3/4 in. PEX Barb x 3/4 in. Female Brass Sweat Adapter

I've used these several times to as a DIYer. Clean your copper and the adapter, use ample flux and get the joint hotter than normal. Never had a failure.

Used 5 sweat fittings on a hydronic heating system. They were the only fittings that had to be replaced. Solder sticks very poorly and sometimes not at all. Junk

Similar to other reviewers here, I was unable to get solder to stick to these. Doesn't have anything to do with cleaning, prep, or materials (solder, flux, etc) as I used many other fittings in my system (with identical installation) and ONLY these gave me trouble. EVERYONE of these wouldn't work. Too bad. First Sharkbite product I've purchased which I'm not satisfied with. Interestingly enough, these have a larger ID than the other sweat fittings I purchased Most fittings have enough friction on the pipe to stay in place while you sweat them on. These things are just loose enough that they will slide off the pipe.

This is complete garbage Anyone with a little experience with a propane torch can tell you, however, that soldering is never a one-size-fits-all operation, with different jobs requiring different techniques. In particular, soldering brass pipes can be more challenging than soldering copper. Read on to learn why and to learn some tips on how to successfully solder a brass fitting. Brass Fittings Require Higher Temperatures The basic process for joining brass or copper pipes is essentially the same: Clean the pipe ends that you intend to join until they are shiny and free from any burrs or debris. Next, brush on the plumbing flux and push the pipes together. Finally, heat up the fitting using a torch, while dripping liquid solder into the joint to create a secure and water-tight barrier. In 2011 they stopped producing MAPP and now they produce MAPP+ which is 400 degree cooler than MAPP Brass does not solder well, brass is cheaper than copper, right sharkbite manfacturer

[This review was collected as part of a promotion.] I have been sweating and brazing pipe for over 20 years and have never seen anything like this. solder will not stick to these fittings. tried several different flux and solder brands, none worked. Will not buy these again. Sharkbite has a real problem here.

I have had the same issue as many folks here. I had an issue with four of these where the solder would not stick. I am a homeowner but have done thousands of sweating copper pipes and never had an issue like this. The initial three I replaced with other ones and was able to complete. Last one just did yesterday wasting over two hours and a visit to HD was completed only by switching to the threaded SharkBite fitting to a copper threaded fitting that I was able to sweat in less than a minute. I am a bit concerned about the SharkBite fittings left that were soldered that they may start leaking one day, so will need to keep an eye or totally remove all of them.

I went through 6 fittings to finally get one to hold. Tried high heat, low heat and everything else we could think of Have been sweating pipe for years and never ran into a problem like this. That's $35 sitting in the scrap bin that I could have used on something else.
