4 Inch diameter Clear 40 PVC pipe (Schedule 40), Cut to Length.</br>PVC pipe is measured by the nominal inside-diameter (ID), not the outside-diameter (OD).</br>Pipe has an approximate ID of 4.0 inch and an approximate OD of 4.5 inch, per PVC Schedule 40 Specifications. As with all extruded pipe, the inside diameter can vary a little. Tolerance for the inside diameter is +/- 2% of the stated diameter.</br>This pipe is manufactured in strict compliance to ASTM D1785.</br>Pipe has a bluish tint to prevent yellowing from UV light (as seen in pictures).</br>For use with standard PVC fittings and PVC cement.</br>If using with an end cap, be sure to use a Schedule 40 or Schedule 80 cap and not a sewer and drain cap (DWV). A DWV cap will not fit as it is made to be used with thin-walled drainage pipe.</br>This pipe should be protected from the sun. Extended exposure to ultraviolet light may cause discoloration and the heat may cause warping.</br>Length Tolerance: +/- 1/16 Inch</br>Please note that there is no product packaging with this product, it is just the pipe itself.</br>How to cut: If you need to cut the pipe, you should avoid using a ratchet-style PVC cutter, as that will likely break this pipe. Instead, use a saw such as a hacksaw, miter saw or radial arm saw, or one of the pipe cutters that you tighten a little, turn on the pipe, tighten some more and turn on the pipe and repeat until the pipe is cut.
