What is banjo bolt?

A banjo bolt is a specialized type of bolt used in automotive and hydraulic systems. It is designed with a hollow cylindrical body, similar to a banjo, with a hole drilled through its side. The primary purpose of a banjo bolt is to connect fluid-carrying hoses, pipes, or tubes to various components, such as brake calipers, master cylinders, fuel pumps, or oil lines.

The unique design of the banjo bolt allows fluid to flow through the central hole and into or out of the component it is attached to. It consists of three main parts: the bolt with its cylindrical body, a hollow banjo fitting that surrounds the bolt, and two sealing washers or O-rings that create a tight seal between the bolt and the fitting.

Banjo bolts are commonly used in brake systems, as they allow fluid to enter and exit at a right angle, facilitating the mounting of brake hoses and calipers in tight spaces. They also help to reduce fluid pressure loss and vibration, ensuring a secure and reliable connection.

Different banjo bolt sizes and specifications are available to meet the requirements of specific applications. They are typically manufactured from high-quality materials like steel or stainless steel, ensuring strength, durability, and resistance to corrosion.

In summary, a banjo bolt is a specialized bolt used to connect fluid-carrying hoses to various components in automotive and hydraulic systems. Its unique design facilitates fluid flow and allows for secure connections in tight spaces.
