Anderson Metals - 07046-0812 Brass Garden Hose Swivel Fitting, Connector, 1/2" Barb x 3/4" Female Hose

These are solid brass and will, I believe, last me the rest of my life. I compare these brass fixtures to aluminum repair parts that I had bought at Home Depot last October (2014). I did not like aluminum but HD no longer carried brass. Silly me: I should have waited and searched to buy brass fittings on Amazon instead of the aluminum ones (which were not low cost too boot). Well, from last October to the following March, the aluminum fittings had corroded and essentially "welded" themselves to my brass hose bibs and good thing I checked and removed them when I did as it was very difficult to get them off after only a few months. I checked and sure enough the same sort of thing happened with EVERY aluminum fitting I had bought, including hose repair parts AND quick disconnect couplings that I had on 6 different hoses !!! The aluminum fitting (a few months old) were all removed and GIVEN away (to charity). Here's what happened: the dissimilar metals involved (i.e. the aluminum fixtures and the brass hose parts) when situated in a conductive medium (hard water) created a "galvanic" effect where molecules from one metal type (aluminum) migrated to the other metal - brass, just like a metal plating process. The effect of the molecular migration was to pit and corrode the aluminum parts which became "welded" to the brass parts. The only way to avoid this sort of thing is to use metals of similar nature. A scale known as the Electromotive Series ranks the electrical "distance" of metal chemistry and those that are distant from each other on the scale, have an electrical potential difference that facilitates the galvanic plating mentioned above. By using brass against brass, (instead of aluminum against brass) the electrical distance is brought close to zero and so no plating effect will occur. You know, there is an old saying I heard once and it has stuck with me over the years. I don't know who to credit but it goes something like this: "The bitterness of poor quality remains long after the sweetness of low price is forgotten."These solid brass fixtures may cost a little more but finding them on a store shelf has become more difficult. If I had bought brass to begin with, I would not have wasted what I spent on the aluminum fittings. I feel I will not need to replace these brass items probably for the rest of my life. Yes you WILL need to supply your own 2 cent washer, and yes the outer ring is knurled (not hexagonal) but you may never have to replace the solid brass fixtures again. I would suggest applying a small amount of appropriate lubricant when you assemble these to other (brass) parts, and live happily ever after.

I bought a pair of these to make both a disconnect and small extension for the hose an my 12v pump sprayer. One was perfect and had no problems holding at 65psi static. The other either leaked or fell apart - see first photo. The diameter of the hole outer fitting (hose end) was consistent and .7735in. The diameter of the mating part of the barbed end was inconsistent between .7720in and .7740in. The second photo isn't that great but you can see how it pops out.I have e-mailed the seller for a replacement and will report the results as we work this out.Replaced with no problem. Didn't need to return the bad one. Rating upgraded.

As others have stated, the gasket is not included. I just stole the one from my garden hose and replaced when I was done. I bought this to create a no solder wort chiller and it worked very well. I slipped two clamps onto the clear vinyl tubing, slid the tubing onto this adapter and screwed down the clamps. It created a water tight seal around the vinyl tubing good enough for the pressures used in cooling wort (the grain and hops steeped water used to make beer). However there was a small leak (dripping) where this fitting connected to my hose to faucet adapter. The dripping wasn't a concern for me since it was minimal and over the sink. If you need a completely watertight seal, don't get this fitting. I suggest one that doesn't swivel.Here's what you need to make your own wort chiller.3/8" barb to 3/4" female hose fitting. This one is fine and is currently the cheapest on Amazon. They are $9 at my local hardware store. Hose Clamp  - A 10 pack is sufficient. You can buy these for about $0.90 each at the hardware store but I ended up using 8, so I'm glad I got the 10 pack. These are quality stainless clasps.2x Watts SVIG10 Pre-Cut 1/2-Inch Diameter by 3/8-Inch Clear Vinyl Tubing, 10-Foot Length  - I bought two because my stove is 6 ft from my sink faucet. If your sink and stove are closer, you might be able to just cut one in half. However, make sure you are measuring to the top of your pot and leaving some wiggle room. You don't want your plastic tubing to be pinched. Mueller/ B&K UT06025 General-Purpose Utility Grade Copper Tubing Coil  This is the most expensive part. Be very careful when bending, and always use the tube bender. If it gets kinked and you try to unbend it, it will create a hole and you'll need a new copper tube. General Tools 100-3/8 Tubing Bender for 3/8" Tube Size (OD)  - You can't make it without this, you'll kink and ruin your copper tubing. LDR 500 2050 Aerator Adapter, Faucet to Hose to Aerator  - or any faucet to hose adapter. I happened to already have one that I picked up from the hardware store for about $3 a while back. If you get the dual thread kind, you don't have to worry about sizing. However, most US faucets are 15/16" try that first if you aren't sure, or remove your aerator and measure.I purchased most of these items from Deerso and the brass fitting from Amazon. The total came to $46.05 excluding the faucet adapter, which I already owned. You can buy a wort chiller with tubing and this garden to 3/8" tubing adapter for about $50, but you may have to add more clamps. I needed two clamps on each hose connection on mine. In the end I decided to make my own and I got a nice wort chiller perfectly sized for my pot at the exact depth I wanted and the hose connections external to the pot in case of drips. However, if you don't have the time or interest, buying a wort chiller pre-made isn't that much more expensive than the parts. Just make sure any wort chiller you purchase includes the vinyl tubing and this adapter. They are a significant portion of the total cost.

Repaired my ten-year-old $100 Teknor Apex water hose. NO LEAKS!

works as described

This is being used to connect a huge water tank to our RV when being used on the north forty. The part is well made and easy to connect 3/4” garden hose to s 1/2” RV line.

After trying several new compression fittings to attach my .62” OD and finding them leaking (old ones worked fine!), I decided to go a different route with this brass barbed female fitting with 1/2” barb. Because of size and material differences, you need two additional items to make this leak free: a 5/8” hose clamp and a tube of e6000. Dry fit everything so you know it will work. .62” OD tubing will slide over the barb, but tightening the hose clamp will not be sufficient because this pipe is rigid compared to rubber hose. So, smear barb liberally with e6000 and reassemble, tighten clamp and wipe excess glue off. Allow to dry 48 hours before using so glue sets up completely. The glue in this case is more of a liquid gasket that makes connection water tight. I always disconnect during freezing temperatures and so far so good.

Extreme leakage between the barb and the Swivel Female Coupling. Junk.
