Product Features

Double sealing guarantee: 

Two independent rubber sealing rings are designed to form a double sealing barrier, which greatly improves the sealing and safety of the connection parts. Even if one sealing ring fails, the other can still maintain the sealing effect.

High-quality materials: 

Made of high-strength PVC-U material, it has excellent corrosion resistance and can resist the erosion of most acids, alkalis, salts and other chemical substances, with a service life of more than 50 years.

Accurate angle design: 

The 90-degree bend is precisely calculated and manufactured to ensure smooth fluid diversion, reduce turbulence and pressure loss, and maintain efficient operation of the system.

Easy installation: 

Socket connection design, no special tools or welding are required, and installation can be completed by simply pushing it in, which greatly saves construction time and labor costs.

Good seismic performance: 

The rubber sealing ring has a certain elasticity and can absorb the displacement and vibration of the pipeline system caused by temperature changes or external forces, reducing system stress.

Strong adaptability: 

Suitable for various environmental conditions, including underground burial, open-air installation and indoor pipeline systems, with an operating temperature range of -20℃ to 60℃.

Standardized production: 

Produced strictly in accordance with international standards (ISO 1452) and national standards (GB/T 10002.1) to ensure product quality and interchangeability.

FAQ

Q1: What is the difference between double rubber ring elbow and single rubber ring elbow?

A1: The double rubber ring design provides double sealing protection and higher reliability, especially for applications with large pressure fluctuations or strict sealing requirements.

Q2: Is it suitable for hot water systems?

A2: It can be used for hot water systems ≤60℃, but long-term high temperature will affect the product life. It is recommended to use high temperature resistant models.

Q3: How to test after installation?

A3: It is recommended to perform a hydrostatic pressure test at 1.5 times the working pressure for ≥30 minutes. No leakage is qualified.

Q4: Product service life?

A4: Under normal conditions, the design service life is more than 50 years. The actual service life depends on the use environment and maintenance.

Q5: How to choose the right size?

A5: Choose according to the system design pressure, flow rate and medium characteristics. If you have any questions, please consult our technical support.
