1 1/4" UNISEAL Flexible Tank Adapter (Bulkhead) - 2 Pack

I bought a pair of these to use for a homemade fish pond filter. I used a heavy duty Rubbermaid trash can and drilled 2" holes for these 1 1/4 seals. Pushing your pipe through them will be tough- use a bit of liquid dish soap. They are tight, do not leak, and are so much easier than other bulkheads with rubber washers and threaded nuts.

Perfect for the job, thanks

Perfect fit making my homemade biological filter for my pond, works like a charm.

These are fantastic for curved surfaces. We use them on our rainbarrels to great effect. No leaking -- ever!! Super-easy install with no cross-threading issues. Love them!

I turned a 5 gallon bucket into a filter for a "fish tank" and they worked fine. I would recommend either putting something on it to lube the pipe;) ;) or you can put the pipe in before you put it in the hole take the pipe back out put the gaskets the hole and them the pipe will fit easier.

Best economic solution for this application. Very sturdy and might last long long time without UV

Best idea for the application

Did the job it was intended for and as advertised. No complaints.
