ORFS, SAE flange, SAE ORB (o-ring boss) O-rings

These are the seals I order the most, which is why I created this page to make my e-mail orders/quote requests easier to compose. Now, all I need to do is insert the desired quantity, click the respective "copy to clipboard" button, and then paste wherever I need. Super easy. I put the sizes in mm and I also included the respective AS568 codes for easier identification (o-ring resellers seem to appreciate this).

In general, I use shore-90 (maybe 80, when 90 is not available) for pressure connections, and shore-70 for suction lines, NBR (nitrile butadiene rubber - a.k.a. "normal o-rings") or FKM (fluoro rubber, a.k.a "high-temperature o-rings", FPM or VitonĀ®).
