Refrigeration Vibration Absorbers
Flexible vibration absorbers for refrigeration and HVAC piping systems. The braided flexible section is designed to help isolate compressor vibration and reduce vibration transmission through connected piping. Select the required size from the dimensional and pressure table below.
Product Overview
Product: Refrigeration Vibration Absorber
Application: Refrigeration and HVAC piping systems
Nominal size range: 1/4" to 4-1/8"
Metric ID range: 6 mm to 105 (108) mm
Working pressure: Up to 650 psig, depending on size
Burst pressure: Up to 3250 psig, depending on size
Construction & Function
The flexible braided section is installed in-line between rigid piping sections to help absorb vibration and movement generated by compressors and other refrigeration equipment. Copper tube ends allow integration into refrigeration piping assemblies.
For correct selection, confirm the nominal tube size and compare the A, B, C, D and E dimensions with the available installation space. Pressure ratings vary by size, so use the complete specification row when requesting a quotation.

Frequently Asked Questions
What sizes are available?
The supplied specification table lists nominal sizes from 1/4" through 4-1/8", with corresponding metric ID values.
Are the pressure ratings the same for every size?
No. Working and burst pressure ratings decrease on the larger listed sizes, so the correct row should be checked for each selected size.
What information should I provide for a quotation?
Please send the nominal size, quantity, destination and any installation or replacement dimensions that need to be matched.
