High-Pressure Lubrication Banjo Fittings for Construction Vehicles | Fitsch

Protect your automated grease lines from mechanical impacts and tight-clearance kinking with our heavy-duty Fitsch central lubrication banjo fittings for construction vehicles. Specifically engineered for the extreme articulations of excavators, wheel loaders, dump trucks, and bulldozers, these right-angle ring-piece couplings allow high-pressure lubrication hoses to sit completely flush against structural steel frames. By eliminating protruding loops and sharp bends, they shield your progressive distribution system from falling debris, brush snags, and crushing forces while handling operating pressures up to 400 bar (5,800 PSI).

Industrial Performance Features

• Ultra-Low Profile Right Angle Design: Solves severe physical space limitations around oscillating axle pins, boom hinges, and bucket linkages where traditional 90-degree elbows are too vulnerable to damage.

• 360-Degree Swivel Alignment: The ring piece configuration rotates freely around the internal fluid pass-through bolt during initial assembly, allowing you to route high-pressure nylon or steel tubing at the exact angle required before final torquing.

• Vibration-Proof High-Pressure Seal: Equipped with high-tensile metal-to-metal sealing edges or heavy-duty elastomeric washers that survive the persistent shock profiles, hammering actions, and structural vibrations of mining and quarry job sites.

• Heavy-Duty B2B Protective Coating: Machined from high-strength forged steel with premium zinc-nickel plating to withstand aggressive chemical washdowns, mud packs, salt exposure, and abrasive track grit.

Technical Specifications & Fitting Compatibility

Our high-volume construction vehicle lubrication banjo inventory is built for:

• Thread Options: High-tensile Metric (e.g., M6x1, M8x1, M10x1) and standard BSPP parallel banjo bolts.

• Tube Connections: Compression cutting ring, push-in, or high-pressure hose stud variations for 4mm, 6mm, and 8mm lubrication lines.

• Equipment Applications: Tailor-made for heavy off-road machinery brands including Caterpillar, Komatsu, Volvo, Hitachi, and Liebherr automatic lubrication loops.
