Pipe Fittings

Hydraulic bite-type pipe fittings

Hydraulic bite-type pipe fittings are a type of hydraulic fitting that provides a reliable and leak-proof connection between hydraulic pipes or tubing. They are commonly used in high-pressure hydraulic systems where secure connections are essential.

Here's how they work and some key features

Bite-Type Connection: Hydraulic bite-type pipe fittings use a ferrule or sleeve that "bites" into the outer surface of the tubing when assembled. This biting action creates a secure and leak-proof connection, even under high pressure.

Pipe Fittings

Two-Piece Design: Hydraulic bite-type pipe fittings typically consist of two main components: the body and the ferrule. The body is usually a threaded fitting that screws onto the hydraulic component, while the ferrule is a collar that slides over the tubing and provides the sealing action.

Metal-to-Metal Seal: The biting action of the ferrule creates a metal-to-metal seal between the fitting and the tubing, eliminating the need for additional sealing materials such as O-rings or gaskets. This design ensures reliable sealing even in harsh operating conditions.

High Pressure Rating: Hydraulic bite-type pipe fittings are designed to withstand high-pressure applications commonly found in hydraulic systems, making them suitable for use in demanding industrial environments.

Reusable: One advantage of Hydraulic bite-type pipe fittings is that they are often reusable. If the tubing needs to be replaced or repositioned, the fitting can be disassembled, and the ferrule can be reused with a new section of tubing.

Wide Range of Sizes and Configurations: Hydraulic bite-type pipe fittings are available in various sizes (Like 6mm to 42mm) and configurations to accommodate different tubing sizes and connection requirements. They can be used in both metric and inch-based tubing systems.

Installation: Installing bite-type fittings typically involves sliding the ferrule onto the tubing, inserting the tubing into the fitting body, and tightening the fitting securely using a wrench. The biting action of the ferrule creates a tight seal as the fitting is tightened.


Hydraulic bite-type fittings offer several advantages, including,

High pressure capability: They can withstand high-pressure hydraulic systems.

Vibration resistance: The biting action provides a secure connection that is less susceptible to loosening due to vibration.

Easy installation: They can be quickly and easily assembled with basic tools, making them suitable for on-site installations.

Reusability: In many cases, the fittings can be disassembled and reused, which can be cost-effective over the long term.

Overall, hydraulic bite-type pipe fittings offer a robust and reliable solution for connecting hydraulic tubing in high-pressure applications, providing secure connections and leak-free operation.
