Description
Overview:
These male brake tube nuts are precision‐machined metal fittings used to secure 3/16 inch (4.76 mm) brake pipes to components such as wheel cylinders, master cylinders, flexi‐hose adapters and junction blocks on hydraulic braking systems. They feature a 3/8 inch UNF (9.53 mm) external thread with 24 threads per inch (approx. 1.06 mm pitch) for a dependable, vibration‐resistant connection. The long male body offers better spanner grip and alignment during assembly. Suitable for use on cars, light commercial vehicles, trailers, agricultural equipment and plant machinery where 3/16 inch brake lines are fitted. Designed for reliability under pressure and everyday service conditions. Manufacturer Part Number (MPN): 305 108.
