- Nara Vibration Absorbers are designed for installation in the suction and discharge lines of air conditioning and refrigeration systems to dampen the transmission of compressor-induced vibration through system piping.
- Nara are constructed of deep pitch corrugated tubing for increased flexibility and vibration absorption, covered by high tensile wire braid for superior strength.
- Tubing and braid are reinforced by ferrules at each end, and connected to female copper tube ends by high temperature braze alloys.
- Each Nara is pressure tested then carefully vacuum tested using a highly sensitive helium mass spectrometer leak detection device. 

- Hose and copper tube are braze welded.
- Cleaned and dehydrated for refrigeration service.
- Each unit pressure and vacuum tested, cleaned, dehydrated and sealed in plastic film.
- Complete physical and chemical analysis of all basic components.
- Size to fit 5/8" through 2 1/8" O.D. have a corrugated stainless core with high tensile stainless braid covering and copper tube ends.
- Components checked and inspected at various phases of assembly.
- Ends accurately sized.
- Final inspection.
