Supply House out does local and online stores

I had trouble finding this fitting at local hardware stores and other online stores, including Amazon. Prices are competitive or better. Processing and shipping is fast and includes email notification. I know I have a good price and I know where my order is and when it will get here. Hard to think how this could be better.

Q: I am trying to reduce from 4" to 1". Since I don't see a 4" to 1" reducer I was going to use the 4/2 and 2/1 reducers together. Will the 2" ends butt together or will one slide inside the other?

Q: Will 3" x 2" copper sweat reducer work with 3" M or L Tubing. Please include the ID size of 3" side and the 2" side.

Asked by rocki 11 years ago

Copper tubing OD is the same for all types…..3in copper "L" and "M" are both 3.125 OD and 2" inch copper is always 2.125 in OD so any sweat fitting reducer that is 3 to 2 will work. The only diameter changes will be on the inside of the copper tube because of the different wall thickness between "M" "L" and "K" type tube. Sweat fittings for OD use will all be the same ID so they can fit any type tube. I would assume they would be the same ID as the OD of the tube. 3.125 and 2.125 respectively or within a ten thousanth or so.

I've never ordered a 4x2 cxc however, I refer you to the "copper handbook" where it states that the female end of a 4 must be between 4.128 and 4.133 and of the 2 inch, 2.128 and 2.133. I've attached pg 36 for your reference. Joe Greene

Not with a solder iron....a bottle torch will work. paul

No, it cannot be attached with a soldering iron. A soldering iron will not generate anywhere near enough heat. It requires, at a minimum, a propane or MAPP-gas torch. If you had any quantity of these to do, it would be better to have an acetylene torch like plumber's use. After getting the surfaces totally clean (using emery cloth, fine sandpaper, etc.), apply a very light coating of soldering paste. I have never had much luck with water-based soldering pastes and so I prefer the rosin-based stuff. Assemble the joint and heat it thoroughly, all around the outside. Occasionally touch solder to it so you can determine when it gets hot enough to melt solder. Once it's hot enough and the solder will melt and flow like water, apply solder all around the joint and then move the solder away.. Apply additional heat and you will see the solder "sweat" up into the fitting, filling the joint. At this point, remove the heat and leave it alone. The solder will solidify within a minute and then you can use a wet rag to cool the fitting and joint down. The fitting will still be 700 degrees or so, so be careful to avoid getting steam burns from the wet rag. It takes a little practice to get good at it, but it's not hard to learn. The keys are really: (1) everything must be totally clean and shiny, (2) the soldering paste must be rosin-based (3) use sufficient heat. Ken Morley

No, you need more heat than a soldering iron will produce.

NO , must use torch.

Was this review helpful to you?

No, not with a soldering IRON. The technique is the one used by plumbers: clean the coupling and the piping surfaces to be joined (with fine grit sandpaper, for example), assemble the join, and use a propane torch and a non-lead, acid solder (coil or thin bar) at each end of the coupling to form a complete seal there. Books or internet sites on plumbing give step by step instructions. Good luck.

Q: Use: shower drain connection will this fitting work with an existing copper shower drain pipe (o.d. 2.125"). I need to connect the copper drain pipe to the plastic shower drain pipe (o.d=3.0, i.d=2.38). Would like to slip plastic drain (I.D. OF 2.38") over the 2" copper drain (copper o.d. 2.125").

This would not be the fitting to use. It connects to copper via soldering on each side.

That won't work, though a good idea in theory. The proper transition fitting would be a Fernco 3001-22 which is meant to join 2" copper to 2" PVC. Adam J. Goldberg Sent from my iPhone

NO. USE 2" FEMALE COPPER THREADED ADAPTOR THEN 2'' PVC MALE THREADED ADAPTOR IF SPACE ALLOWS, IF NOT USE A RUBBER COUPLING.

Q: Will this fit over 1/4 inch OD tubing on one end and 1/2 inch OD tubing on the other? I'm trying to join 1/4" copper piping to 1/2 inch piping...

The WP0-08-04 adapter will fit over copper pipe with an OD of 5/8" on one side and 3/8" on the other side. Unless they are designated as HVAC fittings, all the copper sweat fittings we sell are sized by the nominal size of the pipe with which they are compatible. The nominal size will always be 1/8" smaller than the outside diameter.

Q: Will this fit over a "3 inch" pipe that has a 3 and 1/8 inch outside diameter? Or, what is the inside diameter of the 3" end?

The 3" end of this fitting is designed to fit over copper pipe with a 3-1/8" outside diameter. The fitting itself has an inside diameter slightly larger than 3/1/8" (between 3.128" and 3.133" to be more precise).

a coupling would be 3-1/8” x 1-1/8” shown below. Pipe measurements refer to the inside diameter of the pipe. Copper pipe is typically 1/8” thick.

It's hard to say. If the fitting shown is a reducing coupling or a reducing bushing. A coupling is made to go over the pipe and therefore the opening or ID would be 3 1/8. A bushing is made to go into another fitting, such as a Tee or a valve so then the OD of the bushing would be 3 1/8. Hope this helps.
