M&P manufactures Plastic Pipe End Caps designed to fit over standard line pipe outer diameters (O.D.).
Our heavy-duty plastic pipe caps protect line pipe ends during shipping, storage, and handling, preventing costly damage to pipe bevels while keeping the inside diameter clean and free from contamination.
Plastic pipe cap end protectors are engineered for tough industrial environments, providing long service life with natural UV resistance for outdoor exposure.
Key Benefits
-
Protects pipe bevel ends from impact and deformation
-
Keeps dirt, debris, moisture, and animals out of the pipe
-
Long-lasting, reusable, and weather resistant
-
Made in the USA
We can manufacture the exact size plastic pipe cap you need.

National Pipe Thread Taper (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. In contrast to straight threads that are found on a bolt, a taper thread will pull tight and therefore make a fluid-tight seal.
