- 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. |
