Engine Oil Cooler Hose Assembly

The Engine Oil Cooler Hose Assembly is a complete hose system used to transport engine oil to and from the oil cooler. Comprised of oil- and temperature-resistant hoses, clamps, fittings, and seals, it directly replaces original equipment parts, ensuring reliable oil circulation between the cooler and the engine, preventing overheating and ensuring effective lubrication.

Product Features:
Designed to withstand the high oil temperatures and operating pressures found within the engine oil circulation system, it utilizes high-quality rubber, synthetic materials, or braided steel reinforcement to ensure it resists bursting and deformation under extreme operating conditions.
The hose's inner layer offers excellent oil resistance, resisting chemical attack from hot oil, lubricants, and additives, preventing material degradation and leaks.

It includes a precisely formed hose, durable rigid hose section, original equipment specification connectors, seals, and positioning brackets, ensuring a perfect fit and immediate installation at the engine and cooler interfaces, reducing installation time and the risk of leaks.

The rigid metal hose section typically features a surface treatment such as galvanizing for excellent corrosion resistance, resisting environmental moisture, salt, and dirt. Ensure that the oil circulates quickly and smoothly between the engine and the oil cooler to achieve efficient cooling effect and maintain the engine oil temperature within the optimal range

News and Information

Engine Oil Cooler Hose Assembly Industry knowledge

The?Engine Oil Cooler Hose Assembly?is a critical component of the engine lubrication system's circulation loop. This assembly is responsible for establishing a sealed oil passage between the engine and the oil cooler, facilitating the transfer of hot oil and the return of cooled oil. Its core function is to ensure oil circulates at specified pressures and flow rates, maintaining oil temperature within the engine's required operating range through heat exchange.

?

Technical Characteristics?

1. Material and Structural Characteristics

  • Resistance Properties:?The component materials possess chemical stability resistant to high temperatures, oil, and hydraulic oil additives. Common structures include an inner liner, a reinforcement layer (such as fiber or steel wire braid), and an outer cover.

  • Pressure and Temperature Ranges:?The typical operating temperature range is -40°C to above +150°C. The operating pressure is designed according to engine system requirements and can withstand system pulse pressures.


2. Engineering Compatibility Characteristics

  • Dimensions and Interfaces:?The assembly's length, bend radius, fitting types (e.g., flange, thread), and seal specifications are consistent with the original vehicle components.

  • Integrated Attachments:?The assembly integrates mounting brackets, abrasion sleeves, and other attachments to ensure a fixed routing path and clearance within the engine compartment.


3. Surface Treatment and Fluid Performance

  • Corrosion Protection:?Metal fittings and rigid tube sections undergo surface treatment processes such as electroplating to enhance resistance to environmental corrosion.

  • Flow Efficiency:?The inner wall of the tubing is smooth, and the design avoids flow dead zones to reduce flow resistance and promote heat exchange efficiency.


Structure and Function Correspondence Table

Component Primary Function Technical Manifestation
Multi-layer Composite Hose Convey fluid, withstand pressure and temperature Material oil & temperature resistance data; Burst pressure value
Metal Rigid Tube & Fittings Provide rigid connection and interface Material specification (e.g., stainless steel); Interface standard (e.g., DIN/SAE)
Sealing Elements Ensure sealing at connection points Material (e.g., FKM); Operating temperature range
Positioning Brackets Secure the assembly, manage vibration and displacement Bracket material (e.g., steel, aluminum); Mounting point design

Working Principle:?When the engine is running, the oil pump delivers hot oil. This oil is transported via the supply line of the?Engine Oil Cooler Hose Assembly?to the oil cooler. Within the cooler, the oil's heat is dissipated through exchange with a cooling medium (air or coolant). The cooled oil then returns to the engine oil pan or main gallery via the assembly's return line, completing the cooling cycle.
