- New 5/16″ I.D. gray hoses are a direct replacement for the previous 8mm and 10mm teal hoses. The previous teal hose part numbers remain the same for the new gray hoses.
- Allows 30% more airflow to the tool than previous 8mm offering and 10% more airflow to the tool than previous 10mm offering.
- Previous 8mm & 10mm offering could experience occurrences of off-gassing. This occurs when air bypasses or bursts through an internal hose lining, creating a bubble on the outer skin – a potential bursting safety hazard.
- Reusable fittings provide a safe and consistent connection and allow for easy length customization.
- Made in USA.
