Pneumatic Tubing Guide for Chemical Resistance

Selecting the right pneumatic tubing requires more than matching tube size and pressure requirements. When tubing is exposed to chemicals, oils, solvents, fuels, or other fluids, material compatibility is critical to maintaining system performance and service life. Different tubing materials offer varying levels of resistance to specific chemicals and operating conditions. Polyconn’s Tubing Chemical Resistance Chart provides a quick reference for evaluating the compatibility of common tubing materials with a range of chemicals and substances. Use this chart to help narrow your tubing options, then consider other application requirements such as temperature, pressure, flexibility, and exposure conditions before making a final selection.

How to Use the Chemical Resistance Chart

The chemical resistance chart compares the chemical resistance of common plastic tubing materials, such as polyurethane, polyethylene, PVC, nylon, and Kynar, against various chemical substances. This chart should be used before specifying tubing for applications involving chemical exposure to ensure the proper material is being selected. To properly use the chemical resistance chart, follow these steps:

• Step1: Identify the chemical or fluid the tubing will contact.
• Step 2: Compare compatible tubing materials on the chart.
• Step 3: Verify application requirements such as temperature, pressure, concentration, exposure time, and operating conditions before making a final selection.

Chemical Compatibility is Only One Part of the Tubing Selection

Selecting the proper tube needs to consider additional factors and tubing technical information to ensure the right material is used for the pneumatic application. These additional factors are critical for safety, longevity, and operating conditions with your tubing requirements. In addition to chemical resistance, tubing selection should account for:

• Operating and burst pressure
• Temperature range
• Tubing size
• Flexibility
• Permeation
• Environmental conditions
• Regulatory or application requirements

Chemical-Resistant Tubing for Multiple Industries

Chemical-resistant tubing plays an important role in many harsh conditions across multiple industries. By determining the right chemical resistance of the different materials, the right tubing can be selected for your operations. Industries that benefit from careful tubing material selection include:

• Chemical Processing
• Food & Beverage
• Medical and Laboratory
• Automotive
• Plastics and Manufacturing
• Industrial Automation
• Waste and Wastewater
• Agriculture
