Connectors for lubricants and mineral oil

In professional lubrication technology, couplers form the direct mechanical interface between the grease gun and the grease nipple. The primary task of these components is to establish a pressure-tight and positive connection to deliver lubricating greases or oils into the bearings without loss. ABNOX couplers are designed for high operating pressures and ensure safe handling, even under the extreme conditions of industrial maintenance.

A coupler must be capable of overcoming the high backpressure of the lubrication point without the medium leaking from the sides. Especially in the case of resinified or blocked lubrication points, enormous pressure peaks occur for short periods. High-quality couplers are characterized by hardened gripping jaws and precisely matched sealing elements that prevent popping off under load and ensure contamination-free media transfer.
 

Product Specification

Manufactured from high-strength, surface-finished steel for maximum service life. The range includes various designs, from standard 4-jaw hydraulic couplers for hydraulic-type (tapered) nipples to specialized versions for button-head, flush, or cup-style fittings. The integrated high-performance seals are optimized for chemical resistance against mineral oils and synthetic lubricants. Massive spring and gripping mechanisms guarantee reliable locking on the nipple head and allow for controlled decoupling after the lubrication process.

• High-Pressure Integrity: 
  Validated for use with lever-action, one-hand, and pneumatic grease guns at pressures up to 400 bar.
• Hardened Gripping Jaws: 
  Low-wear contact surfaces ensure a secure grip on the grease nipple, even with high frequency coupling cycles.
• Precision Threads: 
  Standardized connection threads (e.g., G 1/8" or M10x1) allow for easy mounting on extension pipes or high-pressure hoses.
• Compact Design: 
  Optimized outer diameters allow access to deep-seated or narrowly installed lubrication points in complex machine designs.

The use of ABNOX couplers reduces lubricant consumption and prevents contamination of the machine environment. Reliable sealing ensures that the defined amount of lubricant actually reaches the bearing, which massively increases the service life of the tribological chain. The robust design minimizes the risk of mechanical failure at the interface, thereby increasing the efficiency of maintenance processes and optimizing occupational safety for personnel. Consequently, these components form the technological endpoint for process-reliable lubricant application.
