Review: Try to stay away - I bought this to put in my RV because the current plastic one started to leak, I figured the brass would hold up longer since this is located in a hard to get to spot. Received item was used and abused! First it had a 1/2” nipple that is not part of the item. Threads on nipple showed that it had been used along with thread sealant.
Review: Worked fine on a obsolete Bidet - I'm glad you can still get this part. It was part of the external plumbing for a 25 yr old American Standard Bidet. Looked just like the old one. Worked just fine.
