Customer Reviews (4.8 / 5 · 5 reviews)

Avery ★★★★★

The 70 durometer hardness is perfect for my hydraulic fittings—not too soft, not too stiff. Came neatly packed in a labeled bag so I didn’t have to guess which size was which.

Thomas M. ★★★★★

First time using the dash 424 size, and these fit perfectly in a fuel line repair I needed to do. The 70 durometer is firm enough to hold pressure but still easy to press into place. Will definitely order again when I need more.

Abigail ★★★★★

The 70 durometer on these AS568-424 o-rings feels just right—firm enough for a good seal but not stiff to install. Fit the piston perfectly on my hydraulic cylinder. Glad I grabbed the 40-pack for future projects too.
