MagLock Helmet Adapters for Stilo, Bell, Roux, Arai, Stand 21 & Zamp

MagLock Helmet Adapters — Designed by Harris Race Radios for Stilo, Bell, Roux, Arai, Stand 21 & Zamp

As one of the first specialists in Australasia to adopt the MagLock forced air helmet connection system, Harris Race Radios identified a critical compatibility problem: the standard 1.5" round fitment used by most MagLock systems is not compatible with the proprietary air fittings on several major helmet brands. The result is a poor seal, reduced airflow, and a frustrating installation experience.

To solve this, Harris Race Radios designed and developed our own range of MagLock helmet adapters — precision-engineered to bridge the gap between the MagLock system and the specific air inlet geometry of Stilo, Bell, Roux, Arai, Stand 21, and Zamp helmets. Each adapter also incorporates a 30-degree angle to provide greater flexibility in hose routing direction — reducing strain on the connection and improving fitment in tight cockpit environments.

Why You Need a Helmet-Specific MagLock Adapter

Not all helmet air fittings are created equal. Using a generic 1.5" MagLock connection on an incompatible helmet inlet can result in:

• Air leaks at the connection point — reducing cooling effectiveness
• Difficulty seating and releasing the MagLock under race conditions
• Potential damage to the helmet's air inlet fitting
• Unreliable forced air delivery during critical race moments

Our adapters ensure a secure, airtight connection between your MagLock system and your helmet — so your forced air cooling works exactly as intended, every time.

Frequently Asked Questions

Which helmets are these adapters compatible with?

These adapters are designed for Stilo, Bell, Roux, Arai, Stand 21, and Zamp helmets with forced air inlets. Contact Aaron Harris to confirm compatibility with your specific helmet model.

Why do I need a helmet-specific adapter?

The standard 1.5" round MagLock fitment is not compatible with the proprietary air inlet geometry of many helmet brands. Without the correct adapter, you risk air leaks, poor cooling performance, and potential damage to your helmet's air fitting.

What is the 30-degree angle for?

The 30-degree angled design provides greater flexibility in hose routing direction — particularly useful in tight cockpit environments where a straight connection would create strain on the hose or fitting.

Will this work with my existing MagLock forced air system?

Yes — these adapters are designed to work with standard MagLock forced air systems. Contact us to confirm compatibility with your specific setup.

Is NZ and AU stock available?

Yes — Harris Race Radios holds NZ stock for fast local dispatch and ships directly to Australia.
