Hello! I would like to know the replacement o-ring size for a nitefinder. I did a search and could not find any information or size. Also I'm not sure if this changes much but I am going to lowes to get the o-ring althow I beleve the sizes should
be the same even if I wen't to another store.

Thanks alot

Wrap a bit of electrical tape around the plunger head in the slot that holds the O-ring in place. It should expand the O.D. of the O-ring, instant better seal. Just as good as a replacement.

Just take the O-ring to the store with you. Lowes has a size chart laminated on the wall that you can literally press the o-ring up against to compare sizes. I think you're looking for a #12 or #13 O-ring though.

If I had a nitefinder o-ring I would do that but I don't. Thanks for the #s that's exactly what I needed!

The best NF replacement O-Ring that I have found is a #57 Danco O-ring.

I would just like to say that from my experience wrapping a layer of e-tape under the stock o-ring. It is a faster and easier since you don't have to find an exact size, but if you truly want a new o-ring than I suggest going to the hardware store and testing o-rings by putting the o-ring on the plunger and smashing it in the cylinder while hand is on the side of the plunger the barrel would be on. The more resistance you feel on your hand the better seal it will be thus delivering more air.

I know I said "#12 or #13" but I just got home from work and the # I actually use is #14.

Danco #57 is 1" OD, 13/16" ID. The #14 is 15/16"OD, 3/4 (12/16)" ID. The #57 might be better, but the #14 works just fine and is a little snugger.

Sorry for the mis-information.
