1-1/4″ Silver 6000 Psi Swivel Coupling (Style 10 & Style 20)
Industrial high-pressure fluid circuits demand flexible, leak-free articulation to accommodate heavy mechanical vibrations, structural misalignments, and continuous rotational stress. Standard solid pipe setups quickly succumb to metal fatigue, creating massive blowout risks. Shanghai PME Industrial manufactures professional-grade 6000 psi swivel coupling elements engineered to provide dependable 360-degree rotational movement while safely containing severe hydraulic spikes.
Available in a versatile 1-1/4″ size with a premium silver protective zinc-plating finish, these flow components are configured in both Style 10 (three planes of rotation with three swivel joints) and Style 20 (single plane of rotation with one swivel joint). Featuring precision-machined dual ball races and elastomeric packing seals, our high pressure swivel couplings ensure smooth mechanical swiveling under maximum loaded bending moments.

Style 20 Short Radius Swivel Coupling Configuration
Side-by-Side Comparison: Style 10 vs. Style 20 Swivel Joints
Technical Evaluation: Long Radius vs. Short Radius Configurations
When integrating an style 10 swivel joint or style 20 setup into high-pressure flow lines, engineers must specify the inner bend profile: Long Radius (LR) or Short Radius (SR). While Long Radius loops provide a gentler, more sweeping internal fluid curvature that minimizes internal turbulence and velocity-induced wall thinning, specific site parameters mandate the use of a short radius architecture.
Why Do Critical Engineering Projects Specify Short Radius Joints?
The choice to deploy a specialized short radius swivel joint is dictated by precise space constraints and localized fluid dynamics:
• Severely Restricting Enclosures: In dense truck-mounted manifolds, offshore fracturing skids, and tight wellhead control panel cabinetry, every millimeter matters. Long radius joints fail to physically clear adjacent hardware. A short radius design delivers an ultra-compact footprint, enabling 90-degree flow directional shifts within a minimized geometric envelope.
• High-Pressure Mechanical Rigidity: Due to the shorter moment arm of the SR elbow profile, the overall joint experiences decreased bending leverage under massive tension loads. In clean, non-abrasive high-pressure oil or water lines operating at 6000 PSI, the short radius unit offers outstanding structural rigidity without the added bulk.
100% Cross-Interchangeability with FMC Chiksan® & Major Brands
To avoid costly modifications or proprietary component lock-ins during field swapouts, PME Industrial’s style 20 swivel coupling lineup is precision-machined to achieve absolute cross-compatibility with global standard brands like FMC Chiksan®.
Our internal ball-bearing tracks, critical face-to-face installation limits, and high-pressure thread dimensions exactly mirror international component blueprints. This guarantees that your procurement desk can introduce PME 1-1/4″ silver couplings directly into preexisting FMC fluid lines as a seamless, high-performance, and cost-effective high pressure swivel joint replacement without altering any plumbing geometry.
