5 Types of Compression Fittings and Their Uses

Compression Fittings

Compression fittings are widely used in plumbing, offering efficient, reliable, and leak-proof connections between pipes and plumbing fixtures. These fittings are available in various types, sizes, and materials to cater to diverse applications. However, not all compression fittings are the same, and choosing the right one for your plumbing job can be confusing. This blog post aims to help you understand the types of compression fittings available in the market, their applications, and how to select the right one for your needs.

Compression Sleeve Fittings

Compression sleeve fittings, or ferrule fittings, are the most popular type. They comprise a compression nut, ring, and a brass or stainless-steel sleeve. When the nut is tightened, the call is compressed around the pipe, creating a solid seal. Compression sleeve fittings are suitable for metal and plastic pipes and ideal for frequent disassembly applications.

Straight Coupling Fittings

Straight coupling fittings join two straight pipes of the same size. They have a compression nut and a brass or stainless-steel body that houses the compression ring. When the nut is tightened, the ring compresses tightly around both pipes, creating a strong, leak-proof seal. Straight couplings are ideal for connecting two lines that must be separated frequently.

Elbow Compression Fittings

Elbow compression fittings are used to connect pipes that are at an angle or are not straight. Instead of having a straight body like the straight coupling fitting, they have an angled body, usually at a 90-degree angle. These fittings come in various grades, like 45 and 90 degrees. They are commonly used in household plumbing systems for connecting fixtures and appliances that require a change in direction.

Tee Compression Fittings

Tee compression fittings are used to connect three pipes of the same size. They have a compression nut, brass or stainless-steel body, and three compression rings. The three rings compress around the pipes when the nut is tightened, creating a strong, leak-proof seal. These fittings are commonly used in split pipe systems and appliances that require an additional water supply.

Union Compression Fittings

Union compression fittings connect two pipes that must be attached permanently or require less frequent disassembly. They consist of a union nut, two compression rings, and a brass or stainless-steel body. The rings compress against the pipes as the nut is tightened, forming a solid seal. These fittings are commonly found in gas and water supply systems.

Conclusion

Compression fittings are available in various sizes, materials, and shapes, making them highly versatile in plumbing applications. However, selecting the right type and size of compression fitting is crucial for ensuring optimal performance. Knowing the specific plumbing requirements, conditions, and materials is essential to choose the appropriate compression fitting. By understanding the types of compression fittings available and their uses, you can make an informed decision and choose the right one for your plumbing job.
