LJ-PT Rotary Joints

Request Product Information

The LJ-PT rotary joint is designed for steam service and is commonly used to upgrade the LJ rotary joint installation. The LJ-PT uses a balanced seal impregnated with antimony to provide longer operating life and 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 232° C (450° F), 15 bar (225 psig), and 400 RPM.
