O rings

Which O ring goes on first on a Zeirdan boom, yellow dot or plain black ? Thanks

Put the Black "O" Ring on first so it falls into the first groove and then put the Yellow Dot "O" Ring over the first "O" Ring. Coat the "O" Rings with a generous amount of silicone grease, something like Napa 7651346 Sil Glyde silicone grease. When you reinstall the seal case back it off at least one turn, you don't want to have it tight.
