Overview

 Female threaded threaded rubber couplings are ideal for isolating small diameter piping from vibrating mechanical equipment.
In smaller size applications where threaded connectors are normally used,  Female threaded threaded rubber couplings will accommodate both pipe motions and vibration. Female threaded threaded rubber couplings will provide over 1” of axial compensation, as well as impressive ratings for lateral and angular deflection. The Neoprene or EPDM rubber body construction is also far superior to metallic connectors for eliminating noise and vibration generated by equipment such as pumps, chillers, and air handlers. These connectors are extremely versatile and can be used in a variety of services, and are available in designs to handle up to 150 PSIG and temperatures up to 200 degrees F.
Female threaded threaded rubber couplings are precision molded in hydraulic presses. The spherical design ensures that internal pressures are exerted in all directions, distributing the forces evenly over a large area. The spherical design acts as a free-flowing arch, reducing turbulence and growth due to pressure thrust forces.
Female threaded threaded rubber couplings are constructed with a high-quality EPDM tube and cover and nylon tire cord reinforcing. Neoprene construction without cables is also available.
Female threaded threaded rubber couplings offer high-temperature EPDM rubber for tube and cover construction. Galvanized ductile iron threaded female union ends are standard. Special cable restraint attachments surround each end to prevent the connector from over-extending due to pressure thrust. A steel body ring encircles the rubber between the spheres to provide stability under pressure.

 

Features

Flexible joints introduction: 

1. This product can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.

2. By using different materials, it can be made many kinds to cater for different medium and environment. Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.

3. The material is pure rubber, sealing is very good. It is in light weight, very easy for installation . This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere. 

4. The product can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry,
