Applicable for compressed air, and general industry water. Consult SMC if using for other kind of fluid. Surge pressure must be under the max operating pressure. If exceeding that value, fitting may be damaged and tubing may burst.

Polyurethane tubing is fast becoming the ideal choice for pneumatic applications. It combines the elasticity of rubber with the chemical resistance normally reserved for plastics. Polyurethane can be put into two classifications, ester based and ether based. SMC offers both. Ether-based polyurethane is the preferred tubing material for general pneumatic applications due to its immunity to hydrolysis and its higher resistance to fungus and microorganism attacks. The ester-based polyurethane is a stronger compound but tends to hydrolyze with moisture. This hydrolysis process will degrade the material over time.

SMC's primary line of Polyurethane tubing is ether based, made from the highest quality compound available to ensure the longest tubing life.
