What is a Double Banjo Bolt?

A double banjo bolt is a hollow fastener designed to connect two banjo fittings to a single hydraulic port. Its dual-channel design allows fluid to flow through both fittings while maintaining a high-pressure seal – essential in complex brake and clutch systems commonly used in motorsport.

Installation

Each installation requires three copper crush washers (not included) – one between each banjo fitting and one on each outer side. For motorsport use, secure the bolt with 0.8mm stainless lockwire through the pre-drilled hex head for maximum safety and compliance.
