What is Field Attachable Fittings?

Field attachable fittings are essential components in hydraulic systems that connect hoses to other parts like adapters, valves, or couplings. These fittings are designed for quick and easy installation, making them ideal for fieldwork and reducing downtime.

Components and Features

A typical field attachable fitting consists of two main components: the insert and the socket or collar. The insert has machined threads on its outer diameter that engage with the socket during assembly. This design allows for a secure and reliable connection. Some fittings also feature an “Easy-On” coating, which reduces the amount of torque required during assembly and increases the fitting’s reusability.

Moreover, field attachable fittings can be categorized into skive and non-skive types. Skive fittings require the removal of part of the hydraulic hose cover or inner tube before assembly, while non-skive fittings are designed for immediate assembly without any pre-treatment. This distinction is crucial because it affects both the assembly time and the fitting’s performance.
