1/2 to 3/8 Reducer Faucet Adapter - Compression Brass Pipe Fitting, 3/8 Male to 1/2 Male Supply Line Adapter for RV Kitchen Plumbing, Water Hose Pipe Connector with Rubber Washer, (2 Pack)

These sink adapters worked great, and I ended up buying four of them because they were so reliable. Each one fit perfectly and installed easily with no leaks. It made setting up multiple sinks simple and consistent. Overall, a solid product that I’d definitely buy again. No leaks and easy to put in worth the money

Worked well for RV, metal is great quality, no leaks (I do use teflon too)

Worked great to adapt my new home faucet to an RV plumbing system.

Correct fitting to adapt from an RV, 1/2" NPT on 3/8" tubing to common household faucets 3/8" 'fine thread' not NPT. Package of 2 fittings came with rubber flat washers if needed for your application. Connection jointed tightly and no leaks! New sink and faucet was a nice RV bathroom upgrade.

Exactly what I needed and had zero problems installing. No retailers near me carry these. Only caveat is the 6 day prime shipping time. They shipped out the day they were supposed to be delivered!

My camper faucet broke, purchased a new one from Amazon but didn’t pay attention to the sizing and fittings. Instead of returning the sink I purchased these! Great choice, cheap and fit my new faucet perfectly. So far no leaks pics below are from the broken sink. These were life saver

Used it for my camper and it worked great! Perfect fit. Have not had any issues with leaking. Very easy to install!

This is my second time I ordered these for my in-law outside kitchenette. Good product, thank you!

product arrived missing 2 of the 4 rubber washers

Exactly the part needed

I was looking at different reducers adaptor from an American 3/8 faucet to 1/2, but this was the only one that fits. Amazing and highly recommended!

The male 3/8 inch is sized wrong, it is larger the the female 3/8 inch on Moen faucet connection.
