Zero-Leak Gold Banjo Fittings
Multiple seals distinguish the Zero-Leak Gold® Banjo Fitting from traditional Banjo fittings. Two separate and independent seals form a double redundant sealing system. A primary metal-to-metal seal works in conjunction with an elastomeric back-up seal to create a zero-leak connection.
Typical applications include:
- Diesel Engines
- Automotive Brake Systems
- Air Conditioning Systems
- Power Steering Systems
- Agricultural Equipment
- Construction Equipment
- Robotics
Problems with standard banjo fittings:
- Attempting a seal with sealing washers is difficult, and it's virtually impossible to reseal reliably.
- Poor resistance to vibration.
- High assembly torque is required, possibly resulting in stripped threads and tensile failure of bolts.
- Components require fine surface finishes on port faces
and banjo seats. - Flow characteristics are obtained through the difficult and expensive process of recessing bodies.
- Sealing washers fall off and are difficult to handle during assembly.
ZLG Banjo Fittings Benefits:
A: metal-to-metal seal
B: elasometric back-up seal
- Separate seals provide long-term protection against weeps and leaks.
- Can be designed for custom ports as well as Standard SAE and ISO ports.
- Significant cost reductions in most applications.
- Wide range of assembled torque values.
- Reseal repeatedly.
- Withstands vibration, temperature variation and pressure spikes.
- No copper washers required.
