6.4 Hydraulic Connections
To make port connections, install fittings rated for 350 bar (5000 psi). DO NOT use thread sealant. Sealing is
accomplished by using an o-ring on the fitting boss. Lubricate the o-ring prior to assembly. When designing
your hydraulic circuit, consider the factors listed in PRELIMINARY INFORMATION on page 2. For more
information about plumbing hydraulic circuits, see your Enerpac Catalog.
