3" to 2 1/8" ID Copper Reducer Reducing Coupling Fitting Pipe Tube Adapter

About this item

To step a large copper line down in size, you need a reducer. This 3" to 2-1/8" ID copper reducing coupling is listed new and sold as one piece. The seller gives the sizes as inside diameter (ID), which is worth understanding before you cut pipe.

Will this 3" to 2-1/8" copper reducer fit my tube?

Copper tube is usually sold by nominal size, while fittings are made to slip over the tube's outside diameter. Since this listing gives ID measurements, measure your tube's OD and compare it with the seller's photos or description, or ask the seller.

• Type: reducing coupling.
• Joining: the title doesn't say. Check for solder cups or press ends.
• Uses: large supply lines, mechanical rooms and HVAC piping.
• Heat: if it's a sweat fitting, a joint this size needs a larger torch tip and even heating.
