A compression nut, also known as a union nut, is an essential hydraulic brake fitting used to secure the brake hose to the brake lever or calliper. When tightened, the nut compresses the olive onto the hose, creating a secure, leak-free hydraulic seal.
Ideal for replacing damaged, rounded, or corroded fittings during brake hose installation, shortening, or servicing.
Features
Genuine Shimano-style hydraulic brake fitting
Creates a secure, leak-free connection between hose and brake component
Precision M8 × 0.75 thread for Shimano (and other) hydraulic brake systems
Perfect for brake hose replacement and servicing
Durable corrosion-resistant construction
Specifications
Type: Compression Nut / Union Nut
Thread Size: M8 × 0.75
Material: Steel
Colour: Silver
Compatibility: Shimano, SRAM/Avid, Hayes, Tektro/TRP, Hope and older style Magura hydraulic brake systems using M8 × 0.75 hose fittings
Package Includes
1 × Shimano Compression Nut (Union Nut)
Important Note
Compression nuts, olives, and inserts are generally considered single-use components. For best results and a reliable seal, we recommend replacing the olive and insert whenever a brake hose is disconnected or shortened.
TB Tech Tip
When installing a new hose, always use a new olive and insert and torque the compression nut to the manufacturer’s specification to prevent leaks and ensure optimal braking performance.
