Joywayus 2PCS 1/2" Female 3/4" GHT Male Water Tank Bulkhead Tank Fitting | With Rubber Ring, Soild Brass, Provides Stable And Leakproof Connection, Water Tank Connector

Purchased in Jan 2021 and finally just used it (July 2022) and worked great for the intended purpose. It is a very industrial quality, heavy brass fitting; I was impressed. Two good quality gaskets and a locking "star" washer and brass nut are provided - it does not leak and I only used one gasket on the inside. The threaded side (hole to drill) is 1-1/8" nominal diameter. For my application, I purchased an extra whole house filter (WHF) housing on Amazon for about $50 for the purpose of drilling a hole in the bottom of the "sump" part and installing this fitting. The municipal well water I have is very expensive and very nasty - full of iron and chemicals and is very hard water. You must have a softener and ahead of that, a WHF to catch the "chunks" to protect the softener. I do not cook with or drink this water, except for that plumbed to, and coming out of, the 3-Stage Reverse Osmosis system which is as good as bottled water. This is the main line coming to the house and it is impossible to purge the gunk that builds up ahead of the filter - from the street supply to the filter. Also, cleaning the head of the filter housing of this gunk was impossible. By shutting off the feed and the outfeed of the softener (so I do not blow too much junk into it - would be better to have a shutoff between the filter and softener, but I don't have that yet). Installing this unit with a hose then turning on and off the supply (outfeed of softener closed) to purge. You can see the water comes out looking like black coffee. After about 30 trips to dump the large "pail" in the picture, I finally just ran a long hose to my utility sink and ran it for about 10 minutes until it came out clear. I hope this idea helps someone who has this same issue so they can purge their lines when they change WH filters. BE AWARE the "big blue" housings can have different THREAD TYPES - some are square threads (Google "Acme thread") and others are sharp like a typical bolt thread - they are NOT compatible. ALSO... if you are adding a WHF housing, BEWARE of big box store "low cost" versions - if you look inside they might choke down from 1" to 1/2" and you will lose a lot of flow (drop in water pressure/volume) - you will get a little drop from the filter element (paper/sediment filter). Get a "FULL FLOW" WHF that is full diameter in/out and internal passages. When in doubt, get a real "Big Blue" housing. And, YES! This fitting is awesome! TO BE CLEAR: This housing can NO LONGER BE USED WITH A FILTER - as you can see from drilling for the fitting in the photos - it is STRICTLY for purging the gunk out. You must be careful not to crack the housing; otherwise there is risk of it shattering under pressure and you should ALWAYS slowly increase and decrease pressure with the feed valve. The hole must be perfectly centered and I recommend starting with a step-drill to open it up to the diameter you need. Thanks!

Needed to replace a bulkhead drain on a humidifier. It was plastic, and the threads were starting to strip. This is a quality replacement with good material and fit and finish. Nice that it offers both 3/4 garden hose thread and 1/2 inch FPT on the inside. I guess this is a thing on others, but I didn't know it. I'd recommend highly.

Installed towards lower part of drum and sits perfect for our GHT Spigot. I placed a red arrow pointing to the Bulkhead Fitting. Blends well, was easy to install and certainly does the job. The way we attached this was the following: - Marked center of fitting on barrel with a perma marker - Used a hole-saw bit the same size as fitting to drill out the area - Fine sand paper to clear any burrs so that the fitting gaskets seat well (this is important for the fitting to work as intended) - Put 1 gasket on the bulkhead fitting and dropped it down into the drum. Then rolled the drum around slowly until the fitting fell into the hole cut. - Carefully held the fitting on the outside while installing outer gasket and nut - Finally, gently tightened down with a 10" adjustable wrench Would highly recommend this particular fitting. We will be picking up more.

Good quality, but I am not sure if inside 1/2” thread is actually npt because fitting bottoms out when screwed in l.

I added a drain hose on two of my dehumidifiers. These fittings worked perfectly and were easy to install.

Threads fit harden hose perfectly. I used this to fix a dehumidifier that wasn't draining properly. Drilled a hole in the drain bin about halfway up and installed this bulkhead. Hooked up a half hose to it and good as new.

I bought a rain barrel and a plastic valve broke in a week. I upgraded to this and could be more pleased. A little tricky to install if you can't get inside the barrel, but I made it work. Super strong, doesn't drip, and all of my hoses thread onto it very well. I would highly recommend upgrading to this before you install your rain barrels.

Yes, the soft rubber washer will squeeze out if you over tighten, but it seals so well without much tightening so I don’t see it as a problem.

Works great as a drain spout in our sauna water tank

not a lot of fun getting a good seal.
