Aurora ★★★★★

Ordered the bulk pack mostly out of convenience, but I'm genuinely impressed with the quality control—all 600 rings measured true to the 0.299" ID and the 70 durometer feels supple yet firm under my fingers. They handled a hot water line test at 200°F without a hint of swelling, which gives me confi

Aurora ★★★★★

These o-rings fit perfectly in the SAE connections I'm rebuilding, and the 70-durometer material feels solid without being too stiff. The 600-count package is great value for a full set of spares.
