Joywayus 2PCS 1/2" Female 3/4" GHT Male Water Tank Bulkhead Tank Fitting

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!

Excellent quality and good price. Yes, it comes with gaskets that are a little softer but perfect for my low pressure application. I will be buying more as I add more barrels to our rain water system. Garden hose screws right on

Great product and fast service

Great for auxiliary pipe connections to rain barrels. Threaded inside & out. Rust proof brass..

The 1/2" X 3/4" brass tank connector was installed at the base of a 55 gallon drum. I did not want to cut a hole in the top of the drum for access so I used a weighted string to locate the 1" hole I drilled for the fitting. The drum is used to hold water for plants in a greenhouse during the winter months. I needed a screen on the suction side because a RV pump is used to pressurize the irrigation drippers. I tied several knots on the string over each other so there was enough resistance to pull the fitting through 1" hole. Once the nut was snug without over compressing the rubber washer I gave a good tug on the string and it popped right out. Very easy to instal, no leaks when the tank was filled and worth every penny. Five stars IMO.

These have done well. I used them for ports on a water heat exchanger I built for use with a wood stove. They have been exposed to water temperatures up to boiling and haven't had any problems. I screwed up and ordered the wrong ones. I really needed 3/4" GHT fittings rather than NPT, but I had some adapters around that I could use to make them work. I didn't want to wait for the correct parts to be delivered. 5 stars from me, though I am tempted to take one off for value. They are pretty expensive.

Upgraded my rain barrel. Its a fitting and it held water.

Used for a drain in soda dispenser tray. Drilled proper size hole and installed. Used a thread to barb adapter with a vinyl tube down to the floor sink.

Works great as a drain spout in our sauna water tank

So yes the outside thread seems like 1 NPT but it is non tapered and is probably at the outer tolerance of NPT diameter, there for it will not fit in other female NPT metal fittings and may fit in plastic female treads, but I would not thread metal male into plastic female. Did not check the internal treads to verify what they are. The item was returned.

Nice quality, good fit

The fittings are well made. No thread burrs and the male/female threads mate well and are adequately tight.The male and female threads are straight cut so tapered pipe thread fittings with PTFE tape tighten nicely.The rubber washers included are soft and while they may be ok for some installations I made some thick fiber reinforced vibram washers for my installation which is a cooling tank for a big stationary engine.No leaks of 200F glycol in my case.They are a bit pricey up in Canada but worth the $ and would buy again.

Installed it on a garbage bin. It fits 1/2" hose bib perfectly. Perfect for making a DIY rain barrel.
