The Drass D-ONE Diving Helmet Annual Repair Kit provides the replacement components required for scheduled annual maintenance and servicing of the Drass D-ONE commercial diving helmet.
The kit brings together the seals, O-rings, gaskets, springs, valves, regulator components and other service parts required for the annual repair procedure, allowing D-ONE operators and authorised service personnel to maintain critical helmet components using the specified replacement parts.

What is a D-ONE Annual Repair Kit?
Commercial diving helmets contain numerous seals, valves and mechanical components that are subject to wear during normal operation.

The kit contains components for several areas of the helmet, including:
- Face port assembly
- Oral-nasal system
- Exhaust system
- Pod assembly
- Regulator
- Side block
- Defogger system
- Emergency gas system
- Helmet locking and handle assemblies
Maintenance and component replacement should be carried out in accordance with the applicable Drass D-ONE service and maintenance procedures.

Why Scheduled Diving Helmet Maintenance Matters
A commercial diving helmet is life-support equipment, so scheduled inspection and maintenance are fundamental to maintaining its intended operating condition.
Components such as O-rings, diaphragms, valve components, gaskets and springs can be affected by repeated operation, environmental exposure and normal wear.
Using the specified replacement components during scheduled servicing helps maintain the helmet’s original configuration and provides traceability of the parts installed during maintenance.
