In electrical conduit installation systems, changing the angle is always considered a very important challenge; however, with the presence of the conduit pull elbow, the ability to change the angle of passing wires and cables with a very smooth angle has been provided. This elbow, which is available in two angles of 45 and 90 degrees, enables safe direction changes in electrical conduit installation without exerting excessive pressure on the wires and cables. With just a few high-quality conduit pull elbows, electrical conduit installation on uneven paths is provided in the best possible way.
A conduit pull elbow is one of the electrical conduit fittings used to change the direction of conduits at a 90-degree or 45-degree angle. This part is usually made of galvanized steel or stainless steel to be resistant to rust, corrosion, and mechanical pressure. In summary, the conduit pull elbow allows steel electrical conduits to be installed in an organized and safe manner in horizontal and vertical paths without the need for direct bending of the conduits. These elbows are used in industrial, construction, and facility cabling projects to maintain network organization and prevent damage to cables.
Most conduits and pipes designed and manufactured to support and protect electrical cables are made of steel or stainless steel. Of course, there are also various types of PVC electrical conduits, each used in lower-stress environments. However, steel electrical conduits, due to their structural material and high resistance, can be implemented in the network in heavy industrial projects.
But the main question here is: what materials are the fittings of these conduits, such as conduit pull elbows, mostly made of, and is their resistance and strength compatible with steel conduits or not? In response to this question, we must say that all fittings mounted on various types of steel conduits are entirely made of steel material and certain high-carbon iron derivatives. Fittings made from this type of material certainly have high compatibility and harmony with steel conduits, so you can easily use these parts together with conduits.
Given the controlled and relatively low thickness of steel electrical conduits, the technique used for bending these pipes is the cold bending method. Using special machinery and equipment, sections of the conduit are prepared to be transformed into conduit pull elbows. The conduit is then secured in the machine, and the bending stages are carried out through gradual and slow rotation.
An important point to mention about this method is that no structural deterioration occurs in the conduit during the bending stages, and these conduits can be rotated at any desired angle. Regarding the conduit pull elbow, given that the bend angle is 90 degrees or a right angle, this angle is created in the connecting part through precise assessments.
After that, the threading stages can be carried out on the part. In fact, the threads provide the conditions for the screwing operation to take place between pipes that have steel conduit couplings. Of course, there are also other techniques such as hot bending or induction bending, which some manufacturing companies use depending on the type of pipe and the equipment they have.
The conduit pull elbow essentially plays the role of guiding the flow of the conduit path. When a change of direction is needed in the electrical conduit network, this part is installed between two conduits at a specific angle (usually 90 or 45 degrees) so that the flow of cables continues without breakage or additional pressure. Using a conduit pull elbow not only simplifies the installation of conduits but also allows the cables to move safely and without damage along the curved path. This feature significantly increases the durability of the cables and the standardization of the conduit route.
Conduit pull elbows usually have several important features that make them worth purchasing more than ordinary elbows. A gentle bend, longer length, high resistance, and more simplify the function of this product. Among the most important features of these electrical conduit fittings, the following can be mentioned:
Has a gentle bend: These elbows have a gentler bend compared to the pull elbow, which prevents stress on the passing wires and cables.
Longer length: The length of these elbows is longer than ordinary elbows to create a safer path without worrying about wires and cables getting stuck.
High resistance: The resistance of these products is very high due to being made of steel and having a galvanized coating, and they can perform well in various environmental conditions.
Produced in standard angles: Conduit pull elbows are produced in standard angles of 45 and 90 degrees to provide the possibility of gentle and sharp changes of direction at corners.
Compatibility with various types of electrical conduits: Due to adherence to sizing standards, these elbows can have full compatibility with various types of electrical conduits and their dimensions.
Both conduit pull elbows and steel electrical conduits are manufactured with threads to enable their installation safely without the need for adhesive or welding. To connect a conduit pull elbow, it is first necessary to ensure the dimensional compatibility of the elbow with the electrical conduits, and then carry out the installation according to the following steps:
Preparing the threads: Before starting the installation, be sure to thoroughly clean the threads of the electrical conduit and the elbows so that there is no contamination, dust, or foreign objects on them.
Using Teflon tape: To tighten the elbows in the proper place, be sure to use Teflon tape around the threads.
Connecting the conduit to the elbow: Place the threads of the elbow and the conduit onto each other and tighten them by screwing. You can then tighten them as much as possible using an adjustable wrench or pipe wrench.
Ensuring the elbow is properly closed: After finishing the work, carefully inspect the connection point of the elbow and the electrical conduit once and ensure it is properly tightened and at the correct angle.
Passing wires and cables: Prepare the necessary wires and cables to pass through the electrical conduit and pass them through the appropriate path. Given the gentle bend of these elbows, you can easily pass the cables through them.
90-degree conduit pull elbow: To manufacture this product, the conduit is bent at a 90-degree angle, so that the two ends of the elbow will have a shape similar to a set square relative to each other. This product is used when the conduit needs a complete change of direction.
45-degree conduit pull elbow: To manufacture this part, the conduit is bent at a 45-degree angle. This fitting is used when the conduit needs a gentle change of direction or encounters a sloping bend.
The conduit pull elbow is one of the most widely used electrical conduit fittings, offered in the market with varying quality and price. Some people prefer to use cheap conduit pull elbows to save on costs; however, cheap fittings are not produced from resistant raw materials and will not have desirable resistance to pressure, impact, chemicals, etc. Therefore, we recommend that instead of buying a cheap and low-durability product, you obtain a high-quality conduit pull elbow at a reasonable price from Rafi Industrial Group. Due to direct production and supply, this group offers its products to customers at a more affordable price than other sellers.

Generally, for the preparation and production of steel electrical conduits, various methods such as hot-dip galvanizing or black paint coatings or cold galvanizing are used. The latter type is usually known as black steel conduit. However, regarding various types of steel electrical conduits and their fittings such as the conduit pull elbow, the strengthening method in the hot-dip galvanization process is the best and most ideal technique.
In fact, in the hot-dip galvanizing process, steel metals are strengthened using molten zinc coatings. This material provides the conditions for all structural defects and tiny internal and external pores of the metal to be completely coated with molten zinc material. The penetration power of this molten material is so high that it can even protect the metal structure against rust and corrosion for several years.
Numerous sizings of conduit pull elbows are designed and manufactured, each used according to the volume of cables as well as the size of the steel conduit. A very important point that we must always keep in mind is that the dimensions of this connecting part must be completely compatible with the size of the steel conduit, because the conduits are connected together with the elbows, and any size incompatibility will practically result in you being unable to use this conduit pull elbow. The dimensions and sizes available for conduit pull elbows are in sizes PG13.5, PG16, PG21, PG29, PG36, and PG48.
Of course, there are limitations in projects that cause users, depending on the type of electrical conduit project they have, to request custom dimensions and sizes, which manufacturing companies produce according to the established standards.
One of the valuable advantages that various steel conduit fittings such as conduit pull elbows, couplings, pull tees, conduit bodies, and other connecting parts have is that they are all designed and manufactured according to defined international standards. Therefore, you can be confident that these parts can maintain the safety of your cabling networks over a long period of time.
