LJ-PT™ Rotary Joints
The LJ-PT rotary joint is designed for steam service and is commonly used to upgrade LJ rotary joint installations. The LJ-PT uses a balanced seal impregnated with antimony to provide longer operating life and compensate angular misalignment. The PT design provides reduced seal loading and increased seal life at higher speeds. The full-flow design reduces pressure-drop through the steam joint and no special tools are required for installation. The LJ-PT is rated up to 450° F (232° C), 225 psig (15 bar), and 400 RPM.
