EMT fittings are zinc plated and made from SAE 1006 steel and contain nylon insulating bushings. EMT fittings are similar to conventional EMT fittings both using either set-screw or compression rings to secure EMT pipes. Connectors are mounted to a metallic box using a steel locknut that screw on standard NPSM threads.
What metal is EMT conduit made of?
Electrical Metallic Tubing—EMT Another example of a rigid electrical conduit is EMT (electrical metal tubing), which is most commonly made of galvanized steel but can also be aluminum. The tubing itself is not threaded like RMC and IMC.
Is EMT conduit stainless steel?
Use Calbrite™ EMT conduit is made with stainless steel to meet stringent sanitary requirements. Requires no threading and is joined together using EMT compression fittings. Lighter weight provides cost savings on installation and shipping (weighs 57% less than stainless steel rigid conduit and 43% loss than IMC conduit). Bright finish.
Is EMT conduit galvanized?
Steel EMT is usually coated or galvanized to protect the conduit from corrosion. Steel EMT can also be harder to bend. Aluminum EMT is lighter and easier to bend for installation. In most instances, aluminum EMT conduit is more expensive than steel EMT conduit. Some manufacturers coat their aluminum EMT conduit to protect against corrosion.
Can you use EMT outdoors?
Wet locations - EMT can be used as long as all fittings are corrosion-resistant. Hereof, does outdoor wiring need to be in conduit? Generally, local codes require that outdoor wiring be protected by conduit in an instance in which outdoor wiring is installed above ground. If wiring will be buried, most codes allow Type UF cable.
What are the two main types of EMT fittings?
There are two main types of conduit fittings: connectors and couplers. Couplers (or couplings) are used simply to connect two pieces of conduit together. Couplers are available in different styles and sizes and allow you to form longer runs of conduit.
What are the 4 types of EMT connectors?
Bridgeport offers set screw, compression, push and raintight connectors and couplings for your EMT conduit installations.
What does EMT mean in pipe?

What's the difference between rigid and EMT?
Rigid metal conduit (RMC) is a thick-walled threaded tubing, usually made of coated steel, stainless steel or aluminum. Galvanized rigid conduit (GRC) is galvanized steel tubing, with a tubing wall that is thick enough to allow it to be threaded. EMT is generally made of coated steel, though it may be aluminum.
Can EMT be threaded?
EMT shall not be threaded. Exception: EMT with factory threaded integral couplings complying with 358.100. EMT shall be installed as a complete system in accordance with 300.18 and shall be securely fastened in place and supported in accordance with 358.30(A) and (B).
Can I use EMT outside?
Electrical metallic tubing (EMT): Lightweight and easy to install. Intermediate metallic conduit (IMC): Has a thicker, galvanized wall, making it suitable for outdoor applications.
Are EMT compression fittings watertight?
Crouse-Hinds series raintight EMT connectors and couplings are used in raintight environments to join EMT conduit to a box or enclosure, or to couple two ends of EMT conduit. The design prevents water seepage into the conduit, box or enclosure.
Are EMT compression connectors watertight?
A: Yes, as it is rated "Rain Tight".
Can EMT fittings be used on rigid conduit?
EMT connectors are permitted to be assembled into threaded entries of boxes, conduit bodies or internally threaded fittings having tapered threads (NPT).
What are MC connectors?
MC connectors are specially designed for low contact resistance and good stable connections under a wide range of conditions. MC means "multi-contact." The term "multi-contact" comes from the fact that the connectors have a bunch of little spring loaded gold plated fingers that ensure good contact.
What is the difference between a connector and a coupling?
Connectors look very similar to couplings but have a distinct difference. Connectors are meant to slide over the end of a piece of conduit on one side, and tighten down to the inside of a box or enclosure on the other end. You use connectors at the ends of conduit runs to land into a box.
How many connectors are in a box of EMT?
Electrical Metallic Tube (EMT) Set-Screw Compression Connectors with Insulated Throat (25-Pack)
What type of fittings should be used for EMT in a wet location?
Fittings marked “Raintight” are suitable for use in “Wet Locations.” ”Wet Locations” fittings are sometimes referred to as “Raintight.”
