Not that I have ever run across. You can get 1/4" Uniseals. You might be able to use one of those.

I have some and this is where I got mine.

Okay great, I was look to use it for the return hole, I have a 1/2 for the drain and now I needed another one for the return hole.

You must be working on something really small. That site also sells off size diamond drill bits that you will need if you are looking to install that on a glass tank.

BRS has a 1/4" push connect bulkhead tank adaptor it doesnt have a gasket but a little silicone will seal it.

If I was to use it as a return hole how would I make a nozel and elbow for the front and back of this uniseal? Thank you for the information greatly appreciated!

Are you sure you want 1/4"? That's about the OD size of some airline tubing, or RO tubing. If that is what you need, you can find air line tubing fittings at PetCo or PetSmart. For rigid tubing, you can look on BRS to see if there is something there that fits your needs (in the RO fitting section). Personally, I think that is awfully small for a return line on a 12 gallon tank. I would use 1/2" pvc for the return and 3/4" for the drain.

Best I could come up with for 1/4"

You can get a bulkhead union in 3/8", 1/2" or 5/8" OD from Spectrapure, I use the 3/8" one installed in my ATO container for the DI flush on my UHE RO/DI. The 5/8" might fit the bill.

Okay thanks everyone, I will definitely look up each link. The glass hole is about the size of a quarter

If the hole you are looking for a bulkhead for is "about the size of a quarter," then the bulkhead you are looking for is probably a Â½" - not a Â¼". You could probably throw a 1/4" fitting through the hole for a Â½" bulkhead. If the Â½" doesn't fit, then it is possible that the person that drilled the tank originally didn't use a bulkhead. I have seen some people drill a hole and then just insert a short piece of PVC pipe through the tank and put fittings on both ends. Then they "seal" it with silicone. Definitely not the way to go, but I have seen it done.

If you can't find anything to fit the existing hole, you could also seal off the old hole and drill a new one to accept a Â½" bulkhead in a different location.

Have you maybe tried another brand of Â½" bulkhead? Just grasping at straws here. I am at a loss as to what the original owner could have used in that hole, unless it was another brand of bulkhead, or no bulkhead at all. Strange. Good luck getting this resolved.
