UV-Resistant Standard-Wall PVC Pipe Fittings for Water
- For Use With: Drinking Water, Water
- Maximum Temperature: 140° F
- Specifications Met: ASTM D1784, NSF/ANSI 61
- Pipe Nipples and Pipe: Use Schedule 40 PVC Plastic
Use these fittings in outdoor environments—the material has an additive that protects against the damaging effects of ultraviolet light. Fittings meet NSF/ANSI Standard 61 for drinking water. Also known as Schedule 40 fittings, they are typically used in residential and commercial low-pressure plumbing and water supply applications. They are PVC, which has good corrosion resistance. Fittings meet ASTM D1784 specifications and testing requirements for material quality.
Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
Crush-Resistant Flexible Duct Hose with Wear Strip for Dust
- Flexible
- Compatible Clamps: Worm-Drive and Quick-Release Clamps
- Color: Black or White
- Temperature Range: -60° to 275° F
Surrounded by a protective plastic spiral, this hose bounces back to its original shape when stepped on and resists wear from being dragged across rough floors. Hose has a smooth interior for unrestricted flow. It is often used with lint, dust, and sawdust. It meets UL 94 HB for flame retardance.
Hose that is FDA compliant can be used with dry food, such as flour and sugar.
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
- Specifications Met: UL 94 5VA, UL 94 5VB, UL 94 V-0
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.
