How do I order the correct size I need?
This should seem simple, but it seems to be a little confusing. We want you to get the correct one the first time, nobody likes to receive their Raincaps and find out they don’t fit.
We will need to know the Outside Diameter of the pipe, or tubing, that you have. Yes pipe and exhaust tubing are measured differently. For example, a 2” exhaust tubing measures 2” across the OD. Simple. However, a 2” Sch 40 pipe measure 2 3/8” on the OD. Both are 2” products, but they each require a different size Raincap.
So really, all we need to know is the OD of the pipe or the tubing, but we also have a chart available that will help you get the correct Raincap if you are working with pipe systems.
