Quickun Plastic Hose Barb Fitting, 1/2" Barb to 1/2" Male Thread White Adapter Union Fitting (Pack of 5)

This is exactly what I needed to attach to the top of a Humidifier Flush device. The threads are the same top to bottom (MIP) and make the seal by contacting the rubber washer at the bottom of other piece. A tapered NPT fitting would pose a risk to split the plastic of the piece I was screwing this into. No leaks no problems. Just be sure this is what you need!

Good product at a good price

They were the wrong size for the filter I purchased from Amazon

Common size for residential garden hoses. Ordered twice now. Simple., No rust. Don't waste your time at Lowe's or home depot, they don't carry it. This is a better price anyway.

Needed this for my water filter, which has a drain valve for each filter housing (have a triple 20” BB while house water filter). Since this will never be a high pressure setup, sealing them isn’t important. Just needed to use this and a hose to prevent splashing to a bucket.

The description claims it is an NPT thread, but it is not. NPT threads are supposed to be tapered so that they tighten and seal as they are threaded in. The thread on these parts is not tapered (see picture). The thread pitch is correct, so it does thread into an NPT female thread, but it does not seal, even with PTFE tape applied.

Great product that did its job as expected

Buyer beware- The description says hose barb to 1/2" male NPT thread. These are NOT NPT. They are straight threads (I suspect BSPP but have not verified). These will thread into a 1/2" female NPT but will not seal. A gasket , o-ring, or similar will be required for these to seal against a mating part. And, in case you're wondering, no amount of the supplied thread tape will fix the issue.
