Charlotte ★★★★★

I've been using these for a few plumbing repairs and the 70 durometer feels firm but still seals nicely against the fittings. The temperature range is a plus since my outdoor setup sees some cold winters.

Sofia ★★★★★

The dash 436 size fits perfectly in my rebuild kit, and the 70 durometer feels firm without being brittle. I like that these can handle up to 250°F, which is more than enough for my hydraulic repair job.

Claire ★★★★★

I've been through a few packs of these AS568-436s for a hydraulic rebuild and the -40°F to +250°F range gave me peace of mind for the colder months. The 70 durometer is firm enough that they don't squish out of the groove, but they still seated easily with a little lubricant. Thirty-five per pack me
