About Plastic

Flexible
Compatible Clamps: Worm-Drive and Quick-Release Clamps
Color: Clear or Black; Wear Strip is Yellow
Temperature Range: -40° to 200° F

Hose has a plastic spiral that acts as a wear strip to protect against damage. The interior is smooth for unrestricted flow.

Clear hose lets you monitor flow.

Warning: Hose should not be used for applications that generate a static charge.

Chemical-Resistant PVC Tubes

When working near chemicals such as acids and alkalies, these tubes offer 360° protection to wires, cords, and anything that can slide through them. They’re made of PVC Type 1, a material that’s easy to thermoform, plus it is an excellent insulator. These tubes are oversized on the outside and undersized on the inside to allow for finishing to the sizes listed.

High-Temperature CPVC Tubes

Color: Gray
Temperature Range: 32° to 200° F
Tensile Strength: 7,090-7,750 psi (Good)
Impact Strength: 1-2 ft.-lbs./in. (Poor)
Hardness: Rockwell R118-R119 (Hard)
For Use Outdoors: Yes

Just as resistant to acids and alkalies as PVC, yet CPVC withstands higher temperatures. Use these tubes to protect wires and cords from chemicals, or make them into parts for chemical-processing applications. They are easy to thermoform, plus they’re excellent electrical insulators. The OD is oversized and the ID is undersized to allow for finishing to the sizes listed.
