Selecting pneumatic tubing doesn\u2019t need to be overly complicated; simply keeping three core principles in mind\u2014suitability for the environment, sealing performance, and service life\u2014is sufficient. If you base all subsequent selection decisions around these key points, you can hardly go wrong.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. <\/b>The material, dimensions, and pressure rating of the hose must be properly matched with the working pressure, conveyed medium, connector type, and installation environment specified in the original design drawings. Do not attempt to make do with unsuitable components, as this significantly increases the risk of failure.<\/li>
  2. The hose must feature uniform wall thickness, a smooth inner surface, and compatible connections; this ensures that compressed air does not leak, minimizes pressure loss, and enables the system to operate stably.<\/li>
  3. Selection should be based on the specific operating environment\u2014for instance, whether corrosive substances are present, if temperatures are high, or if frequent bending is required. Choosing the appropriate material and wall thickness can extend the hose\u2019s service life; by reducing the frequency of replacements, you save both time and money.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The material of a pneumatic hose directly determines its resistance to high temperatures, corrosion, and pressure, as well as the specific environments in which it is suitable for use. Hoses made from different materials vary significantly; therefore, users should make their selection based on their specific operating conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    PU Hose<\/p>

    (Polyurethane)<\/p><\/td>

    		This is one of the most commonly used types; it offers exceptional flexibility\u2014being lightweight and easy to bend\u2014while also featuring excellent abrasion resistance and anti-aging properties. Its smooth inner wall ensures unimpeded airflow, and it provides reliable sealing at a relatively affordable price point.<\/td>It is suitable for most standard industrial pneumatic systems\u2014such as machine tools, assembly lines, pneumatic manipulators, and small cylinders\u2014and is an excellent choice, particularly for applications involving frequent bending or movement.<\/td>\u2460 Do not use in high-temperature environments exceeding 60\u00b0C or in highly corrosive environments; \u2461 Keep away from sharp objects to avoid scratching the tube walls; \u2462 For standard pressure applications (0.1\u20131.0 MPa), use the regular model; for high-pressure scenarios, be sure to select the thickened version.<\/td><\/tr>

    Nylon Hose<\/p>

    (PA Tube)<\/p><\/td>

    		It possesses sufficient hardness, is resistant to both abrasion and oil, and offers good toughness\u2014making it resistant to breakage. Its high-temperature resistance is slightly superior to that of PU tubing (capable of withstanding temperatures up to approximately 120\u00b0C), and it also exhibits strong compressive strength; however, its price is slightly higher than that of PU tubing.<\/td>Suitable for lubricated compressed air systems and medium-to-high pressure (1.0\u20131.6 MPa) pneumatic equipment\u2014such as the pneumatic circuits of heavy machinery or equipment connections in high-temperature environments\u2014it is particularly well-suited for fixed piping or applications where minimal bending is required.<\/td>\u2460 Its flexibility is slightly inferior to that of PU tubing; avoid frequent, forceful bending, as this can lead to premature aging and cracking. \u2461 When pairing it with compression fittings or quick-connect fittings, ensure that the dimensions are precisely matched. \u2462 Do not expose it to direct sunlight for prolonged periods, as this will accelerate the aging process.<\/td><\/tr>

    PU<\/p>

    Braided Hose<\/p><\/td>

    It possesses excellent flexibility and chemical properties, as well as good shock resistance; it is lightweight, exhibits minimal pressure loss, and maintains consistent hardness.<\/p>

    Its working pressure is 1.8 times that of single-layer PU tubing, and its service life exceeds that of single-layer PU tubing by more than two times.<\/p>

    It is non-toxic and odorless.<\/p><\/td>

    Industrial robots, pneumatic tools, pneumatic equipment for assembly plants, and pressurized transport pipelines.<\/p>

    Conveyance of water and other fluids.<\/p>

    Vehicle maintenance and residential painting.<\/p><\/td>

    		\u2460 It is somewhat heavy, making installation less convenient; furthermore, with prolonged use, it is prone to aging and delamination. \u2461 When pairing it with clamp-style pipe fittings, pay particular attention to verifying the inner diameter of the hose. \u2462 Avoid contact with highly corrosive substances, as they will corrode and damage the hose walls. 4. Do not use in environments exceeding 80\u00b0C.<\/td><\/tr>
    PTFE Tube (Polytetrafluoroethylene Tube)<\/td>It boasts exceptional corrosion resistance\u2014impervious to strong acids, strong bases, and organic solvents\u2014and exhibits impressive high-temperature tolerance (withstanding temperatures exceeding 200\u00b0C). Its smooth inner walls ensure unimpeded airflow, and it offers excellent sealing performance; however, it lacks flexibility and comes at a relatively high price.<\/td>Suitable for specialized, harsh environments\u2014such as the chemical, medical, and food industries\u2014and for pneumatic systems involving corrosive media or high temperatures; intended exclusively for fixed piping installations and cannot be bent.<\/td>\u2460 Poor flexibility: strictly avoid forceful bending, as it is prone to breakage; \u2461 When paired with ferrule-type tube fittings, dimensional tolerances are quite strict; \u2462 High cost: do not select this option unless the application involves special circumstances.<\/td><\/tr>
    PE Pneumatic Hose<\/td>

    Constructed from high-quality PE material, offering superior resistance to acids and alkalis compared to standard PE tubing.<\/p>

    The inner and outer surfaces of the tube are smooth, facilitating a smoother flow of liquids.<\/p>

    The tubing is semi-transparent, allowing the fluid flowing inside to be visible.<\/p>

    Temperature Range: 0\u00b0C to +55\u00b0C.<\/p>

    Suitable for conveying acidic and alkaline substances, including lacquer thinner, dilute acids, toluene, electroplating solutions, and other chemicals.<\/p><\/td>

    		Suitable for most standard industrial pneumatic systems\u2014such as machine tools, assembly lines, pneumatic manipulators, and small cylinders\u2014particularly in applications requiring frequent bending.<\/td>Please exercise caution when using this product in applications involving media temperatures exceeding 60\u00b0C, or fluids containing corrosive components (such as strong acids, strong bases, highly polar solvents, etc.), as there is a risk of hose rupture. Similarly, exercise caution in operating environments where the ambient temperature exceeds 60\u00b0C, or where chemical gases are present; such conditions may cause the hose to soften\u2014leading to a significant reduction in pressure resistance\u2014or result in rapid aging and cracking due to chemical corrosion. Do not store the product in damp environments or for extended periods (exceeding 12 months), as moisture-induced hydrolysis may occur, potentially leading to hose failure.<\/td><\/tr><\/tbody><\/table>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Addendum: For standard operating conditions, opt for PU or PE tubing\u2014they are lightweight, flexible, and durable. For high-pressure applications involving oil, choose Nylon; it is robust and offers worry-free pressure resistance. For high-pressure, high-flow scenarios, select braided tubing\u2014it is cost-effective, practical, and highly versatile. Finally, for corrosive or high-temperature environments, choose PTFE; it is the ideal solution for handling even the most demanding special conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Matching dimensions is the most common pitfall when selecting hoses; many people confuse \u201couter diameter,\u201d \u201cinner diameter,\u201d and \u201cnominal bore.\u201d Consequently, the hose they purchase fails to fit the connectors\u2014making assembly impossible and resulting in air leaks. In reality, it is quite simple; let\u2019s walk through it step-by-step so you can easily avoid this common mistake.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    When we purchase pneumatic tubing, the specifications \u03c66, \u03c68, and \u03c610 refer to the *outer diameter* of the hose (commonly known as the \u201cnominal size\u201d)\u2014not the inner diameter, nor the \u201cnominal bore\u201d as defined in piping standards.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Let me give you an example to clarify: for an 8mm PU tube (designated as \u03c68), the outer diameter is 8mm, while the inner diameter is approximately 6mm; the corresponding nominal diameter is likely DN6. If you mistakenly treat the nominal diameter as the outer diameter when making a purchase, the hose certainly won\u2019t match the fittings\u2014meaning you won\u2019t be able to install it, and you\u2019ll end up wasting money.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
