Searching to purchase the best pvc flexible conduit? Here are some advices and extra details helping you to make the best pick. Liquid-tight flexible metal conduit (LFMC) is a special type of flexible metal conduit that has a plastic coating and is used with sealed fittings to make it watertight. It is commonly used with outdoor equipment, such as air conditioner units.
Each type of conduit has its own fittings (which connect lengths of conduit together) and connectors (which join conduit to boxes). Fittings include straight couplings and various elbows and tees, much like plumbing fittings, for extending or changing the direction of the conduit run. Some fittings have removable plates or covers that provide access to the conduit interior to facilitate pulling the wires; when installed, these are often referred to as “pull points.”
Intermediate Metallic Conduit or IMC is lighter weight, metallic conduit and is rated as stronger than other rigid conduit. IMC was first produced by Allied Tube & Conduit. IMC, provided in both threaded IMC and non-threaded IMC forms, is a rigid metallic conduit tubing, typically hot-dipped galvanized steel or stainless steel. The interior of galvanized steel IMC is usually coated with an anti-corrosion layer. Threaded IMC is joined by threaded couplings, C condulets, sweeps and bends. The tubing is cut with a pipe cutter or tubing cutter, and then threads cut using a thread cutting tool. When cutting IMC, take care to remove burrs on the tubing interior that would otherwise damage electrical wires being pulled through the conduit.

The liquid tight flexible non-metallic conduit (LNFC) is really a reliable option for a wide range of applications. It is built to be really hard-wearing and protective having the ability to give defense against water and flames. Plus, certain LNFC may be manufactured with multiple layers to provide extra strength. This is basically the most practical form of Plastic Flexible Conduit Fittings to make use of in locations which might be seen as potentially hazardous.
There are strict regulations in dealing with the fill factor. A cross-sectional area of the conductors inserted would be measured and the code would determine the percent of conduit which could be filled. A conduit can never be filled 100 percent as it is not safe. The code has determined how wires and bundles of wires can safely run through a given flexible conduit. The table does not address any difference in high or low voltage cables so you can apply the table for both uses. Have this information readily available when shopping for conduits.
