These fittings have a tapered thread and are made from steel, brass, or stainless steel. NPT fittings are suitable for low to medium-pressure systems and are used in applications where leakage is acceptable.

4. BSP Fittings: BSP (British Standard Pipe) fittings are widely used in the UK and are available in various sizes, ranging from 1/8″ to 4″. These fittings have a tapered thread and are made from steel, brass, or stainless steel. BSP fittings are suitable for low to medium-pressure systems and are used in applications where leakage is acceptable.

5. Metric Fittings: Metric fittings are widely used in Europe and are available in various sizes, ranging from 4mm to 42mm. These fittings have a straight thread and are made from steel, brass, or stainless steel. Metric fittings are suitable for low to medium-pressure systems and are used in applications where leakage is acceptable.

6. Flange Fittings: Flange fittings are used to connect hoses, pipes, and other parts in a hydraulic system using bolts and nuts. These fittings have a flange at one or both ends and are made from steel, brass, or stainless steel. Flange fittings are suitable for high-pressure systems and are widely used in applications where a secure connection is required. Flange fittings are available in various sizes and types, including slip-on flanges, threaded flanges, and weld neck flanges.

7. Elbow Fittings: Elbow fittings, also known as 90-degree fittings, are used to change the direction of the hose or pipe in a hydraulic system. These fittings have a 90-degree angle at one end and are made from steel, brass, or stainless steel. Elbow fittings are available in various sizes and types, including male elbow fittings and female elbow fittings.

8. Tee Fittings: Tee fittings, also known as T-fittings, are used to split or combine the flow of fluids in a hydraulic system. These fittings have a T-shaped body and are made from steel, brass, or stainless steel. Tee fittings are available in various sizes and types, including male tee fittings and female tee fittings.

9. Cross Fittings: Cross fittings, also known as four-way fittings, are used to split or combine the flow of fluids in a hydraulic system. These fittings have a cross-shaped body and are made from steel, brass, or stainless steel. Cross fittings are available in various sizes and types, including male cross fittings and female cross fittings.

10. Plug Fittings: Plug fittings are used to close off the end of a hose or pipe in a hydraulic system. These fittings have a cylindrical shape and are made from steel, brass, or stainless steel. Plug fittings are available in various sizes and types, including male plug fittings and female plug fittings.

11. Quick Disconnect Fittings: Quick disconnect fittings, also known as quick release couplings, are designed for fast and easy connection and disconnection of hoses and pipes. These fittings come in various shapes and sizes and are made from steel, brass, or stainless steel. Quick disconnect fittings are suitable for low to medium-pressure systems and are widely used in applications where frequent connection and disconnection is required.

12. Adapter Fittings: Adapter fittings are used to connect different types of fittings and hoses. These fittings come in various shapes and sizes and are made from steel, brass, or stainless steel. Adapter fittings are widely used in hydraulic systems to connect hoses and pipes of different sizes and types.
