0.38" Hose | McMaster-Carr

Nylon tubing can handle higher pressures than polycarbonate tubing. It won’t crack even at low temperatures. Tubing is semi-flexible, so it is good for gradual bends. Semi-clear tubing gives you a limited view inside the line. Opaque tubing doesn’t allow you to see what’s flowing through the line.

Electrical-Insulating Tube Sleeving

Add a layer of insulation to prevent electricity and heat from dissipating from wire and cable. This sleeving is often used in motors, transformers, and generators. Made of coated fiberglass, it resists abrasion, acids, alkalies, and chemicals.

Acrylic-coated sleeving is more flexible than vinyl-coated sleeving, so it bends around tight corners. It resists solvents and oil.

Chemical-Resistant Tube Sleeving

Made of PVC, this sleeving resists chemicals, oil, and acids. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Because this sleeving is non-expandable, it does not stretch, so it’s best for applications where you know the exact diameter of the items you need to protect.

Flexible Metal Conduit

Conduit

Also known as FMC, this conduit offers the crush resistance of metal combined with flexibility to handle bends in tight spaces.

Zinc-plated steel conduit has a heavy zinc coating for corrosion resistance. Aluminum conduit is lighter than steel and has good corrosion resistance. It's often used to hook up motors and light fixtures.
