In modern hydraulic systems, real-time and accurate pressure monitoring is essential for ensuring safe equipment operation, optimizing performance, and preventing failures. The nylon resin pressure measurement hose, as a core component for pressure measurement and signal transmission, has become an ideal choice for hydraulic system pressure monitoring, thanks to its excellent pressure-bearing capacity, reliable sealing performance, and convenient connection methods.

What Is a Nylon Resin Pressure Measurement Hose?

A nylon resin pressure measurement hose is a high-pressure hose product specifically designed for pressure measurement in hydraulic systems. It features a nylon extruded inner core, a high-strength fiber braided or steel wire wound reinforcement layer, and is equipped with specialized pressure test connectors at both ends. These connectors enable quick connection to pressure gauges, pressure sensors, pressure switches, and other pressure measuring devices, allowing real-time monitoring of hydraulic system operating pressures.

Pressure measurement hoses are typically used at hydraulic system pressure test points, bleed points, or oil filling points, serving as essential tools for system condition monitoring and fault diagnosis.

Key Features of Nylon Resin Pressure Measurement Hoses

1. Excellent High-Pressure Capacity

Nylon resin pressure measurement hoses offer maximum working pressures up to 70MPa (depending on specifications), with burst pressures 2.5 to 3 times the working pressure, providing a high safety margin that meets the pressure measurement requirements of various medium- and high-pressure hydraulic systems.

2. Wide Temperature Range

With an operating temperature range of -40°C to +120°C, these hoses maintain stable performance in extreme conditions, from severe cold to high heat, adapting to diverse geographic and seasonal environments.

3. Good Media Compatibility

The inner nylon layer provides excellent resistance to oil and chemical media, making it compatible with mineral oils, synthetic hydraulic fluids, water-glycol mixtures, emulsions, and various other hydraulic media, ensuring broad applicability.

4. Accurate Pressure Transmission

The hose features a favorable volumetric elastic modulus, exhibiting minimal volume expansion under pressure changes. This allows for true and accurate transmission of system pressure to measuring devices, ensuring measurement precision.

5. Lightweight, Flexible, and Easy to Route

Compared with metal pressure test tubes, nylon resin pressure measurement hoses are lighter in weight and more flexible, enabling easy routing in confined spaces. This reduces installation difficulty and minimizes the impact of line vibration on pressure measuring components.

6. Multiple Connector Options

Available with various pressure test connector specifications, including M16×2, M20×1.5, G1/4, and other common thread interfaces, as well as quick couplings and adapters, compatible with pressure gauges and sensors of different brands and models.

Selection Guidelines

When selecting a nylon resin pressure measurement hose, customers are advised to pay attention to the following factors:

Working Pressure: Choose an appropriate pressure rating based on the maximum working pressure of the hydraulic system, ensuring a sufficient safety margin.

Operating Temperature: Verify that the system operating temperature falls within the hose's allowable temperature range.

Media Type: Ensure the hose material is compatible with the hydraulic media used in the system.

Connector Specification: Confirm that the pressure hose connector threads match those of the pressure gauge or sensor.

Installation Space: Select an appropriate outer diameter and length based on the bending radius requirements at the installation location.

Installation and Usage Recommendations
Avoid excessive bending during installation; the bending radius should not be less than the product's specified minimum bend radius

Use appropriate torque when tightening connectors—avoid over-tightening or under-tightening

Regularly inspect the hose appearance for signs of wear, cracks, or aging

Release system pressure before disconnecting the hose after pressure measurement is completed

Replace the pressure measurement hose periodically based on usage frequency and operating conditions to ensure measurement reliability
