Product Introduction
Thread double ball rubber soft joints are commonly known as flexible rubber joints, the main materials are neoprene, natural rubber and EPDM rubber, and the rubber soft joints can be automatically extended due to natural changes in weather. Threaded connectors can be flexible rubber joints, which can be connected by any shock absorbing throat, etc., and are a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The threaded rubber soft joint makes use of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of rubber, and is made of polyester cord with high strength and strong cold and heat stability after being diagonally compounded with it, and then vulcanized by high-pressure and high-temperature molds.
Product material selection
The materials of threaded rubber joints include carbon steel, 304 stainless steel, 316 stainless steel and other metal materials, as well as natural rubber, EPDM rubber, nitrile rubber, butyl rubber and other rubber materials. The selection of these materials depends on the nature of the fluid in the pipeline, such as acid resistance, alkali resistance, oil resistance, heat resistance and other requirements
Product structure composition
The threaded rubber joint is composed of an inner rubber layer, a multi-layer nylon cord reinforcement, an outer rubber layer and a metal union joint. Its connection method is threaded connection, which is usually called threaded rubber joint, fan coil unit rubber soft connection, thread buckle rubber soft connection, etc.

Different types of rubber joints
How to install the product
1. Preparation: Make sure the pipes and joints are clean, and check if the rubber seals are intact.
2. Determine the location: Determine the installation location of the joint according to the position of the connected pipe or equipment, and measure the diameter of the pipe as needed.
3. Install the rubber seal: Place the rubber seal at the pipe port or equipment connection. Make sure the seal completely covers the connection and is not twisted or damaged.
4. Connecting joints: Align the threads of the wire mouth part of the joint with the threads at the connection of the pipe or equipment, and tighten until it is fully connected. If needed, you can use a wrench or other tool to tighten it, but be careful not to use excessive force to avoid damaging the joints or pipes.
5. Inspection and test: After the installation is completed, you should check whether the joint is firm and rule out water leakage. In the case of a water supply system, a hydrostatic test can be performed to ensure that the fitting is completely sealed.
Product installation precautions
1. Visual inspection: Before installation, the appearance of the rubber joint should be carefully checked to ensure that there are no obvious breakages, cracks or other defects. The thread part should be intact, and there should be no rust or other foreign matter at the thread fastener.
2. The use of threaded sealing tape: During the installation process, the threaded sealing tape is first wound around the threaded part of the joint, which usually needs to be wound 3 to 4 times to ensure that each circle is evenly fitted and avoid leakage. The function of the sealing belt is to prevent small leaks at the joint connection and enhance its sealing performance.
3. Tighten evenly: Use a wrench to align the threaded part of the threaded rubber joint with the threaded interface of the pipe, and then rotate it slowly. Do not use too much force to prevent damage to the threads or deformation of the joint. During the rotation process, it is necessary to keep the thread smooth to prevent the occurrence of jamming.
4. Avoid over-tightening: Although the joint needs to be secure, over-tightening may cause the rubber joint to be deformed or the thread to be damaged, which in turn will affect the sealing effect.
5. Adjust the angle of the joint: After the installation, the angle of the threaded rubber joint can be adjusted according to the actual needs to ensure that the pipeline connection is stable and tight. If the position of the joint is found to be unsatisfactory during the installation process, it should be adjusted in time to avoid connection failure.
