Common Terms
(and what they mean)

S or Slip: A regular hub. The pipe glues into this (same O.D. as coupling)

Mips: Male pipe threads on the outside of fitting

Fips: Female pipe threads on the inside of fitting

Spigot or SP: The same size as the pipe. Will glue into another fitting

Hyset: Has a nailing flange on the front of the fitting

Dropear: Has a nailing flange on the back of the fitting

Nominal: Used to describe copper pipe and fittings in plumbing. Refers to the inside diameter of the pipe which varies by thickness of the pipe. The outside is a constant size and is always 1/8" larger than the nominal size. Example: 1/2" nominal is always 5/8" O.D.

Frequently asked questions about copper fittings

"I have 1/2" copper fittings, can I use 1/2" o.d. copper tubing with those fittings?"
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.

We offer many thoughts (quotes) to ponder, such as:
"A lot of people are afraid of heights. Not me, I'm afraid of widths." - Steven Wright
