Timothy L. ★★★★★

The square profile on these o-rings really grabs hold in the groove, and the Viton material feels tough enough for high-heat applications. I used them to seal a valve cover gasket and haven't seen a single drip yet—definitely worth buying a pack.

Eva ★★★★★

Needed to replace a leaky hydraulic seal on a log splitter, and these square-profile Viton o-rings held up perfectly under the 350°F heat from the oil. The 70 durometer is firm enough to seat without being a struggle to install, and the whole pack came in handy for spares.

Joshua ★★★★★

Finally found square-profile o-rings that actually stay put in a high-temp hydraulic fitting I’ve been fighting with for months. The 70 durometer Viton feels noticeably tougher than the standard Buna-N ones I used before, and they slide into the groove without binding.
