JL-DD / JL-DC — Right-Angle Hydraulic Swivel Joints

Compact right-angle swivel for high-pressure hydraulic circuits

Overview

The JL-DD and JL-DC series are right-angle hydraulic swivel joints for high-pressure circuits with low rotation or oscillation frequencies. Where supply piping meets the rotating axis at 90°, these compact swivels eliminate awkward bends and extra fittings — rated 35 MPa for ambient-temperature hydraulic oil, at speeds up to 100 rpm and media temperatures to 100 °C.

Construction is entirely stainless steel, with oil-free composite bearings supporting the larger sizes — a fit-and-forget combination that shrinks the maintenance calendar on oscillating equipment. The right-angle envelope keeps leak points to a minimum and installs in tight machine frames.

Sizing follows the model & dimension tables in the image gallery: JL04–JL32 (size 04–32) across the JL-DC and JL-DD executions, with connection sizes Rc × G from 1/4 to 2 inch and full L/A/B/d/C/H/Z dimensions plus weights. Values marked † are under final verification and are confirmed at quotation; final dimensions are confirmed on order drawings. Tell us the working pressure, medium, speed or oscillation angle and installation envelope and we will point you to the right model.

Priced by quotation — consistently below European and American equivalents. Standard models ship in 3–15 days after order confirmation, minimum order 1 unit; large-volume orders may need longer, with the exact schedule confirmed in the quotation. Manufactured under ISO 9001:2015 and shipped to 70+ countries.

Frequently Asked Questions

1 What applications are the JL-DD / JL-DC right-angle swivels designed for?

They are built for high-pressure hydraulic circuits up to 35 MPa with low rotation or oscillation frequencies (up to 100 rpm, 100 °C). Typical uses: hydraulic oil circuits where piping must turn 90°, oscillating industrial machinery, and any installation needing a compact right-angle fluid transfer.

2 Why choose a right-angle (90°) hydraulic swivel instead of an inline joint?

When the supply piping and the rotating equipment axis are perpendicular, an inline joint forces awkward bends and extra fittings. The JL-DD / JL-DC turns the flow 90° in a compact envelope — entirely stainless steel, with oil-free composite bearings on larger sizes — saving space and reducing leak points. Rated 35 MPa for ambient-temperature hydraulic oil.

3 What sizes are available and how do I pick the right model?

The range runs JL04–JL32 (size 04–32) across the JL-DC and JL-DD executions, with Rc × G connections from 1/4 to 2 inch — full dimensions and weights are in the two model & dimension tables in the image gallery. To select, send the working pressure, medium, speed or oscillation angle and installation envelope; values marked † are confirmed at quotation and final dimensions on order drawings.

4 What are the lead time and minimum order for JL-DD / JL-DC?

Standard models ship in 3–15 days after order confirmation, minimum order 1 unit. Large-volume orders may need longer; the exact schedule is confirmed in the quotation. Because these swivels often run as critical spares on oscillating equipment, we keep the standard sizes close to ex-stock terms.
