ferrules

I don't have any hardware stores near me and Home Depot and Lowes never have plastic ferrules or rings to do compression fittings.
Even the fittings have metal rings.
Besides ordering them is everyone using copper/metal ones now which could eventually cut the pvc/cpvc?
Thank you

Not sure why you are having so much trouble....this is a very common item. The Germantown HD store shows 19 in stock. Have you asked someone to check inventory and search the upper shelves if they aren't on the hanger? If they can't find them, they can do an inventory adjustment so they get an order in.

I wouldn't use the brass sleeves.

Btw...all the inserts are brass..they don't do them in plastic.

I am assuming that you are attempting to use common brass compression fittings on CPVC piping, correct? I would strongly urge you to NOT do that but instead use the solvent-welded CPVC fittings or a Sharkbite fitting.

Oops....missed the PVC/CPVC thing! Agree with Furd.....I'd never use regular compression on those.

SharkBite or glue.

Just to add....If you are connecting the poly faucet/toilet 3/8" lines from stop valves, you cannot use metal ferrules. You must use the nylon ones. Metal ones should be used metal only.

I will ask them to look for them in stock.
I am using cpvc compression fittings so need the nylon ones and thank you.

No, I mis spoke. Only if using the poly lines do you use the nylon ferrules. I shouldn't have said metal ferrules on metal only. CPVC is different than the poly lines. I would use the glue up or sharkbite valves, as well.

compression fitting

I have no metal in my townhouse. Everything is either pvc or cpvc.

Don't glue fittings take about 12 hours before use?

I thought a compression fitting should come with a ferrule or ring and as Gun Guy pointed out these plastic ones should be in the store.

I know a compression fitting has to be visible.

Too sick and old to bend and need to take the path of least resistance.

Thank you for the help.

I'll state it one more time, metallic compression fittings are NOT for use on CPVC piping.

You can purchase a "hot" solvent welding compound (glue) that will harden in a couple of hours or less at room temperatures.

Or you can use Sharkbite fittings. They ARE a bit expensive but they are also very easy to use.

I've never waited more than about 15 min before turning the water back on and never had any issues. That said...most sellers recommend 12-24 hrs...though some cement manufacturers apparently just say several hours for full pressure rating. Since household pressure is much less than max rating...I wouldn't be too concerned.

To agree with the others....compression fittings are for soft copper and plastic TUBING only....not pvc or cpvc PIPE.

For a repair...Sharkbites are super simple and reliable. You wouldn't want to pay the cost for re-piping an entire house though.

pvc

I never knew you could not use a compression fitting on pvc or cpvc.
Thank you for telling me.

I have a fitting made of ?white plastic that is a compression fitting. It has the compression nut on each end where you slide the pipes into to join them. I thought because it was plastic it was for pvc.

I have used Shark before and it is great but expensive.

Like this, Peterr?

That is known as a Dresser coupling and the ones made of plastic ARE for plastic piping. I have been under the impression that you have been asking about a brass fitting.
