Basic Concepts of Banjo Connector Screws

A banjo connector screw is a type of fitting used to connect hoses or pipes in fluid systems. It typically consists of a bolt, a banjo fitting (a small, flat, oval-shaped piece), and washers or seals. The banjo fitting is clamped between two surfaces, creating a seal that allows fluid to pass through while preventing leaks. These connectors are widely used in automotive and industrial applications due to their reliability and ease of installation ¹.

Purpose and Role in Truck Operation

This Cummins part is integral to the operation of heavy-duty trucks. It is used in hydraulic systems to connect hoses that transfer hydraulic fluid, in fuel systems to link fuel lines, and in lubrication systems to ensure proper oil flow. The screw’s design allows for secure connections that withstand high pressure and vibration, which are common in truck operations ².

Key Features

The 4325473 features several design elements that enhance its performance and durability. It is made from high-quality materials resistant to corrosion and wear. The screw has a specific thread type that ensures a tight fit, and it incorporates sealing mechanisms such as washers or O-rings to prevent leaks. Its design specifications are tailored to meet the demanding requirements of heavy-duty applications.

Benefits

Using the 4325473 offers several advantages. It provides improved sealing compared to other types of connector screws, ensuring a leak-free connection.
