Compression Fittings (or Compression Coils)
Compression fittings are pipe fittings primarily composed of two ferrules: an inner ferrule, typically made of metal, and an outer ferrule, made of rubber or plastic. The inner ferrule's function is to secure the pipe and provide a seal. Its outer arc shape ensures proper pipe insertion and prevents leakage. The inner ferrule also has a raised sealing groove for installing a sealing ring.
Sealing Ring
The sealing ring is a crucial component of compression fittings, maintaining the pipe's sealing performance. Generally made of rubber or silicone, it effectively prevents leakage. The sealing ring is usually annular and placed within the sealing groove of the inner ferrule, forming a sealing layer between itself and the pipe.
Wire Mesh
Wire mesh is an important component of compression fittings. It forms a layer of wire mesh covering the sealing groove of the inner ferrule. Its function is to enhance the strength and rigidity of the ferrule, preventing deformation. The wire mesh increases the installation force and compressive strength of the inner ferrule, ensuring the correct use of the compression fitting.
Installation Method
When installing compression fittings, first ensure that the pipe end face is accurately perpendicular. Next, insert the inner ferrule into the pipe, ensuring it is properly seated. Then, place the sealing ring over the inner ferrule and lay the wire mesh over it. At this point, the outer ferrule can be inserted between the inner ferrule and the wire mesh, ensuring the ferrule connector's stability. Finally, press the ferrule connector to ensure it is fully installed.
