The “HS” series in-line swivel is the latest product addition to the broadest line of swivel joints in the industry. Introduced in the second quarter of 2010, this series is designed to operate at pressures up to 5,000 psi with a 4:1 safety factor. An improved bearing design along with dual ball races, higher strength alloy steel and other design features allow the “HS” series to achieve extremely long life and operate in severe applications.

This series is being introduced in sizes –4 through –16 and with only limited port options at this time. If you require other size/port combinations not listed, we urge you to contact customer service with your requests.

CAUTION:
Do not attempt to disconnect and disassemble swivels under pressure. Do not remove the swivel barrel from stem while under pressure. Do not attempt to operate damaged swivels and do not operate swivels displaying fluid leak and/or obvious bearing wear. Consider that a selected swivels rated pressure cannot exceed the lowest rating of the swivel and of it’s selected ports. Refer to Safety Information, Selecting and Using Hydraulics, Inc. Swivel Joints.

Pressure Limitations:
Maximum working pressure for “HS” Series swivels is dependant on port options chosen; however, connecting plumbing may be rated higher or lower than that of the swivel. The rated working pressure of a fluid power system should not exceed the lowest rated component therein.

Installation Information:
Hydraulics, Inc. swivel joints are generally considered for low speed rotation as encountered in fluid power systems. Maximum speed of rotation depends upon system environment, with fluid types and extreme conditions related to temperature and pressure being of prime consideration. Questionable applications should be proven by laboratory or prototype testing. Contamination at installation should be avoided and connecting plumbing should not cause undue loading. The swivel should not be used as a load bearing or structural member. Refer to Safety Information - Selecting and Using Hydraulics, Inc. Swivel Joints for additional information.

Options:
Swivels shown in this catalog are considered standard to Hydraulics, Inc. For other requirements relative to pressure ratings, port options, or sizes not shown in this catalog, please contact us. Optional seal materials are available.
