Lubrication Hoses and Rigid Feed Tubes for precise lubrication

The secure delivery of lubricants from the pumping device to the lubrication point is a critical factor in maintenance. Lubrication hoses and extension tubes function as media-conveying bridges that must withstand high operating pressures while enabling precise positioning at the grease nipple. ABNOX provides technically optimized solutions for this purpose, designed for maximum burst safety and chemical resistance to industrial greases and oils.

• Connection Threads:
  Standardized thread forms (e.g., G 1/8", M10x1) with high flank precision for leak-free connections.
• Burst Safety:
  All hoses are specified with a high safety factor (P_burst)) relative to the nominal operating pressure (P_working).
• Corrosion Protection:
  Use of surface-finished steels or high-performance plastics to prevent material fatigue caused by aggressive cooling lubricants.
• Flow Optimization:
  Smooth inner walls minimize media frictional resistance, which reduces the required effort, especially with high-viscosity greases (NLGI 2/3).

By using ABNOX lubrication hoses and extension tubes, you eliminate weak points in the lubrication circuit. The robust design prevents hose bursts and the resulting contamination or personal injury. The exact synchronization of the connection technology guarantees loss-free media transfer, which increases the efficiency of lubricant use and extends the service life of the lubricated bearings.

At pressures of up to 400 bar (approx. 5,800 psi) and above, lines must not exhibit any significant volumetric expansion to guarantee exact metering. The choice between flexible hoses and rigid tubes depends primarily on the accessibility of the lubrication point and the required back-pressure.
 

Technical Overview of Product Categories:

High-Pressure Armored Hoses:

Flexible armored or high-pressure hoses with multi-layer reinforcement (e.g., steel wire braid). These lines allow for lubrication in hard-to-reach areas and absorb vibrations between the pump and the application point. They are characterized by tight bending radii combined with high pressure resistance.
 

Extension Tubes:

Rigid versions made of galvanized steel or stainless steel. Extension tubes are used when exact guidance of the nozzle under high mechanical pressure is required. They offer maximum stability and are available in various lengths and angles (curved or straight) to safely reach deep-seated lubrication points.
 

Swivel and Articulated Joints:

A specialized solution that combines the stability of a tube with the flexibility of a hose. By using joints, these lines can be moved into exact positions and maintain them even under load – ideal for stationary systems or fixed lubrication units.
