In industrial production, a hose may seem like just a small connecting component, yet it plays a critical role in conveying media, transmitting pressure, and ensuring the safe operation of equipment. Faced with a wide range of product categories—including nylon resin high-pressure hoses, PU polyurethane steel wire hoses, and TPV rubber hoses—how do you make the right choice based on your actual working conditions? This article provides a systematic overview from three dimensions: material characteristics, application scenarios, and key selection criteria.

I. Comparison of Three Mainstream Hose Material Characteristics

Nylon Resin Hoses

Nylon resin hoses are renowned for their outstanding pressure
resistance and chemical stability. With a smooth inner wall and low fluid resistance, they maintain excellent dimensional stability even under high-pressure conditions. Nylon resin high-pressure hoses are widely used in hydraulic systems, pneumatic tools, and automated equipment. Meanwhile, nylon resin test hoses, with their precise pressure measurement capability and good flexibility, are an ideal choice for pressure gauge connections and pressure detection applications.

PU Polyurethane Hoses

PU polyurethane material combines the flexibility of rubber with the wear resistance of plastic, making it one of the most widely used materials in the hose industry. PU polyurethane steel wire duct hoses, supported by a steel wire skeleton, offer excellent compression and tensile resistance, making them suitable for industrial ventilation, dust extraction, woodworking machinery, and similar applications. PU polyurethane reinforced hoses maintain good flexibility while enhancing the tube body's compression resistance through a ribbed structure, and are commonly used in vacuum conveying and granular material handling.

TPV Rubber Hoses

TPV (Thermoplastic Vulcanizate) hoses combine the elasticity of rubber with the processing convenience of thermoplastic materials. They feature excellent weather resistance, oil resistance, and anti-aging performance, performing exceptionally well even under repeated bending and extreme temperature conditions. They are ideal for applications with high durability requirements, such as automotive manufacturing, construction machinery, and automated production lines.

II. Selection Recommendations for Different Working Conditions

High-pressure hydraulic systems — Nylon resin high-pressure hoses are recommended. Their core advantages include high pressure resistance, dimensional stability, and excellent chemical compatibility, enabling long-term stable operation under high-pressure environments.
Pressure detection and instrument connections — Nylon resin test hoses are recommended. With good flexibility, precise pressure measurement, and easy installation, they are the ideal choice for pressure gauge connections and pressure testing applications.
Industrial ventilation and dust extraction — PU polyurethane steel wire duct hoses are recommended. They offer compression and tensile resistance, wear resistance, and a smooth inner wall, effectively ensuring ventilation and conveying efficiency.
Vacuum conveying and material handling — PU polyurethane reinforced hoses are recommended. With strong flexibility, rib-reinforced structure, and lightweight design, they are well suited for frequent material handling operations.
Ultra-high pressure water jet cleaning — Ultra-high pressure cleaning hoses are recommended. Featuring ultra-high pressure resistance, pulse resistance, and reliable safety, they meet the demands of the most rigorous cleaning conditions.
Repeated bending and extreme temperature environments — TPV rubber hoses are recommended. With excellent weather resistance, oil resistance, superior elasticity, and long service life, they adapt well to complex and variable working environments.

III. Key Parameters to Focus on During Selection

In actual procurement, in addition to material selection, the following parameters should not be overlooked:

Working pressure and burst pressure: Ensure that the hose's rated working pressure exceeds the actual operating pressure, with sufficient safety margin.
Media compatibility: Confirm that there is no chemical reaction or swelling between the hose material and the liquid, gas, or granular material being conveyed.
Temperature range: Different materials have significantly different temperature tolerance ranges; selection should be based on the maximum and minimum temperatures of the working environment.
Bend radius: When installation space is limited, pay close attention to the hose's minimum bend radius to avoid damage to the tube body caused by excessive bending.
Fitting compatibility: The connection method between the hose and fittings directly affects sealing performance and service life. It is recommended to choose fitting solutions provided by the hose manufacturer.
