About Plastic

About Duct Connections

About Duct Hose

For Use With: Beverage, Drinking Water, Food, Water
Maximum Temperature: 140° F
Specifications Met: ASTM D3350, NSF/ANSI 61
Fittings: Use Nylon Plastic, Polypropylene Plastic, PVC Plastic

While not as flexible as soft tubing, this pipe can still bend around objects, resulting in fewer connection points in your line. Fewer connection points not only shortens installation time, but also allows for smoother flow through the line. Pipe connects to barbed pipe fittings with a clamp (sold separately). It is made of high-density polyethylene (HDPE) for excellent strength and corrosion resistance. It meets NSF/ANSI Standard 61 for drinking water and ASTM D3350 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.

Underground Snap-Lock Polyethylene Pipe Fittings for Drain, Waste, and Vent

For Use With: Water
Specifications Met: ASTM F667

The snap-together design allows you to quickly connect these fittings to pipe with no cement required. Fittings are typically used in gravity-flow drainage applications. Made of high-density polyethylene (HDPE), they stand up to freeze/thaw cycles and resist corrosion and stress cracking. Fittings meet ASTM F667 specifications and testing requirements for material quality as well as soil conservation service (SCS) standards for use in underground drain lines.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas. Do not expose fittings to direct sunlight.

Underground Snap-Lock Polyethylene Pipe for Drain, Waste, and Vent

For Use With: Water
Specifications Met: ASTM F667

Pipe has a snap-together design that allows you to quickly connect to fittings with no cement required. It is typically used in gravity-flow drainage applications. Made of high-density polyethylene (HDPE), it stands up to freeze/thaw cycles and resists corrosion and stress cracking. Pipe is corrugated inside and out for flexibility. It meets ASTM F667 specifications and testing requirements for material quality as well as soil conservation service (SCS) standards for use in underground drain lines.

Nonperforated pipe allows you to flow drainage to one area. Perforated pipe has slits along the entire length that allow drainage to be dispersed.

Female/male ends connect to female or male snap-lock fittings. Male ends allow you to join two lengths of pipe without the need for a fitting.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas. Do not expose pipe to direct sunlight.

Hose

Hose Cuff

Flexible
Compatible Clamps: Worm-Drive and Twin-Ring Clamps
Color: Gray
Temperature Range: -40° to 150° F

The smooth interior prevents dust from getting trapped and building up inside the hose. Hose is for use with lint, dust, and sawdust.

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

Slippery UHMW Polyethylene Tubes

These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.

Tubes with an oversized OD also have an undersized ID for finishing to the sizes listed.

Tight-tolerance tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall.
