What is the burst strength rating for recovery cylinders used with R-410A?

The burst strength rating for recovery cylinders used with R-410A is 400 psig. This rating indicates the maximum pressure the cylinder can withstand before failing. Recovery cylinders for refrigerants are designed with specific safety standards to ensure they can handle the operating pressures typically associated with various refrigerants, including R-410A.

R-410A operates at higher pressures than some other common refrigerants, and thus it is crucial that the recovery cylinders are rated appropriately to avoid catastrophic failures while handling the refrigerant. A rating of 400 psig provides an adequate safety margin for the pressures encountered during normal recovery operations. This also means that recovery cylinders must be manufactured from strong materials that can safely contain the refrigerant without bursting under high pressure conditions.

The other options present higher pressure ratings that would not be the standard for this type of recovery cylinder, as they exceed what is commonly necessary and recognized in industry standards for R-410A.
