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 it mean to have ANSI Certification for lead free plumbing products?"
A. Laws requiring plumbing products that come in to contact with drinking water to be essentially lead-free (0.25% weighted average) have been passed in California and Vermont. In order for companies to ship these plumbing products to locations in CA and VT, they must be ANSI certified lead free.

Q. "What is CA AB 1953 and VT S.152?"
A. CA AB 1953 is a California Assembly Bill that defines "lead free" to mean not more than a weighted average of 0.25% lead content in pipe and fittings. VT S.152 is a Vermont Senate Bill that mimics the California AB 1953 and regulates the amount of lead to a weighted average of 0.25% or less.
