Customer Reviews (4.8 / 5 · 5 reviews)

Chloe Z. ★★★★★

These are exactly the right size for the hydraulic cylinder rebuild I just finished—the 70 durometer feels plenty firm for the job. The 500-count package will last me for years of repairs.

Samuel ★★★★★

Used these to rebuild a bunch of pneumatic fittings on the line, and the 70 durometer hardness makes them seat perfectly without twisting. The -40°F rating was a plus since our shop floor gets cold in the winter, and all 500 arrived clean and consistent in size.

Harper ★★★★★

The -40°F to +250°F rating is exactly what I needed for a hot oil line in my shop, and the 70 durometer feels firm without being brittle. Cracked open the bag and the cross-section is dead-on 0.103", so they seat flush every time. For 500 of them, this'll last me years.
