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
