Air Tools & Compressor Accessories
Air hose and coupling sets
Made-up hose assemblies with claw or screw couplings, whipchecks and safety clips, in the bores and pressure ratings the tools require. The part of an air installation that most often loses the pressure the compressor produced.
Features
- Hose bore, not length alone, governs pressure loss — undersizing by one size can cost a bar at the tool over a 30 m run.
- Assemblies are rated to a burst pressure several times working pressure, and a 7 bar hose must never be used on a 14 or 21 bar drilling line.
- Claw couplings are fast and tolerant of grit; screw couplings hold better at high pressure and are standard on drilling air.
- Every coupling in a run needs a retaining clip fitted and a whipcheck across the joint, and both are supplied as part of the assembly.
- Swaged-end assemblies outlast site-fitted worm-drive clips by a wide margin on percussive tools.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Hose bore | 13 / 19 / 25 / 32 | mm | The dominant controllable pressure loss. |
| Assembly length | 10 / 20 / 30 | m | Longer runs need a larger bore. |
| Maximum working pressure | 10 / 14 / 21 | bar | Must match or exceed the compressor pressure class; a 10 bar assembly must not go on a 14 or 21 bar line. |
| Coupling type | claw / screw | Mismatches across a fleet waste hours. | |
| End fitting | swaged / clamped | Swaged ends last far longer on percussive duty. |
