About Pipes and coils

Tubing and coil stock form the fixed distribution level between the compressor and the consumer, with connectors only at the ends. Outside diameters run from 4 to 54 mm and permitted working pressures from 6 to 38 bar, reaching down to -0.95 bar under vacuum. Delivery is either on coils or as straight lengths.

What matters when choosing

• Material comes first. Hard PA 12 to DIN 73378 suits control and machine lines, LLDPE and LDPE are supplied as coil stock, and surface-coated aluminium is used for fixed distribution piping.
• Tube outside diameter from 4 to 54 mm has to match the push-in connector. The speedfit and sharkbite series are dimensioned for it.
• Maximum working pressure lies between 6 and 38 bar depending on material and wall thickness. Use the figure of the actual tube rather than the top value of the group.
• Operating temperature reaches down to -60 °C on the cold-rated versions and up to 65 °C or 100 °C at the upper end.
• Delivery form and installation belong together. Coil length, tube length and the minimum bending radius decide how many bends and connectors a run needs.

Typical applications

• Compressed air ring mains in workshops and production halls.
• Machine and cylinder plumbing with PA 12.
• Cold water and drinking water lines in LLDPE or LDPE.
• Drop lines to service units and take-off points.
• Vacuum lines down to -0.95 bar.

LLDPE and LDPE tubing carries approvals to DVGW worksheet W270, KTW, NSF and WRAS and is suitable for cold water with a chlorine content of up to 4 ppm. Aluminium tubing is corrosion-resistant and electrically insulating, and the 46 articles in this group come from Germany, the United Kingdom, Italy and Turkey.
