Looking to buy some top quality flexible conduit ends? Here are some advices and extra details helping you to make the best choice.
The ID and OD means inner diameter and outer diamter of flexible conduit. OD is the maximum of flexible conduit, and is a fixed number that can not be deviated from. Flexible conduit are always corrugated inner and outer, so we’d better leave more space inner to make wires and cables easier to through. So we should leave 20% space based on inner diameter. It may sound backward but use the diameter of the conduit as a guide to the service needed. It is better to use a conduit that is too big than one that is too small.
Rigid metal conduit is a heavier gauge steel electrical conduit using threaded couplings and fittings and is the thickest, or stiffest of the conduit materials used for electrical wiring. A typical RMC and often the only RMC residential application is to enclose the electrical service entry wiring from the electrical company’s overhead wires at the mast-head down to the electrical panel mounted on the building wall.

RMC and IMC can be used interchangeably, with IMC more common these days because it’s lighter and somewhat easier to work with than RMC. They are permitted for use by the NEC in dry, wet and corrosive locations and can be buried in many applications. They typically are joined with threaded connectors and fittings.
The flexible metallic tubing (FMT) is made to give great flexibility and includes a metallic tube-like design. It really is very easy to route or shape to fit probably the most difficult areas. That is why it is great to utilize on the do-it-yourself projects where it is much better to not join multiple components of Stainless Steel Flexible Conduit together. Also, this kind of tubing does not feature any form of waterproof protection.
Electrical nonmetallic tubing (ENT) is flexible corrugated plastic tubing that is moisture-resistant and flame-retardant. It is easy to bend and installs with snap-lock or glued plastic fittings. Unlike EMT, non-metallic tubing cannot installed in exposed locations, so it is commonly used inside walls. In addition to installation in standard wood- or metal-frame walls, ENT can be installed inside concrete block structures and can be covered with concrete. Due to the blue color of one common brand of this conduit, ENT is nicknamed “smurf tube,” after the Smurfs cartoon characters.
