Plastic conduit is a tubing that is made from a plastic material that is used to protect wires or hoses from damage. Popular materials for non-corrugated and corrugated tubing are PVC (polyvinyl chloride), PA (polyamide), and PP (polypropylene).

Types of Plastic Conduits

Flexible plastic conduits generally fall into three varieties differentiated by their manufacture: corrugated, spiral, and smooth walled.

Corrugated plastic conduits are most commonly made from the following modified plastics: polyamide 6 (PA6) nylon, polyamide 12 (PA12) a high-performance nylon, polyurethane (PU), and polypropylene (PP).

Corrugated plastic conduits are available in liquidtight non-split and non-liquidtight split versions

Corrugated nylon conduits of PA6 and PA12 have the best overall features of all the conduits.

  • Highly flexible
  • Suitable for reverse and multi-directional bending
  • Non-collapsing walls on tight bends, no-kinking
  • Very broad temperature ranges
  • New multilayer versions offer the highest flexibility and additional wall strength
  • Abrasion resistance
  • Best smoke, toxicity, and flammability ratings
  • Excellent tolerance and stability to chemicals in the installation environment
  • Ease and speed of installation
  • Most industry certifications and approvals

Application:

Pros: machine building, robotics and high motion equipment, railway passenger car inside and outside wiring, security and HDTV cameras, signage wiring, automated systems, packaging machines, autonomous vehicles, electric-vehicles, renewable solar & wind power generation, medical fiber optic bundle protection 

Cons: not the best choice for food and pharma applications due to the corrugations and the stringent cleaning required in this industry

Corrugated PU conduits have a broad application temperature range and chemical tolerance. They are the most flexible corrugated conduits however, become flimsy on longer installation runs and may need additional mounting support.

Corrugated PP conduits typically have a broad temperature range combined with very good chemical stability and tolerance. Split versions are often used in simpler applications needing non-liquidtight, easy to use, quick install, flexible wire bundling, like under the hood around automotive engines, trailers and the like.

Spiral plastic conduits are commonly made from soft PVC, or polyurethane (PU) sheathing. The unique feature to spiral conduits is the support spiral wire or “spine” spiralling along and molded into the conduit wall. Hence the name. The spiral support wire is often made of a hard PVC or spring steel wire, and it gives the conduit wall support, keeping it round and open from collapsing.

Spiral conduits of PVC & PU have the following features:

  • Extremely flexible
  • Widely resistant to chemicals
  • Free of silicone and cadmium
  • Relatively easy to clean, and keep clean
  • Suitable as a suction or vacuum hose
  • A good choice for use with guide chains

The PU versions have additional desirable properties like high abrasion resistance, microbe resistant, flame resistant, free of halogen, and good low temperature performance.

Applications:

Pros: machine building, medical equipment, food and pharma equipment, plant wiring and construction, shipbuilding, automation equipment, and installation within cable guide chains.

Cons: limited choice of fittings, may need additional mounting support on longer conduit installations.

Smooth walled plastic conduits are made from a soft PVC with an embedded spiral, or just straight PVC wall.

Applications:

Pros: Good for general installations with little to no vibration or movement and short installation runs. Comparably low in cost.

Cons: Limited choice of available fittings, poor flexibility, difficult to pull wires through without the use of a wire lubricant. Cold temperatures can cause cracking.

Quick Facts About Plastic Conduits

Which brand of plastic conduits do you carry?

We supply only the Flexa brand of conduits. The Flexa family of flexible plastic conduits include the names:

  • ROHRflex corrugated polyamide nylon conduits
  • ROHRflex MULTI, corrugated nylon large diameter conduits
  • AIRflex spiral PVC & PU conduits
  • ROHRflex DUO-PA6 and DUO-PP two piece split corrugated conduits

FLEXAzip, single split conduit kit for repair and retrofit applications

When do I choose plastic conduit or metal conduit?

Plastic conduits are better suited for “light duty” applications. Applications where the chance is low, and the operating conditions are mild. Mild temperatures and no physical contact are idle situations to use plastic conduits

Metal conduits are best used in “heavy duty” applications. Applications where the chance of physical contact is high, and the operating temperatures are high as well. Applications in high heat or near open flames along with the chance of high impact make the metal conduits the idle choice.

How many wires or hoses can I put into a plastic conduit?

When it comes to how many wires to put into the conduits you first need to determine whether the plastic conduit needs to be flexible or not. If you need flexibility than typically 50% full is the idle amount to ensure you can maintain flexibility. If the application doesn’t need flexibility than you can fill as much as 100%.

Can you use the Flexa plastic conduits outside?

Yes. All Flexa plastic conduits are rated for outside usage. They all have a temperature range that ensures continuous outside usage as wells as full UV protection making it ideal for outside use. They completely sealed to ensure no water leaks into the conduit.
