In contrast to these traditional designs, every Zero-Leak Gold Banjo fitting assembly has two metal-to-metal seals, plus O-ring back-up seals. The primary metal-to-metal seals are designed to utilize the taper of the SAE J1926 and ISO 6149 port configurations to minimize gaps that occur due to axial movement associated with internal pressurization. Each engagement is several thousandths of an inch and generates high unit loading and maximum gap minimization between mating components during application of assembly torque. These design features combine to produce high-integrity metal-to-metal interfaces.
Furthermore, elastomeric seals (O-rings) act as “belt and suspenders” back-up seals for the metal-to-metal seals. There are two O-rings in each ZLG banjo fitting assembly. Both are positioned in machined recesses with cross-sectional areas greater than the cross-sectional areas of the elastomers they contain.
