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.

Semi-Flexible Plastic Pipe for Water


- 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 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.

Multipurpose Blended Neoprene Foam Tubes

- Color: Black
- Temperature Range: 0° to 165° F
- Cell Type: Closed
- For Use Outdoors: Yes
- Density: 22 lbs./cu. ft.
- Pressure to Compress 25%: 9 psi (Soft)
- Tensile Strength Rating: Not Rated
- Oil-Resistance Rating: Good
Neoprene is blended with EPDM and polyethylene for foam tubes that offer good resistance to water, sunlight, and oxidation. Use them as jackets, seals, and insulation. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed. Tubes have an ultra-smooth texture for a sleek surface that's easy to wipe down.
