Abstract
A fluid injector includes a housing and an inlet tube having a portion received in the housing. A primary seal creates a seal between surfaces of the housing, the inlet tube, and an inlet of the injector. A groove is in the housing and a secondary seal is in the groove to defining a seal between the housing and a portion of the inlet of the injector. A recessed portion is defined in the housing and is in communication with the groove. The recessed portion defines a blow-out volume such that when the primary seal is leak tested, an indication of a leak of the primary seal can be detected when the pressurized air moves past the primary seal and forces a portion of the secondary seal to an unsealed position into the blow-out volume.
