In the offset example, the insertion depth for each 45-degree fitting is what?

• A. 1/2 Inch
• B. 1 Inch
• C. 3/4 Inch
• D. 1 1/4 Inch

Answer: (C)

In an offset made with 45-degree fittings, you have to account for how far the pipe actually slides into each fitting—the insertion depth. That depth is part of the pipe that isn’t contributing to the straight run between bends, so it must be subtracted from the overall length you’re trying to achieve. For this offset problem, the standard insertion depth into each 45-degree fitting is 3/4 inch. That means each bend consumes 3/4 inch of pipe length. Therefore, the correct insertion depth to use for calculating the offset is 3/4 inch. Using a smaller depth would under-seat the pipe, and a larger depth would over-correct the run, throwing off the alignment. The other depths don’t match how far the pipe actually sits inside the fitting for this setup.
