Brake & Clutch Dry Break Quick Release Couplings

Our Brake & Clutch Dry Break Quick Release Couplings provide a fast, clean and secure way to disconnect AN3 hydraulic lines in motorsport applications. Designed primarily for motorcycle brake systems and automotive clutch systems, the double shut-off design automatically closes both sides of the coupling when disconnected, helping to minimise brake or clutch fluid loss and air ingress.

Why Choose Our Brake & Clutch Dry Break Couplings?

Ideal for Motorcycle Brake Systems

Designed for AN3 motorcycle and race bike brake lines, allowing hydraulic connections to be separated quickly when removing or changing brake components during servicing, setup changes or race preparation.
Suitable for Automotive Clutch Systems

Also ideal for motorsport clutch lines, providing a convenient disconnect point where the hydraulic line needs to be separated during gearbox removal, clutch servicing or component changes.
Double Shut-Off Dry Break Design

Both halves of the coupling feature an internal shut-off system which automatically closes when disconnected, helping to minimise hydraulic fluid loss and air ingress while the line is separated.
Ultra-Lightweight 6Al-4V Titanium Construction

Manufactured from 6Al-4V titanium for high strength with minimal weight. The complete coupling weighs just 25g, making it particularly suited to weight-conscious motorcycle and motorsport applications.
2,900 PSI Maximum Operating Pressure

Rated to a maximum operating pressure of 2,900 PSI (200 bar) for demanding brake and clutch hydraulic systems.
Compatible with DOT Brake Fluids

EPDM internal seals provide compatibility with DOT 3, DOT 4 and DOT 5.1 brake fluids for use in compatible brake and clutch hydraulic systems. Not suitable for use with Castrol SRF brake fluid.
Supplied as a Complete Coupling

Supplied as a complete set with both mating halves of the dry break coupling, ready to integrate into a compatible AN3 hydraulic line.

What Is a Brake & Clutch Dry Break Coupling?

A dry break coupling is a quick-release hydraulic connector designed to automatically seal both sides of a fluid line when disconnected. The double shut-off system helps minimise fluid escaping from the line while also reducing the amount of air entering the hydraulic system.

For motorcycle brake and automotive clutch systems, this provides a convenient way to separate sections of the hydraulic circuit where components need to be removed, serviced or changed regularly.

Designed for Motorcycle & Motorsport Maintenance

Whether you're removing braking components from a race motorcycle or disconnecting a clutch hydraulic line during gearbox removal, the AN3 Brake & Clutch Dry Break Quick Release Coupling provides a compact, ultra-lightweight and reusable connection designed to make servicing quicker and cleaner.

For motorsport use only. Not approved for road use.

Frequently Asked Questions

What is a brake and clutch dry break coupling?
A brake and clutch dry break coupling is a quick-release hydraulic connector that allows an AN3 fluid line to be separated quickly and cleanly. Internal shut-off valves automatically close both sides when disconnected, helping to minimise brake or clutch fluid loss and reduce air entering the hydraulic system.
How does a dry break coupling work?
When the two halves of the dry break coupling are connected, the internal valves open to allow hydraulic fluid to flow through the coupling. When disconnected, the double shut-off system automatically closes both sides, helping to retain fluid within the separated sections of the hydraulic system.
What are AN3 dry break couplings used for?
AN3 dry break couplings are designed for motorsport brake and clutch systems. They are particularly useful for motorcycle and race bike brake lines where braking components may need to be removed or changed regularly, and for automotive clutch lines where the hydraulic connection may need to be separated during gearbox removal or clutch servicing.
Are these dry break couplings suitable for motorcycle brakes?
Yes. These AN3 couplings are particularly suited to motorcycle and race bike brake systems, providing a compact quick-release connection that allows sections of the hydraulic system to be separated while helping to minimise fluid loss and air ingress.
Can I use these dry break couplings on a clutch line?
Yes. The AN3 coupling is suitable for compatible hydraulic clutch systems and can provide a convenient disconnect point for applications such as gearbox removal, clutch servicing and motorsport component changes.
Which brake fluids are compatible?
The coupling uses EPDM seals and is compatible with DOT 3, DOT 4 and DOT 5.1 brake fluids. It is not specified for DOT 5 silicone brake fluid and must not be used with Castrol SRF brake fluid.
What is the maximum operating pressure?
The AN3 Brake & Clutch Dry Break Quick Release Coupling has a maximum operating pressure of 2,900 PSI (200 bar), making it suitable for demanding motorsport brake and clutch hydraulic applications.
What is the operating temperature range?
The coupling has an operating temperature range of -20°C to 150°C (-4°F to 302°F).
What material is the AN3 dry break coupling made from?
The coupling is manufactured from 6Al-4V titanium, providing high strength, corrosion resistance and ultra-low weight. The complete coupling weighs just 25g.
Are both halves of the dry break coupling included?
Yes. The coupling is supplied as a complete set with both mating halves, ready to integrate into a compatible AN3 brake or clutch hydraulic line.
Will I need to bleed the brakes or clutch after disconnecting the coupling?
The double shut-off design helps to minimise fluid loss and the amount of air entering the hydraulic system when disconnected. However, the hydraulic system should always be checked after reconnection and bled if necessary before use.
Are these dry break couplings suitable for road use?
No. These AN3 Brake & Clutch Dry Break Quick Release Couplings are intended for motorsport use only and are not approved for road use.
How should I maintain a brake or clutch dry break coupling?
Regularly inspect the coupling and sealing surfaces for damage, wear or contamination and keep the connection clean when disconnected. Any cleaning or lubrication products used should be compatible with the coupling's EPDM seals and the brake or clutch fluid in the system.
