William T. ★★★★★

The high-temp rating up to 400°F meant I could finally seal my oven door properly, and they fit the groove perfectly on the first try.

Matthew ★★★★★

The -15°F lower limit is what sold me, since my equipment sits outside in Michigan winters. These Viton rings slipped on without any stretching fuss, and the 75 durometer feel is firm but not brittle. Packed neatly, no shipping grease mess either.

Matthew ★★★★★

These seals hit the 400°F spec dead-on, which is exactly why I grabbed them for a hot oil line at work. The 75 durometer feels stiff enough for the groove without being a pain to seat, and the 28-count pack means I have spares on the shelf.
