What is the difference between straight tubes and recoil hoses?

Straight tubes (EU-series) come in rolls and are cut to length for permanent installations. Recoil hoses (EUC-series) are pre-coiled and self-retracting, ideal for portable tools and workstations where the hose needs to retract when not in use. Recoils with connectors (EUC-C) include factory-fitted swivel fittings for instant connection.

Can I use PU tubes near welding operations?

Standard PU tubes will melt or burn from welding sparks. Use the SPAC AU-series anti-spark PU tubes which have a fire-resistant outer layer specifically designed for welding environments. The outer layer resists spark and slag damage while the inner TPU layer maintains pneumatic performance.

What colours are available and why does colour matter?

SPAC PU tubes are available in blue, yellow, black, green, red, transparent, clear blue, clear red, and milky white. Colour-coding your pneumatic circuits (e.g., blue for supply, red for exhaust, yellow for signal) makes maintenance and troubleshooting significantly faster. Transparent and milky white tubes are preferred in food and pharmaceutical environments for visual cleanliness.
