High-Pressure Hoses & Hose Studs for Automatic Lubrication Systems
Maximize the life and efficiency of your machinery with our premium range of high-pressure lubrication hoses and precision-engineered hose studs. Specifically built for automated grease and oil lubrication networks, our fluid-conveying components provide a leak-free, high-durability conduit for progressive, dual-line, and single-line lubrication systems.
As a leading professional manufacturer, we engineer our lines to surpass standard market offerings, delivering superior flexibility, burst resistance, and uninterrupted flow to critical bearings, pins, and bushings.
Why Choose Our High-Pressure Lubrication Hoses?
Automatic lubrication systems operate under extreme pressure surges and aggressive environmental exposure. Our advanced multi-layer hose architecture is designed to handle these demands flawlessly.
Advanced Reinforced Architecture: Built with a high-grade polyamide (PA) inner tube encased in a high-tensile polyester reinforcing mesh and fused to a rugged, abrasion-resistant polyurethane (PU) outer jacket.
Industrial-Grade Pressure Performance: Engineered for absolute safety under heavy loads, our premium hoses deliver a continuous working pressure rating of 600 bar and a maximum cracking/burst pressure threshold of 840 bar (84 MPa / 12,184 PSI) at 20°C.
Excellent Tight-Bend Flexibility: Optimized to provide a permissible bending radius down to 20 mm (for DN4 lines), allowing for effortless routing through tight articulations, moving machine parts, and complex manifold junctions.
Pre-Filled or Unfilled Options: Available empty or pre-filled with high-performance NLGI Class 2 grease to streamline your installation process and prevent air pockets in your lines.
Heavy-Duty Hose Studs & End Fittings
A high-pressure system is only as reliable as its connections. Our precision-machined hose studs, screw sleeves, and end fittings ensure a rock-solid, leak-proof seal without the need for specialized hydraulic crimping tools.
Tool-Free Field Assembly: Designed to accept standard screw sleeves and tube studs. Installations can be completed quickly on-site using conventional box spanners.
Anti-Corrosive Metallurgy: Extruded from high-grade carbon steel with an advanced zinc-nickel anti-corrosion coating, or from 304/316 stainless steel to withstand harsh industrial and marine conditions.
Universal Network Integration: Available in straight, 45-degree, and 90-degree configurations featuring Metric, BSP, and NPT threads for plug-and-play compatibility with any major central lubrication pump or distribution block.
