SAE 100R12 Hose Specifications

Engineered for High-Pressure Impulse Applications, Kingdaflex SAE 100 R12 hydraulic hose is the industry standard for heavy-duty hydrostatic drives. Unlike standard braided hoses, our R12 series features 4 layers of spiralled high-tensile steel wire, providing superior resistance to pressure spikes and flex fatigue.

Impulse Life: Tested to 500,000 cycles (exceeds standard SAE requirements).
Pressure Rating: Handles up to 4,000 PSI (280 Bar) constant working pressure.
Fluid Compatibility: Ideal for petroleum and water-based hydraulic fluids, diesel, and lubricating oils.

SAE J517 100R12 Hose Construction

Inner Lining: Oil-resistant synthetic rubber (Nitrile/NBR). Compatible with hydraulic fluids.

Reinforcement Layer: Four alternating layers of spiraled high-tensile steel wire. This spiral design eliminates the “crossing points” of braided wire, significantly reducing internal friction and heat generation under high impulse loads.

Cover: MSHA-approved abrasion, ozone, and weather-resistant synthetic rubber (Neoprene/CR). Protects against UV radiation and harsh outdoor mining environments.

Applications of SAE 100R12 Hydraulic Hose

The SAE 100 R12 hose is specifically designed for systems subjected to surges, vibration, and high pressure:

Construction: Boom and arm circuits on Excavators (e.g., CAT, Komatsu), Bulldozers, and Mobile Cranes.
Mining: Hydraulic roof supports, rock drills, and tunnel boring machines.
Industrial: Injection molding presses and heavy metal-forming equipment requiring constant high pressure.
Agriculture: High-horsepower tractors and harvester hydrostatic drives.

OEM & Customization Capabilities

We understand that distributors and equipment manufacturers need more than just standard hoses. Kingdaflex offers comprehensive customization services to fit your brand and operational requirements:

Private Label Branding: We can print your company logo, part numbers, and specifications directly on the hose layline using durable, oil-resistant ink or embossed printing. Build your own brand visibility with our manufacturing power.
Custom Lengths & Packaging: Whether you need continuous reels (e.g., 50m/100m) or specific cut-to-length pieces for assembly lines, we accommodate your packaging needs to minimize waste.
Complete Hose Assemblies: Save time and labor costs by ordering ready-to-install assemblies. We provide precision crimping services with matched JIC, BSP, ORFS, or Metric fittings (Zinc Plated or Stainless Steel), ensuring a leak-free connection.

Quality Control & Testing Standards

For high-pressure applications like SAE 100 R12, failure is not an option. Our quality control process exceeds international standards:

Impulse Testing: Our R12 hoses are tested to withstand 500,000 impulse cycles, ensuring reliability under severe pressure spikes and vibration.
100% Proof Pressure Test: Every single batch undergoes a proof pressure test at 2x the working pressure before shipment to detect any potential defects.
Documentation: We provide full Mill Test Certificates (MTC), pressure test reports, and material data sheets with every shipment, giving you full traceability and peace of mind.
