Frequently Asked Questions

Q. "I have 1/2" copper fittings, can I use 1/2" o.d. copper tubing with those fittings?"
A. Probably not. In the plumbing trade when we say 1/2" fittings we mean fittings that use 1/2" nominal pipe. To figure what size pipe to use with standard plumbing fittings, you must add 1/8" to your measurements to know the o.d. (outside diameter) of the pipe. 1/2" nominal fittings use 5/8" od pipe; 3/4" fittings uses 7/8" pipe and so on.

Q. "I have 'refrigeration grade' copper tubing. How do I determine which size copper sweat fittings to use?"
A. Refrigeration grade copper tubing is sized according to the outside diameter of the copper pipe. The plumbing industry uses the inside diameter (nominal) size of the pipe for their measurement of sweat fittings. To figure what size sweat fittings to use on refrigeration grade tubing you must subtract 1/8" from the outside diameter of the pipe measurements. If you have 1/4" outside diameter refrigeration grade tubing then you will need to order 1/8" (nominal) sweat fittings. Click here, to see our conversion table.

Q. "What does nominal mean?"
A. Manufacturers of copper pipe and sweat fittings use the inside diameter (nominal) size of the pipes for their definition of their pipe and fitting measurements. Some companies use the abbreviation CTS for copper tube size to refer to the copper nominal size. The term nominal is used because the inside diameter is not a precise measurement due to the different pipe thickness used for copper pipe. The outside diameter stays constant so the inside diameter will vary slightly. Since the outside diameter stays constant you can measure the outside diameter of a copper pipe and then you will be able to convert that measurement to the nominal pipe size. This will help you to determine the correct size of sweat fittings you will need. You can do this by taking the outside diameter measurement of the copper pipe and subtract 1/8" from that measurement which will give you the nominal inside diameter. View our conversion table.

Q. "Why are some of these fittings, valves, and nipples not for potable water?"
A. Starting January 1st of 2010, California and Vermont enacted new lower lead laws and many more states are adopting such laws. Before that time, these top quality brass products were legal for potable water and products used throughout the world and actually contain much less lead than products manufactured before the 1980's.

Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be essentially lead free (less than 0.25% weighted average). For further information about how the law determines what is lead free, rules regarding which plumbing products must be lead free, and who these laws will affect, please visit our LEAD FREE Plumbing Information page.
