Hooshing Brass Bulkhead Fitting 1 Inch Male 1 Inch Female Thead Solid Brass Water Tank Connector with Rubber Ring Hose Adapter

Nice quality, works as designed slight issue, the threads are not npt.

Used on low pressure pool system working ok. Little trouble to seal. Gaskets real soft. Don’t know if it would work on high pressure. Would be nice to know exact diameter of hole to drill. I used a hole saw that was close. Maybe could not find that exact diameter drill if had that dimension

I used this for a diesel tank project.The quality is excellent and the threads are smooth and strong.Comes with two flat rubber washers.

The ubber washers are too small. You will def have to buy larger dia washers. And the hex side of the piece has no metal washer. So you'll have to buy a bushing as well. I like the brass being heavy duty but the design is weak. Add rubber washers and a bushing and youre good.

I ordered these in June and could not install them until October. When I installed them they would not seal onto the pipe despite using thread tape, pipe dope, and multiple attempts to get them to tighten down and not drip.I had waited too long and now I can't return this order. The idea of brass bulkhead fittings is great but the thread cut on these is wrong.
