High Pressure Dn2 & Dn4 Microbore Hose, Fittings & Assemblies

High-pressure DN2 and DN4 microbore hoses, fittings, and assemblies are specialized components designed for applications requiring high pressure and precision fluid control in compact spaces. Here are detailed insights into these components:

High Pressure DN2 & DN4 Microbore Hoses

DN2 and DN4:

DN2: Refers to a hose with an internal diameter of 2 mm.
DN4: Refers to a hose with an internal diameter of 4 mm.

Characteristics:

High-Pressure Capability: These microbore hoses are designed to handle extremely high pressures, often up to 700 bar (10,000 psi) or higher, depending on the specific application and manufacturer.

Small Diameter: The small internal diameter allows for precise control and measurement of fluid flow, making them ideal for applications requiring high accuracy.

Flexibility: Despite their high-pressure rating, these hoses are typically very flexible, which makes them suitable for use in tight spaces or applications with complex routing requirements.

Fittings for High-Pressure Microbore Hoses

Types:

Threaded Fittings: Common types include BSP, NPT, and metric threads, which ensure secure and leak-free connections.

Quick Connect Couplings: These allow for easy and rapid connection and disconnection of hoses without tools, improving efficiency in operations.

Swivel Fittings: Enable hoses to rotate, preventing twisting and kinking, thus extending the hose life and maintaining fluid flow integrity.

Materials:

Typically made from stainless steel, brass, or other high-strength alloys to withstand high pressures and provide corrosion resistance.

Sealing Mechanisms:

O-ring seals, tapered threads, or metal-to-metal seals ensure leak-free connections even under extreme pressures.

Assemblies of High-Pressure Microbore Hoses

Custom Assemblies:

Pre-Assembled Hoses: Custom lengths of hose with pre-attached fittings, tested for pressure integrity and ready for immediate use.

Multi-Hose Bundles: Multiple hoses bundled together to simplify installation and reduce clutter in complex systems.

Protective Sleeves: Assemblies may include protective sleeves or coverings to shield hoses from abrasion, heat, or other environmental hazards.

Applications:

Hydraulic Systems: Used in hydraulic tools, jacks, and presses where precise control of high-pressure fluid is required.

Test and Measurement: Ideal for high-pressure testing equipment and instrumentation where accurate pressure readings are critical.

Medical and Laboratory Equipment: Suitable for use in devices requiring high pressure and small fluid volumes, such as chromatography and other analytical equipment.

Advantages of DN2 & DN4 Microbore Hoses

Precision: A small internal diameter allows for precise fluid control and measurement.

Compactness: Suitable for use in confined spaces due to their small size and flexibility.

High Pressure Handling: Capable of withstanding very high pressures, making them suitable for demanding applications.
