Flexible Connector Single Rubber Bellows | Vibration Absorbing Expansion Joint
Product Overview
The Flexible Connector Single Rubber Bellows is a high-performance pipeline connection solution designed to absorb vibration, reduce noise, and compensate for pipe displacement. Made of premium elastomer materials such as EPDM, NBR, or Neoprene, this single bellows expansion joint offers excellent flexibility and durability, making it suitable for a wide range of industrial and commercial applications.
Its compact design ensures easy installation, while the reinforced layers and flanged ends provide secure sealing and long service life under various pressure and temperature conditions.
High Flexibility – Effectively compensates for axial, lateral, and angular displacement in pipelines.
Vibration & Noise Reduction – Minimizes mechanical stress from pumps, compressors, and other vibrating equipment.
Durable Construction – Manufactured with reinforced rubber layers and steel flanges for enhanced safety.
Corrosion & Weather Resistance – Suitable for water, oil, gas, chemical solutions, and outdoor environments.
Easy Installation & Maintenance – Compact single-bellows design requires minimal space and reduces downtime.

FAQ
Q1: What is the main purpose of a single rubber bellows with a flexible connector?
A: It absorbs vibration, reduces noise, and compensates for thermal expansion or misalignment in the pipe.
Q2: Can chemically resistant materials be customized?
A: Yes. We offer natural rubber (NR) for domestic water, ethylene propylene diene monomer (EPDM) for acid and alkali resistance, nitrile rubber (NBR) for oil resistance, and fluororubber (Viton) for high-temperature resistance.
Q3: How do I choose the right size?
A: Please provide your pipe diameter, operating pressure, temperature, and media. Our technical team will recommend the appropriate specifications.
Q4: What is the average service life?
A: Typically 5-10 years, depending on operating conditions and maintenance.
