Vibration-Resistant Metal Bellows Hose for Compressors in Cold Storage & AC Refrigeration Systems
Product Description
The Vibration-Resistant Metal Bellows Hose is a premium-grade flexible connector designed specifically for compressors, condensers, and refrigeration units in cold storage and air-conditioning systems. Engineered to absorb vibration, compensate for thermal expansion, and reduce noise, this hose ensures system stability and prolongs the service life of connected components.
Constructed with corrugated stainless-steel tubing and high-strength copper or brass fittings, it provides excellent mechanical durability, corrosion resistance, and long-term reliability, even in demanding industrial or commercial refrigeration environments.
Product Features
- High Flexibility & Vibration Absorption
The bellows structure efficiently isolates compressor vibration and system pulsation, preventing transmission to the pipeline.
- Durable Stainless-Steel Construction
Manufactured using SUS304 or SUS316L stainless steel, ensuring exceptional resistance to corrosion, fatigue, and high pressure.
- Leak-Proof & Secure Connections
Precision-welded ends with copper or brass fittings guarantee tight sealing performance, suitable for refrigerants such as R22, R134a, R404A, and R410A.
- Thermal Expansion Compensation
Absorbs thermal expansion and contraction caused by temperature changes in the system, preventing stress or damage to equipment.
- Wide Temperature & Pressure Range
Suitable for continuous operation under extreme temperature variations and high working pressures, ensuring consistent performance and safety.
Application Scenarios
The metal bellows hose is widely used in commercial refrigeration, cold storage warehouses, HVAC systems, air compressors, and refrigeration transport vehicles.
It serves as a critical flexible joint between the compressor discharge/suction ports and the fixed pipeline, reducing vibration-induced fatigue, leakage risks, and maintenance frequency.
Applicable for Carrier, Thermo King, Daikin, Midea, and Bitzer systems, as well as customized refrigeration assemblies.
