About Spiral hoses

Spiral hoses carry compressed air to moving workstations and pull themselves back once released, so no loop is left lying on the floor for anyone to trip over. Operating pressure across the group is 10 to 16 bar, with an operating temperature range from -40 °C to 100 °C. Some items ship as a complete kit with blow gun and permanently fitted coupling.

What matters when choosing

• Type of connection: combinations range from standard coupling NW 7.2 with nipple NW 7.2 through push-button safety coupling NW 7.4 to steel coupling NW 7.8. Safety couplings vent the hose before it separates and are the better choice on hand-held tools.
• Thread: for permanent fitting the range offers G 1/4 male and G 3/8 male plus taper R 1/8 male, R 1/4 male and R 3/8 male.
• Operating pressure: the range is rated at 10 to 16 bar maximum, and each item additionally states the maximum operating pressure at 23 °C. In warm surroundings that second figure is the one to work with.
• Temperature: minimum operating temperature -40 °C to 0 °C and maximum 50 °C to 100 °C, with a medium temperature of -20 °C to 60 °C quoted for part of the range. For outdoor and cold areas the lower value governs.
• Working length and geometry: maximum working length, number of coils and outer spiral diameter set both reach and recoil force. A wider coil reaches further but sags more.

Typical applications

• Feeding air tools at assembly and inspection stations
• Blow-off and cleaning work with a blow gun in the workshop and on the shop floor
• Moving connections on handling equipment and robots where the hose travels with the axis
• Overhead drops above workbenches so the line stays off the floor
• Vehicle workshops and tyre service, where the working position changes constantly

The group holds 131 items, among them hoses in polyurethane and polyamide as well as fibre reinforced versions for higher pressures. Production is in Italy, Sweden, the USA, Taiwan and China.
