Are you struggling with the high pressure and corrosiveness of carbon dioxide (R744) refrigeration systems?
Ordinary vibration absorbers often fail under high pressure or corrosive conditions. Honway's All SS Vibration Absorber is specifically designed for high-pressure and carbon dioxide applications.

Professional-grade natural refrigerant vibration damping solution: Honway's All SS Vibration Absorber is designed to meet the demanding requirements of modern refrigeration systems, especially suitable for carbon dioxide (R744), ammonia (R717), and high-pressure R410A systems. Unlike standard copper-end vibration absorbers, our all-stainless steel construction ensures a leak-free, corrosion-resistant solution for transcritical and subcritical cycles.
Maximum Operating Pressure: Varies from 60 bar (870 psi) to 20 bar (290 psi) depending on connection size. (High-pressure custom models up to 120 bar are also available for transcritical CO2 systems).
Operating Temperature Range: The CO2 Vibration Absorber is suitable for temperatures from -40°C to +120°C, maintaining excellent ductility and strength under extreme thermal cycling.
Materials: Bellows, braided layers, and ferrules are made of high-grade SUS304/316L stainless steel.
Testing: 100% helium and hydrogen leak testing ensures absolute sealing.
Compatibility: Fully compatible with R744 (CO2), R717 (ammonia), R410A, and other natural/synthetic refrigerants and their matching lubricants.

Standard SUS304:
For most CO2 (R744) and commercial refrigeration applications, SUS304 offers the perfect balance of performance and value.
Optional SUS316L (Project-Based Customization):
For projects with even more demanding requirements, we provide AISI 316L Stainless Steel as a premium customization option. Due to specific raw material procurement, 316L is available for volume-based orders.
Note: Please contact our sales team to discuss MOQ and lead times for 316L customized orders.
Pipe Vibration Absorber - Designed for R744 (CO2):
The Pipe Vibration Absorber is made entirely of stainless steel, corrosion-resistant, eliminating the risk of copper-steel galvanic corrosion.
Precision TIG Welding: Each Pipe Vibration Absorber undergoes a rigorous TIG welding process. Unlike brazing, our welding process maintains material integrity and prevents leaks at high temperatures.
Helium Leakage Testing: Each device undergoes a 100% vacuum test using a helium gas spectrometer to ensure absolute sealing.
Clean and Dry: After rigorous cleaning and dehydration, suitable for refrigeration applications and compatible with POE/PAG oils.
Customized Braided Hose Vibration Absorber Services: We offer customized services for each customer, tailoring detailed parameters to your drawings, including the length of the refrigeration all SS vibration absorber, special end fittings, and special braided layers suitable for high-pressure enhanced environments.
· You provide drawings, detailed parameters, and requirements, and we will customize the most suitable damping tube for your project.

Q: Why are the maximum operating pressures varying from 60 bar to 20 bar?
A: In refrigeration systems, as pipe diameter increases, the allowable pressure typically decreases to ensure a safety margin. Our smaller sizes (1/4” to 7/8”) are rated at 60 bar, while our largest industrial size is rated at 20 bar. However, for CO2 systems requiring higher pressures, we offer custom-designed enhanced products.
Q: Can these absorbers handle the risk of "dry ice" in CO2 systems?
A: Yes. We chose SUS304/316L materials precisely because of their cryogenic performance. Even when the system experiences rapid pressure drops leading to low temperatures, they remain robust and durable, avoiding the "cold brittleness" common in inferior materials.
Q: Are Honway shock absorbers certified?
A: Yes, our products are UL and CE certified, ensuring compliance with global pressure equipment safety standards.
Whether you need standard pipe vibration absorbers or complex custom engineering solutions, our team is ready to assist you.
