This is our faucet:

The o-rings shown (RP22934) are what we need to replace. The question is this: Must we try to find those specific Delta part numbers, or are these type of o-rings general enough in nature that we might find them at a local big box that's still open tonight?

These look to be one inch (or slightly over) in diameter.

Note: I know this forum is connected with an online store too, but I couldn't find the Delta part numbers on it. Hence the link above. Please don't shoot me.

O-rings are not brand specific. Although finding the right size can be challenging at times. It also helps if you know the rubber type...
There are several.

Usually the faucet information from the Delta site does not raise objections while a competing site that sells faucets would.

Some manufacturers are kind enough to actually list the size and material of the o-rings however delta does not...

O-rings are a commodity, but there are a huge number. Set aside different materials....most faucet o-rings are probably buna-n.

O-rings are a precision seal, much different from a seat or gasket. SO, the ID, the OD, and the cross section ( thickness ) must be very precise.

You could probably take any faucet o-ring into a very well stocked plumbing supply, and the counter guy could match it up. It is much easier to purchase an o-ring ( or set ) as a specific part number for a specific faucet, rather than look for a part that is 29/32"OD, 27/32"ID...etc. But it is not mandatory.

i don't know for sure, but the "O" rings may be part of a rebuild kit.
typically a delta rebuild kit contains seats, springs, "O" rings and a tool.
lube the rings with silicone grease..

They are not brand specific, but they are size specific, and since there are thousands of sizes, buying the OEM o-ring saves you time and effort of trying to match its dimensions.

I'm sure that if you call Delta, they will send you those O rings free.

A little word of caution for anyone buying a new faucet.
Don't buy the off brands at the big do-it-yourself stores.
A bought a house with a leaking faucet that had no manufacturer name on it. I went to home depot, lowes, and a reputable plumbing supply and no one could match up the o-rings.

Buy a name brand!

As stated above, several different types of rubbers/polymers, several different durometers(hardness), and MANY different size combinations are available. If you have the TIME to surf through all these, you can find several places that will sell you 100-1000 o-rings of each size you need. This is wonderful if you are running a faucet rebuild shop, but is really inefficient and costly if you just need to repair 1 or 2 faucets.

Unless you NEED the larger quantities, I suggest you go for the OEM parts. They may seem expensive, but the alternative can be even more costly.

Johnny go to this link [www.mcmaster.com]# and type "O Ring" into the search block...

I guarantee they have your O-Ring.

Finding which one it is may be a challenge though...
