Festo Plastic Tube Blue Polyurethane 4 mm 500 m PUN Series, 558257

This plastic tube is a flexible pneumatic conduit designed for compressed-air distribution in automated and industrial installations. Made from polyurethane, it offers adaptable routing in confined assemblies while operating across a broad temperature range. The product is supplied on a long-length reel suitable for extended runs and continuous use in production environments.

• Withstands maximum operating pressure of 0.6MPa enabling robust pneumatic circuits
• Rated for temperatures from -35 to 60°C for varied environmental conditions
• Constructed from polyurethane providing good flexibility and abrasion resistance
• Supplied in a 500m length reducing reel changes and downtime
• Available in blue for clear circuit identification and visual routing

• Suitable for pneumatic control lines in factory automation
• Used with valve islands and manifold assemblies for signal delivery
• Ideal for long-run air distribution on production floors
• Can be used for compressed-air tools and pick-and-place equipment

The internal bore is 2.6mm, which yields low to moderate flow rates appropriate for control and pilot air lines rather than high-volume supply mains.

Polyurethane construction maintains elasticity and resists kinking under cyclical bending, extending service life in dynamic installations.

The blue exterior permits quick visual distinction of circuit types during inspection and servicing operations.

Store on a clean, dry reel rack away from direct heat sources and sharp edges to avoid deformation and surface damage.
