Metric Stainless Steel Bleed Nipples for Brake & Clutch Systems

Designed for bleeding air and old fluid from hydraulic brake and clutch systems, our metric stainless steel bleed nipples provide a durable and corrosion-resistant replacement for brake calipers, master cylinders, clutch cylinders and other compatible hydraulic components.

Why Choose Our Metric Bleed Nipples?

303/304 Stainless Steel Construction

Manufactured from 303/304 stainless steel for excellent strength, durability and corrosion resistance in demanding brake and clutch applications.
Multiple Metric Sizes

Available in a range of metric thread sizes to suit compatible brake, clutch and hydraulic components. Exact thread sizes and dimensions are shown in the available options.
Standard, Short & Extended Versions

Selected thread sizes are available in alternative lengths, helping to match applications where clearance or component depth differs from a standard bleed nipple.
Suitable for Brake & Clutch Systems

Suitable for compatible brake calipers, brake master cylinders, clutch master cylinders, clutch slave cylinders, ABS modules and other hydraulic components.
Optional Dust Cover

Add a bleed nipple dust cap to help protect the bleed nipple from dirt, moisture and road debris between servicing.

What Does a Bleed Nipple Do?

A bleed nipple provides a controlled outlet for removing trapped air and old hydraulic fluid from a brake or clutch system. During bleeding, the nipple is opened to allow fluid and air to escape before being closed again to seal the hydraulic circuit.

Choosing the Correct Bleed Nipple

Always match the thread size and physical dimensions of the replacement bleed nipple to the component it is being fitted to. Components using the same nominal thread can still require different nipple lengths, so check the available dimensions against the original part before ordering.
