Metric Banjo Fitting Elbow - Centralized Grease Line Bolt Couplings

Our Metric Banjo Fitting Elbow is the industry standard for distributing lubricants safely through high-frequency automatic lubrication and centralized grease systems. Engineered with a low-profile annular ring body and a dedicated hollow male bolt, this 90-degree swivel-capable connector attaches a single metric line directly to a machine or block port. By allowing full 360-degree orientation alignment before final tightening, it eliminates wide tube bending loops, protects lines from stress in tight spaces, and coordinates secure grease delivery to progressive distribution blocks.

As a high-volume B2B manufacturer and global OEM supplier, we construct our grease line compression fittings on automated multi-axis precision lathes to guarantee flawless cross-hole drilling, optimal internal flow curves, and exact thread profiles on every hollow bolt. Every production lot is subject to rigorous quality control auditing to ensure absolute structural stability under the severe, pulsing pressures common in automated lubrication networks.

Core Technical Blueprint & Symmetric Engineering

• Optimized for LL Series Networks: Purpose-built for the Extra Light (LL) Series footprint, this elbow banjo coupling handles operating thresholds up to 100 bar, aligning seamlessly with the pressure boundaries of commercial grease lines (machined for small-diameter tubing from 4mm to 12mm). Its minimized mass and compact profile ensure clean, low-clearance mounting inside crowded machinery panels and moving chassis joints.

• Symmetric Angle Alignment Design: The tube entry point features a standard 24° internal cone tube seat machined to the same metric specifications as your main line. The design allows the installer to pivot the fitting smoothly around the hollow male bolt to achieve the perfect exit angle before securing the mechanical connection.

  • Identical Metric Connections: Integrates directly with standard metric lubrication tubing loops globally, ensuring an exact, localized fit without line modification.

Application & Compliance Standards

• Single Bite Sealing Integrity: Tightening the compression nut drives the specialized cutting ring forward into the body seat, forcing it to bite cleanly into the exterior surface of the copper, steel, or high-pressure nylon tubing. Simultaneously, torque on the hollow male bolt compresses the sealing washers tightly against the port face. This dual-point mechanical connection creates an unyielding seal that easily withstands high industrial vibrations, continuous machine cycling, and pressure shocks.

• Global Interchangeability: Manufactured in strict conformity with ISO 8434-1 and DIN 2353 extra-light guidelines. These elbow banjo couplings offer complete, drop-in compatibility with leading international fluid-handling brands. They serve as the trusted default choice for commercial vehicle chassis, wind turbine bearings, progressive distribution blocks, heavy mining machinery, and automated industrial assembly systems.
