Q: I’ve selected a spin-through rod guide or coupling intended for use in the tubing size I’ve selected, but PC-PUMP gives me an error saying that the rod guide does not fit in the tubing. Is there an error in the database?

A: Some spin-through rod guides or couplings in the database have an outside diameter which is intended to fit relatively tightly within the tubing. These are designed to work in the most common tubing weights for the particular tubing size. If you have selected one of these guides and are using a heavier weight of tubing, the inside diameter of the tubing may be too small for the guides to be run. Use a different guide or select a lighter weight of tubing. If this happens when you are using the lightest weight of tubing for the given tubing size, please email your .pcp file to C-FER with a message describing the problem.
