About Conduit

Clear-View Standard-Wall Plastic Pipe for Water

See inside your line with this clear pipe, which works in a variety of residential and commercial low-pressure plumbing and water supply applications. It connects to standard-wall plastic pipe fittings. Made of PVC, it has good corrosion resistance. Join this pipe to unthreaded female socket-connect fittings using a PVC primer and cement (also known as solvent weld).

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

Clear Semi-Flexible Pipe

For Use With: Water
Maximum Temperature: 140° F
Fittings: Use Schedule 40 PVC Plastic
Flanges: Use Schedule 40 PVC Plastic

Semi-flexible pipe isn’t as bendable as soft tubing, but it can still bend around objects, resulting in fewer connection points in your line. Fewer connection points both reduces installation time and allows for smoother flow through your line.

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

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.
