Daniel Q. ★★★★★

The 90-durometer hardness on these #109 o-rings is exactly what I needed for a high-pressure hydraulic fitting, and the 0.299" inner diameter fit perfectly without any binding. The whole batch of 1200 came uniformly molded, no flash or deformities.

Owen ★★★★★

Just finished resealing a pneumatic cylinder on a press, these O-rings were a perfect fit and held pressure immediately. The 90-durometer hardness gives them a nice, firm feel that should last a long time in this application.

Leo Q. ★★★★★

Used a few of these on a fuel system rebuild—the 90 durometer held up perfectly under pressure. Nice to get a full 1200-count bag so I’ve got spares for the next job.
