This #16 SAE Boss Buna O-ring was the correct replacement for one of our hydraulic fittings. The product description is brief but specific, which is really all I need for a maintenance item like this. It installed cleanly and solved the immediate sealing issue without any trimming or guesswork. At forty cents, it is an easy part to add as a spare whenever placing an order. I would rather keep extras in stock than lose time over a small seal, and this seems like a dependable option.

I used this on a #16 SAE/O-Ring Boss fitting and it matched what I needed. The Buna material was what I was looking for, and the price is low enough that replacing an old O-ring is an obvious decision instead of trying to reuse one. It is not a complicated product, but accuracy matters, and this one appears to be represented honestly. Four stars only because I cannot say much yet about service life, but fit and initial performance were both good.

There is not much mystery to an O-ring, but getting the right one matters. This #16 replacement fit the Boss fitting I ordered it for and arrived as described. I liked that the listing clearly identified the SAE size rather than making me decode part numbers on my own. For the price, it makes sense to buy several and keep them with the hydraulic service supplies. Based on initial use, I would consider it a solid everyday replacement part.
