EMT & Flexible Conduit

Conduit is an excellent way to protect cables over long runs. The main types include flexible non-metallic (similar to solid Wire Loom), flexible metallic, and EMT conduit. Typically the flexible types are made of a corrugated material that encloses cables and wires to protect them from water, vibration, oil and other corrosives over long distances. It's typically made of materials like PVC, aluminum, or steel. This type of conduit is great for areas that need cables to be able to bend along their route. Metallic conduit is useful for high heat environments, or areas that require extra strength.

EMT (Electrical Metallic Tubing) conduit is a non-flexible, non-corrugated raceway designed specifically for electrical cables. Our EMT conduit is made of galvanized steel to prevent chipping, cracking and peeling.

Additionally, we have all the fittings and connectors needed for all types of conduit, including fittings to couple EMT tubing to flexible conduit.

Don't Just Do It ... Conduit


Let's talk about conduit. A conduit is a channel through which something is conveyed. Conduits take many shapes and forms, but in the electrical field, conduit has a more specific and narrow definition: it's a tube, pipe or trough that protects and routes electrical wiring. That said, not all electrical conduit is created equal: there are different types that have different applications in the field. Let's take a look at some of the conduit offerings out there.

But first, what makes conduit preferable to other wiring options? Since it's fully enclosed, it offers excellent protection from outside damage from things like moisture, abrasion, chemicals and other perils…it can even keep out fire when properly sealed. It can be modified to be waterproof, or able to be submerged, and certain types can be encased within concrete. Metallic conduit helps shield cabling from electromagnetic interference, and makes it fairly easy to add or remove cables as needed.

However, it can be more costly than other open wiring methods, so if the added protection isn't needed, it may be more advisable to take a more economical approach such as cable trays or support rings. Additionally, heat dissipation can be an issue with fully enclosed conduit, meaning that if you have multiple cables in a single pipe, you may need to lower the current capacity of your conductors.

Non-Flexible Metal Conduit

Examples of rigid EMT conduit

There are a number of types of non-flex metallic conduit, often made of steel, stainless steel or aluminum. RMC (rigid metal conduit) is thick-walled, with threaded ends for fitting and coupling. GRC (galvanized rigid conduit) is galvanized steel with a wall thick enough to accommodate threading, though it may not always be threaded. EMT (electrical metal tubing) is thin-walled, which makes it less expensive and lighter than other metallic rigid conduit types. IMT (intermediate metal conduit), as its name implies, is lighter than RMC, but heavier than EMT.

EMT is the type of metallic non-flex conduit we offer at CableOrganizer.com. Since it's thin-walled, it cannot be threaded, which means fittings must be clamped in place. Though it's the thinnest-walled of the rigid conduits, it still provides ample protection in most applications except where serious damage is anticipated, and its light weight makes it easy to handle and alter as needed. It's often used in commercial or industrial applications.

Electrical Metallic Tubing

Flexible Metallic Conduit

Jacketed and non-jacketed flexible metallic conduit

Flexible conduit is ribbed, giving it a look similar to corrugated wire loom, and is able to bend and flex freely (though it does not hold a bend permanently as a bent pipe would). For areas where obstacles would require rigid conduit to make too many turns and use an impractical number of fittings, flexible conduit may be an ideal choice. Flexible metallic conduit (FMC) provides the protection of rigid metal conduit without being confined to traveling in straight lined sections. It also provides vibration isolation when connecting to motors or other devices prone to movements, where rigid conduit would be easily jarred.

It should be noted that FMC, due to the interlocking coils that allow it to bend, is not liquid tight unless it features a waterproof plastic coating. This type of conduit is known as LFMC (liquidtight flexible metallic conduit).

FMC should not be confused with FMT (flexible metallic tubing). It is used in lighting fixtures and other plenum applications, and is liquid-tight despite not having a jacket. Visually, it features tighter, thinner “ribs” than FMC.

Non-Metallic Flexible Conduit

Examples of PVC flexible conduit

There are many varieties of non-metallic flexible conduit, but most share basic properties. They are often constructed of PVC and feature a corrugated exterior. Varieties exist to handle communication cables, fiber optics, and other low-voltage cabling. Depending on the type, it may be UV resistant for outdoor use, or suitable for burying. Since it's typically made from a solid piece of material, it's watertight, but resistance to chemicals and corrosives will vary. PVC flexible conduit is found in riser applications, HVAC areas, water treatment systems and many other applications.
