The working principle of the press fitting is to insert the thin-walled stainless steel tube into the socket of the press fitting, and use a special pressing tool to fix the stainless steel tube in the fitting. There is an O-ring seal between them, which makes it have the characteristics of anti-leakage, anti-pulling, anti-vibration and high-pressure resistance. Therefore, it is a relatively advanced connector in piping systems such as direct drinking water systems, tap water systems, heating systems, and gas systems. It is suitable for pipeline connection of drinking water, tap water, natural gas, domestic hot and cold water, medical gas, fire fighting, etc.
Advantages of Compression Fittings
1. The section crimping is hexagonal, and the anti-rotation ability is improved;
2. The connection of double-pressed pipe fittings provides two resistance rings to improve the pulling force;
3. The double-pressed pipe fitting has a guide section to avoid the pipe from scratching the sealing ring;
4. The double-pressed sealing ring is completely sealed, which effectively improves the service life of the sealing ring;
5. The double card makes the bending resistance strong, and improves the ability to overcome the influence of external force on the pipeline.
