What Is a Hydraulic Fitting?
A hydraulic fitting is a component that connects hydraulic hoses and pipes, playing a crucial role in hydraulic systems. These fittings come in various types to accommodate different connection needs and angles:
- Straight Fitting: Connects a hose and pipe in a straight line.
- Elbow Fitting: Bends at a right angle to connect hoses and pipes.
- Tee Fitting: Divides the flow into a T-shape for branching connections.
- Cross Fitting: Creates a cross-shaped division for multiple connections.
- Banjo Fitting: Utilizes a screw connection for attaching hoses and pipes.
- Crimp Fitting: Secures the connection by crimping the end of the hose.
For straight, elbow, tee, and cross fittings, the process typically involves aligning and screwing the threads of the hose and pipe together. Banjo fittings are secured with a nut at the end of the hose, whereas crimp fittings are secured by compressing the hose’s end.
When selecting hydraulic fittings, it is crucial to match them with the size of the hydraulic hose. The specifications are usually marked on the hose’s surface. If the marking is not visible, measuring the hose’s outer diameter can help estimate the inner diameter, ensuring the selection of a fitting that fits correctly.
