How to identify pipe based on size (Outer Diameter, Inner Diameter, Wall Thickness) and Pipe Classification

The chart you see below is sorted based on the OD (Outside Diameter) of the pipe. Once you know the OD, you will see a grouping of pipe with the same OD. Any pipe with the same OD will take the same fittings as any other pipe in that grouping. However, you have to pay attention to the certification or classification of the pipe. If you are just assembling pieces and it'll never be used for plumbing purposes then any fitting will work and interchange. However if this is something for plumbing or sewers, you must match the class of the pipe with the class of the fitting (or a rating above.) If you prefer our original Flexible & Rigid PVC Pipe Size Table with Dimensions & Pressure Ratings Chart it's still available. We also have the page for telescoping possibilites.

If you don't know the difference between pipe, hose and tubing, please see our Pipe & Tubing Identification Infographic. It's the easiest way to understand the differences between the pipe, tubing and hose products we sell. If you are not familiar with pipe sizing and standards please read Understanding and Identifying Your Pipe Size; For the normal person, not engineers.;-)

The chart or table below gives you two methods of identifying your pipe.

Method #1 is represented by the light blue panels. You need to know nominal pipe size and classification. (Usually printed on the pipe.)

Method #2 is represented by the light green panels. You will need the two data points in the light green panels to identify your pipe. If using method #2, the only sure fire way to do this is buy a digital caliper. We sell them but you can also buy them for about $15-$25 at many hardware stores and local auto parts stores. They are sometimes in the bargain bins. All you need to do is turn it on, be sure it's closed, hit the "zero" button and then open them to measure the OD and wall thickness of the pipe you are going to use. Find OD listed in the 1st column and thickness in the 3rd and then you'll find the classification for your pipe in the blue panel that corresponds to the OD and Wall Thickness you measure. Once you know the classification and pipe size, you are set. Just click on the "YES" in the last column to order.

NSF Rated means potable water, safe for human comsumption. Aka NSF-60, NSF-61, NSF-PW.

UV Rated means rated for use outdoors in the sun and also with high intensity UV light sources (Grow houses, algae farms, etc.)

Furniture Grade means safe for use outdoors in the sun. Will not discolor or become brittle. Has no writing on it and has a nice smooth shiny exterior finish.

Most pipe is PVC, some is CPVC. Most CPVC is also NSF rated and can take up to 180F continous temperatures. (Standard PVC is rated to 140F.)

≅ means "approximately equal to"

*Min. Wall thickness, weight, and inner diameter are all approximate and can vary +/- 7% unless otherwise noted. Miniumum wall thickness is just that, the smallest wall thickness. It is typically larger. Therefore the ID is typically smaller. The Outside Diameter is held to a much tighter tolerance: usually within 0 .25% or just a couple thousandths on small pipe. Also note: All pipe can be oval or oblong, not a lot, but it is common to see a small egg shape, especially on the ID. On large (12"+), thinwall pipe it can be up to 1/2" difference between the min. and max. axises.

**Stock refers to pipe sold "by the foot" and less than full length quantities. If we sell it "by the foot" there is an excellent chance we can sell it in 10' or 15' or 20' sticks. However such purchases have to be shipped via LTL truck (10' and 15') or Flatbed Truck (20') which gets expensive unless you are buying large quantities of pipe. Please contact us via email for questions and pricing of 10', 15' and 20' sticks of pipe.

***Disclaimer: Pressure ratings above are for a temperature of 68-73F. See de-rating chart below for higher temperatures.

Note: The temperature ratings above are for the temp of the pipe, not the fluid traveling through it. Typically the temperature of the pipe is much less than the fluid going through it due to radiation (heat loss) and the heat barrier effect, ie the insulating properties of the pipe.
