Banjo Testing Couplings

Sealant Enterprises is the best manufacturer and supplier of Banjo Testing Couplings. Standard washer-dependent banjo connectors and couplings, as well as banjo hydraulic, pipe and hose fittings, attempt to create a seal with washers, which is difficult and virtually impossible to reseal reliably.

They typically have poor resistance to vibration and require high assembly torque, possibly resulting in stripped threads and tensile failure of bolts.

The components require fine surface finishes on port faces and banjo seats, and flow characteristics are obtained through the difficult and expensive process of recessing bodies.

The banjo testing coupling washers may also fall off and can be difficult to handle during assembly. This design has 4 separate leak paths

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 the application of assembly torque. These design features combine to produce high-integrity metal-to-metal interfaces.
