Virtually all components that we repair contain seals, and every overhaul warrants their replacement. I try to use original seal kits whenever I can, but it's not always possible (or feasible) due to logistical and/or economic reasons. In such cases, the only viable option is getting the new seals by size from companies specialized in selling seals.
Unique sealing elements, like metal gaskets or seals with special form, profile, or size are, of course, near impossible to get outside of the OEM's network, but common stuff - like o-rings and shaft seals - is easy to source. Sizing the seals takes some time and effort, but in return, you get an instantly available kit that's often significantly cheaper than the OEM's offer, and with a solid seal supplier the quality is never an issue.
So, I decided to start this collection of lists of seals that I use when we don't have the right kit in stock, and I need the seals for "yesterday." Also - commonly used o-rings - like the ones applied in SAE flanges/bosses or ORFS fittings - are much cheaper when you buy them in bulk from the right supplier - I have included these here as well.
Each list will contain a "Copy to Clipboard" button - for copy-pasting selected lists in an app of your choice.
