0.57" Tubing | McMaster-Carr

Often used in place of aluminum for structural frames, machinery components, and robotics, these tubes are lighter in weight and almost as rigid. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Thanks to these tubes being lightweight, they reduce wear and stress on motorized parts to extend the life of machinery.

Checked carbon fiber has the classic carbon-fiber look and is easy to machine—it won’t fray or splinter when cut. Glossy carbon fiber has a shiny finish that can be sanded to matte.

Liquid-Tight Flexible Plastic Conduit

Conduit

The spiral design makes this conduit flexible. When used with liquid-tight fittings, it seals out liquid and resists oil, corrosion, and UV light. Route it around tight bends and use in high-vibration applications or those that require periodic flexing. This conduit cuts cleanly with no jagged edges and has a smooth interior that protects wire and cable from abrasion when being pulled.

Straight Adapters

Push-In × Threaded

Use these adapters to attach liquid-tight flexible plastic conduit to a knockout in an outlet box or enclosure. They provide a connection that seals out liquid and resists oil, corrosion, and UV light. They are UL listed when used with abrasion-resistant liquid-tight flexible plastic conduit (Type B).

Adapters with a push-in end are removable and reusable.
