The LJ-PT uses a balanced seal impregnated with antimony to provide longer operating life and adjust for 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.
