Features of the 90-Degree One Coupling-End Elbow
The 90-degree one coupling-end elbow is an essential and widely used fitting in plumbing and sewage systems, designed to create a precise 90-degree change in the direction of fluid flow.
Design Features and Construction Materials
The 90-degree one coupling-end elbow is often made of resistant polymer materials such as UPVC, and therefore, it has high resistance against corrosion, rust, and the effects of household chemicals. One of the design advantages of this product is its easy and quick connection. This rapid connection significantly reduces execution time and costs, especially in large projects, while ensuring the system’s watertightness.
Applications in Installations
The main application of the 90-degree one coupling-end elbow is in networks that require a sudden and perpendicular change in direction, some of which are mentioned below:
Domestic and building sewage systems
Water supply systems
Confined spaces for plumbing
Distinction between One Coupling-End and Two Coupling-End 90-Degree Elbows
The main difference between the 90-degree one coupling-end elbow and the 90-degree two coupling-end elbow is the number of connection ends equipped with a coupling.
90-Degree One Coupling-End Elbow: This model has a ready-made socket (female end) for easy connection on only one side, and the other side is designed as a plain end (male end) or for other connection methods. This elbow is used in situations where only one side of the connection requires quick coupling capability.
90-Degree Two Coupling-End Elbow: This model has a socket (female end) on both sides, allowing the plumber to quickly connect pipes from both sides without the need for glue or welding (especially in push-fit fittings). This feature makes this elbow an ideal choice for networks where installation speed and the modularity of all fittings are vital.
This product has one female end (one coupling end) and one male end (spigot end).
