Deublin swivel joints
Let Pipework Move Without Leaking
Swivel joints let pipes turn and flex where they meet moving machinery – press platens, lifting arms, loading arms. They outlast flexible hose and lose less pressure.

- 360°turning
- 10°angle (self-aligning joints)
- 1"–6"plane swivel joint sizes
- 86 barmax. cold working pressure (1")
Why Deublin swivel joints
Safer Than Hose
No Burst Hoses
Removes the risk of leaking joints and failed hoses.
Less Pressure Drop
A full-bore joint loses less pressure than a hose.
Easy to Repair
Three-piece design; the seal can be changed without removing the bearings.
Strong Bearings
Two rows of widely spaced bearings carry heavy loads.
The range
Plane Swivel Joints
Turn through 360° in one or more planes, for oil, water, air, gas and chemicals. Order code: style, then material (0 = carbon steel), size code and seal code – for example BD-52410-16-01.
| Styles (41, 42, 43 = joint shape) | Ends | Sizes | Max. cold working pressure |
|---|---|---|---|
| BD-5241 / BD-5242 / BD-5243 | Threaded NPT (or BSPT) | 1", 1½", 2", 3" | 1,250 psi / 86 bar (1"); 1,000 psi / 69 bar (1½"–3") |
| BD-5141 / BD-5142 / BD-5143 | Welded | 3", 4", 6" | 1,000 psi / 69 bar (3"–4"); 750 psi / 52 bar (6") |
| BD-5341 / BD-5342 / BD-5343 | ANSI 150 lb flanges | 3", 4", 6" | 275 psi / 19 bar |

Seal Options (Plane Swivel Joints)
The last two digits of the order code.
| Code | Seal | Temperature |
|---|---|---|
| 01 | Buna-N | −40 to 107 °C |
| 02 | PTFE | −30 to 162 °C |
| 06 | Viton | −30 to 150 °C |
The range
Self-Aligning Swivel Joints
Turn through 360° and tilt up to 10°, for steam, hot oil, water, and steam and water in turn.
| Series | Material | Sizes |
|---|---|---|
| Standard Series (BE-32000 to 32003) | All bronze | ½", ¾" |
| Standard Series (BE-32007 to 32011) | Malleable iron with bronze nut and ball | ½" to 1½" |
| Series 600 (BE-33004 to 33010) | All steel | 1¼", 1½" |
| “Non-flex” collar versions | As above | Same styles and sizes |
How to choose
Four Questions to Pick a Swivel Joint
Turn Only, or Turn and Tilt?
Plane swivel joints turn; self-aligning joints also tilt up to 10°.
What Runs Through It?
Choose the seal for the media and temperature.
How Does It Connect?
Threaded, welded or flanged ends.
What Pressure?
Check the working pressure for the size – larger joints are rated lower.
How it works
How Swivel Joints Work
A swivel joint lets pipework turn and tilt where it meets moving machinery, so you don’t need a flexible hose there.
What’s Inside
A spring holds a ball against a gasket inside the casing. The ball turns a full circle and tilts up to 10°, and the spring keeps it sealed as it moves.

Four Styles
Straight or elbow, with the threaded ends where your pipework needs them.

Stopping the Tilt
Where you only want the joint to turn, a non-flex collar stops it tilting – used at the top of a joint group so the pipework doesn’t sag.
