

I needed a bulk pack of o-rings for some hydraulic fittings and these dash 109s fit the bill perfectly. The -40°F to +250°F temperature range gives me confidence they'll hold up under the hood of my truck.
