CPVC Stainless Drop ear to Brass pipe nipple?


Hi,
I noticed the drop CPVC drop ear fittings are now stainless and not brass anymore?

My questions is: Can I use a brass pipe nipple like this and just teflon tape and pipe dope into the stainless?

Or does the 2 different metals cause a problem ?

The all plastic treaded drop ears I feel like will leak over time.CPVC Stainless Drop ear to Brass pipe nipple?-plastic.jpg

I like using the drop ear connectors for stubbing out the brass nipples under vanities and toilets for a firm pipe to attach shutoffs to

Thanks!

The solid CPVC drop ears will tend to crack over time from movement of the tube. Placing stainless and brass together won't cause problems like iron and brass would. Even though they are dissimilar materials, no electrolysis will take place. I prefer using Rector seal than teflon tape as it seems to preclude small drips.

No way would I count on a plastic drop leg!
Use a solid brass one instead.
