Installing Hose Assemblies I


Review the safety precautions found in previous blog posts about “Maintaining a Safe Work Environment” as well as your equipment’s operations manual before installing hydraulic hose assemblies. Installation varies depending on coupling configurations, use of adapters, and routing.

Coupling Configurations

Male fitting to port connections can be made using four types of configurations:

§  Solid male (MP, MB, MBSPT, etc.).

§  Male swivels (MPX, MBX, MIX).

      ·         Flanges (FL, FLH, FLC, FLK).

·         Block-style adapters with Lock- nuts.

Solid Male

Solid male fittings are installed by rotating the entire hose assembly when the male thread is threaded into a port. For ease of installation and improved seal, Teflon® tape can be used on tapered threads.

If an O-ring is used, lubricate it with oil before installation. A poor seal can be the result of a dry O-ring sticking and pulling away from the sealing area.

Once hand-tight, use a wrench on the hex to properly torque the fitting. Since hose rotation is necessary, never use two solid males on the same hose assembly.
