Brake & Clutch Dry Break Quick Release Couplings

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

Why Choose Our Brake & Clutch Dry Break Couplings?

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.
Quick-Release Bayonet Connection

A bayonet locking mechanism provides fast, secure and tool-free connection and disconnection, making the coupling suitable for motorsport systems where hydraulic lines or components may need to be removed or changed regularly.
6Al-4V Titanium Construction

Manufactured from 6Al-4V titanium for high strength with minimal weight, making these couplings particularly suited to weight-conscious motorcycle and motorsport applications.
AN Male Connections

Male AN connections on both coupling halves use JIC 37° flare sealing with compatible female AN fittings.
High-Pressure Hydraulic Design

Designed for demanding brake and clutch hydraulic systems, with exact operating pressure, temperature, flow and dimensional data shown for each available configuration.
EPDM Seals

EPDM internal seals provide compatibility with DOT 3, DOT 4 and DOT 5.1 glycol-based brake fluids.
Supplied as a Complete Coupling

Each coupling is supplied as a complete set with both mating halves, ready to integrate into a compatible brake or clutch 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. When connected, the internal valves open to allow hydraulic fluid to pass through. When separated, the double shut-off system closes both sides, helping to retain fluid within the system and reduce air ingress.

This makes dry break couplings particularly useful in motorsport applications where brake or clutch hydraulic lines need to be disconnected regularly for servicing, setup changes or component removal.

Designed for Motorsport Brake & Clutch Systems

Suitable for applications including motorcycle and race bike brake systems and motorsport hydraulic clutch systems where a compact quick-release connection can simplify servicing and component changes.

Do not use with Castrol SRF or DOT 5 silicone brake fluid.

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 a fluid line to be separated quickly and cleanly. Internal shut-off valves automatically close both sides when disconnected, helping to minimise hydraulic fluid loss and reduce air entering the system.
How does a dry break coupling work?
When the two halves 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 these dry break couplings used for?
They are designed for motorsport brake and clutch systems where hydraulic lines or components may need to be disconnected for servicing, setup changes or component removal.
Are these dry break couplings suitable for motorcycle brakes?
Yes. They are suitable for compatible motorcycle and race bike brake systems where a compact quick-release hydraulic connection is required.
Can these dry break couplings be used on clutch lines?
Yes. They are suitable for compatible motorsport hydraulic clutch systems and can provide a convenient disconnect point when components such as the gearbox or clutch need to be removed or serviced.
What type of connections do the couplings use?
Both mating halves use male AN connections with JIC 37° male cone flares for connection to compatible female AN fittings. See the available options for exact connection sizes.
Which brake fluids are compatible?
The couplings use EPDM seals and are compatible with DOT 3, DOT 4 and DOT 5.1 glycol-based brake fluids.
Can I use Castrol SRF or DOT 5 silicone brake fluid?
No. These couplings must not be used with Castrol SRF or DOT 5 silicone brake fluid.
What material are the dry break couplings made from?
The couplings are manufactured from 6Al-4V titanium for high strength with minimal weight.
Are both halves of the dry break coupling included?
Yes. Each coupling is supplied as a complete set with both mating halves.
Will I need to bleed the system after disconnecting the coupling?
The double shut-off design helps minimise fluid loss and air entering the hydraulic system when disconnected. The hydraulic system should still be checked after reconnection and bled if necessary before use.
Are these dry break couplings suitable for road use?
No. These Brake & Clutch Dry Break Quick Release Couplings are intended for motorsport use only and are not approved for road use.
