It can seem counterintuitive to have holes in something that needs to be pressurised. Even so, those tiny holes or pin-pricks, actually help keep the hose in good condition and extend its lifespan.
The tiny pin-pricks only puncture the tube's outer cover. So, the gases that gradually build-up between the tube and the cover can escape. This prevents the hose from becoming blistered or bubbled, improving its reliability and life-time.
How is pin-pricking done?
A wheel passes along the hose as it's pulled from the mandrel – pricking the cover in a series of uniform punctures that stop at the reinforced layer.
For hoses ranging from 11.5mm to 85mm Ø OD, our hose pricking equipment guarantees the hose is perforated at the correct tolerance.
Our pin-pricked hose comes in:
- Full coils
- Bespoke cut lengths
- Fully assembled
All pin-pricked hoses arrive with you clearly labelled so you can easily identify them from standard hose.
