4 pack Brass Pipe Fitting，Water pipe adapter, G1/2 inch Female to 3/8 inch Male Reducer Adapter,Compression Fitting for Kitchen Bathroom Faucet, Pipe Connector with Rubber Washer.

As advertised—-did the job necessary! No muss, no fuss! No leakage (with teflon tape, of course!), also matches my other visible hardware. Saved me a trip to the over-priced retailer down the road, for sure! Highly recommend!

High quality brass reducer. I could only find them on Amazon, and at a good price.

What a score on these. When the plumber put the wrong fittings on. I thought for a minute I was gonna need to replace them and start over. After finding these I’m off to my next project after only 12 minutes of my time.

The threads are the right size, but the opening on the 1/2" side does not allow the rubber ring of the dishwasher hose to fit properly. I ended up buying this adapter which did work with my dishwasher hose: https://www.amazon.com/dp/B0B1W9WQL7?psc=1&ref=ppx_yo2ov_dt_b_product_details

Gaskets help prevent leaks. Converts my bathroom sink from 3/8 to 1/2. It's perfect

They were 100% as advertised.

This is the right product to connect comfort valve for recirculating pump for your hot water. It took me multiple attempts to find the right product with right threads on both sides.

The 4 pack contained two good ones: fit perfectly and no leaks. The other two had poorly machined threads, neither of them would screw on properly. The same fittings on the other end that worked with the good ones fail with the bad ones. Too bad, since the good ones are pretty good.

This pipe fitting adapter was the perfect fix to allow me to connect an Ikea Faucet with faucet hose connector size 9/16” x 24UNEF (3/8" female compression fitting) in my RV to the standard 1/2" hoses/water pump. Always nice to be able to upgrade your RV faucets and trying to use Ikea faucets in the past was an issue due to the incompatible hose connector sizing. The adapters were the perfect fix!!!
