Harper ★★★★★

I needed high-temp o-rings for a steam valve, and these Viton FKM ones handled the 350°F environment without any softening. The 75 durometer feels just right, not too stiff. Fit perfectly into the AS568-129 groove.

William V. ★★★★★

These o-rings arrived well-packaged and the 75 durometer hardness feels just right for my application. The 1.549" inner diameter fit the groove perfectly on the first try, and the Viton material gives me confidence it'll handle the 400°F service range without breaking down.

Charlotte ★★★★★

I needed a reliable high-temp seal for a valve rebuild, and these Viton o-rings fit the bill with that 400°F rating. The 75 durometer feels firm enough to handle pressure without being too stiff to seat.
