DIN 71412 specifies metric grease fittings designed for secure, high-pressure lubrication in industrial and automotive systems. These fittings feature a straight thread design (e.g., M10×1) and are commonly made from galvanized steel, stainless steel, or zinc-plated materials for corrosion resistance. They connect grease guns to machinery, enabling efficient lubrication of bearings, gears, and hydraulic components.

Standardized Dimensions: DIN 71412 ensures compatibility across European machinery, simplifying replacements and upgrades.
High-Pressure Tolerance: Engineered to withstand up to 10,000 psi, ideal for heavy-duty applications like construction equipment.
Leak-Proof Sealing: Tapered threads and reinforced seating prevent grease leakage, even in high-vibration environments.
Material Versatility: Options include stainless steel for corrosive environments and zinc-plated variants for cost-effective solutions
DIN 71412 grease nipples are widely used in:
Automotive Systems: Lubricate chassis joints, suspension components, and drivetrain parts.
Agricultural Machinery: Ensure smooth operation of harvesters, tractors, and irrigation pumps.
Manufacturing Equipment: Maintain bearings and conveyor systems in production lines
Proper Alignment: Ensure the fitting aligns with the grease gun nozzle to avoid cross-threading.
Regular Cleaning: Use a lint-free cloth to remove debris from the nipple head before lubrication.
Seal Replacement: Replace worn O-rings or washers to maintain pressure integrity.
Lubricant Compatibility: Match grease type (e.g., lithium-based) with the fitting’s material to prevent chemical degradation
