I'm installing a rubinet wall mount faucet. The 1/2 inch threaded male (piece which connects to a copper 1/2 inch female piece in the wall) has little teeth or grit made into the threads. I'm thinking this is to allow the piece to get a good hold, tight hold, without having to be seated. Any body got info on this type of thread? Thx

Hi Mr Da nile:

That doesn't sound like any plumbing connection that I know of... ;) Sounds like somethingthat needs to be wire brushed off the threads.

Usually, we use some teflon tape on the threads and then install into the female fitting.

Can you post a picture..

Any body got info on this type of thread?
Hey Mr. Nile,
Chickens and pipe threads share a common trait. Neither one of them has teeth.
Marks most likely correct. You probably got a manufactures defect. Take it back and exchange it or keep it for a conversation piece. Cheers, Tom

Nah guys the threads are supposed to be this way ( would post a pic, but fixture is at job site) if you look closely at the threads there are small (tiny) teeth like things. They are on both the threaded connections. ( this is a wall mount bridge. Connects at through wall at a hot and cold.) this fixtures comes from canada, maybe its some sort of revenge on the canucks part : ) seriously, if you find out what they are called let me know thanks

would post a pic, but fixture is at job site)
That's coool Denile,
I popped over to your job site and took my own picture,(see image).
You're tralking about the spout, correct? Let's figure the threads are there for a reason. What could it possibly be?
Ok! Here's my take on it. You would never see teeth on a thread that has to hold pressure, but just a minute, the threads on a spout don't have to hold pressure. All they have to be is watertight. Let's say you had threads without teeth and you tightened the spout but it tightened up with the spout looking up instead of looking down. Yet when you turned the spout down it was too loose. I think those teeth are there to insure a good grip I you have to back the spout off a tad so it would line up. As with all threads I would apply a few wraps of Teflon tape for insurance but I believe the teeth will still insure a grip. I also believe that this is a special thread for this type of valve se don't look for it in the big box stores soon.
Ya got my best shot; Sorry If I missed the boat. Tom

Hey speed I think your close to why they are teethed. Here's the model # and web site of the actual faucet Rubinet Wall Mount Kitchen Bridge Fuacet 8WRBRVC


Rubinet Faucet Company | Toronto | Canada (http://www.rubinet.com/details.php/29_1699/kitchen/sub)


Oh also the connections are off set ( what tha! ) so for the faucet to be level they have to be tightened to the same position, That's why I think your on spot about position

This reminds me of a T&S commercial sink fuacet(sort of). Can you explain exactly what the teeth look like, where they are located on the thread. If you get a chance to take a pic, I would really appreciate a learning experience. Thanks, Lee.

The threads themselves had small slits so that they were teeth. I called the rubinet people, they said just turn the connection till it gets tight and then turn till you get the position you need, The faucets have 2 connections each, and each connection is offset, so you have to make sure each one is in the same position or the faucet will not line up or be level. Put them in yesterday, what a pain. Took 3 tries to keep them from slight leaks, Hard to seal because of dang teeth!

We thank you for the update. When something new comes along we always like to know how it works out in the field. Regards, Tom
