Plastic Metric Pipe | McMaster-Carr

This polypropylene pipe resists the damaging effects of ultraviolet light, so it’s suitable for outdoor use. It has the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Pipe has thick, strong walls for heavy duty chemical processing applications. It meets ASTM D4101 specifications and testing requirements for material quality.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings for a variety of residential and commercial low-pressure plumbing and water supply applications. It’s made of PVC, which has good corrosion resistance. Connect to unthreaded female socket-connect fittings using a PVC primer and cement (also known as solvent weld).

Pipe for drinking water meets NSF/ANSI Standard 61.

Pipe that meets ASTM D1784 and ASTM D1785 adheres to specifications and testing requirements for material quality.

Bend radius is the point to which you can bend pipe or tubing without damaging it. The smaller the measurement, the better the bend.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Clear Impact-Resistant Polycarbonate Tubes

Color: Clear
Temperature Range: -40° to 200° F
Tensile Strength: 8,900-9,500 psi (Good)
Impact Strength: 12-18 ft.-lbs./in. (Excellent)
Hardness: Rockwell R118 (Hard)
