The meanning of double ball rubber joints
Rubber joints, also known as flexible rubber joints, rubber soft joints, soft joints, flexible rubber joints, rubber expansion joints, shock absorbers, etc., are pipeline connectors with high elasticity, high airtightness, medium resistance, and weather resistance.
Performance characteristics of double ball rubber joints
Rubber joints utilize the advantages of high elasticity, high gas resistance, medium resistance, weather resistance, and radiation resistance of rubber, which can reduce pipeline vibration and noise, and compensate for thermal expansion and contraction caused by temperature changes.
Product advantages
1. The sphere is longer and has better vibration and noise reduction effects
2. Good telescopic displacement performance and longer service life than single ball rubber joints
3. Small size, light weight, good flexibility, and convenient installation and maintenance
4. Absorbable displacement after installation
5. Reduce noise
