Fenco coupling question:

[oldberkeley]

Replacing a kitchen sink. Got a 1 1/2" Fenco flexible coupling to join the old copper drain pipe to some new PVC.

It says to torque to 60 in. lbs.

All I have is a little hand socket driver.

In general, is 60" lbs. snug, tight, very tight, cranked to the max?

Just tight !!.....Don't kill it,,,,,its rubber !!!!!

I've used a number of those. Are you using a shielded or non shield coupling? I would recommend a shielded. I just use a nut driver and snug it up, don't kill it. Think of it this way, 60in lbs is 10lbs on the end of a 6".

 

[oldberkeley]

It's a shielded one.

That's what I've got, a nut driver.

Thanks guys, I'll go for something between snug and tight.

One thing, slightly deburr or chamfer the outside edge of each pipe to make them slide into the coupling easier without tearing. Those have saved me a number of times in a old house with copper pipes.

LOL, you should have seen me this afternoon! Started off with cutting the old copper drain pipe about 6" off the cabinet bottom, looked like ****. Tried again an inch lower, still looked like ****. One more time (can't go much lower), called it "good enough" and filed/deburred like a madman because of what you're saying: afraid of tearing the rubber.
