The hose must be rated to at least match the maximum working pressure of the compressor. Most domestic compressors operate at 8–10 bar; workshop compressors at 10–15 bar. The working pressure is different from the burst pressure — a hose rated at 20 bar working pressure has a much higher burst threshold. As a rule, choose a hose rated at least 50% above your compressor's working pressure to allow for pressure spikes.

Rubber is the best all-round choice for workshop use. It handles high pressure, stays flexible in cold temperatures, and has a longer service life than PVC. Polyurethane is lighter and more resistant to abrasion, which makes it a good choice for portable tools and environments where the hose gets dragged across rough surfaces. PVC is the cheapest option but stiffens in cold conditions and has a shorter working life under regular use.

For most air tools (impact wrenches, drills, spray guns), an 8 mm (5/16 inch) internal bore is the standard. For longer runs or higher-volume tools such as large sanders or plasma cutters, 10 mm (3/8 inch) gives less pressure drop. For fixed workshop airline installations with multiple takeoff points, 13 mm (1/2 inch) is common. Match the hose bore to the connections on your tools and the ports on your compressor.

There is no fixed maximum length, but longer hoses cause more pressure drop. A 30-metre run of 8 mm bore hose will deliver noticeably less pressure at the tool end than a 10-metre run at the same compressor setting. If you need a long run, increase the bore rather than the compressor output. Coiled hoses also introduce more restriction than straight hoses of equivalent length.
