Key Features
High-Pressure Integrity: Engineered to withstand extreme operating and burst pressures without structural failure.
Absolute Leak Prevention: Precision sealing technology prevents hydraulic oil and grease seepage under high loads.
Corrosion Resistance: Manufactured from heavy-duty, corrosion-proof materials for harsh outdoor environments.
Vibration Stability: Robust locking and threading design resists loosening caused by continuous machinery vibration.
Universal Compatibility: Designed to integrate seamlessly with standard global hydraulic and lubrication piping networks.
Applications
Centralized Lubrication: Integrated into progressive and single-line automatic lubrication systems for fixed industrial machinery.
Heavy Machinery: Extensively used in construction excavators, mining equipment, and agricultural harvesters.
Hydraulic Systems: Applied in power units, control blocks, and heavy hydraulic press lines.
Automotive & Fleet: Essential for commercial vehicle chassis and industrial transport equipment lubrication lines.
Thread & Connection Options
Metric Threads: Precision-machined M10×1, M6×1, and metric straight/tapered options for European and Asian plant standards.
Imperial Threads: Standard G1/8, G1/4, G3/8, and NPT profiles widely utilized in North American and global hydraulic circuits.
Special Connections: Custom port configurations, banjo fittings, and specialized swivel adapter joints built to engineering blueprints.
Pressure Rating & Leak Prevention
High-Pressure Capability: Built for heavy-duty lubrication lines operating under high pump output and continuous pressure surges.
Reliable Sealing Barriers: Combines tight thread tolerances with resilient sealing materials to completely eliminate external oil weepage and grease blow-by.
Pressure Retention: Maintains stable line pressure across distribution networks to ensure accurate grease volume delivery to every bearing point.
Our Service
Surface Preparation: Ensure mating threads and port surfaces are entirely clean and free of metal shavings or grit.
Thread Sealant Application: Apply appropriate thread sealant or utilize integrated O-ring seals per the specific joint design.
Torque Specification: Tighten to recommended torque guidelines to achieve proper seal compression without stripping threads.
System Testing: Pressurize the lubrication line gradually and inspect all joint connections for leaks before full operation.
Standards & Quality Control
Rigorous Quality Assurance: Produced under strict ISO-certified manufacturing controls from raw material casting to finished plating.
Performance Testing: Every production batch undergoes hydrostatic pressure testing, thread tolerance verification, and leak testing.
Durability Compliance: Designed and manufactured to meet global industrial standards for fluid power and lubrication components.
