The John Crane Type 59B Replacement Seal is a high-performance, general-purpose DIN-balanced, multispring PTFE wedge mechanical seal, specifically engineered for demanding industrial applications. It is part of John Crane’s Type 59 series—a renowned lineup designed to comply with DIN 24960/L1K, ISO 3069, and API 610 standards, ensuring compatibility with a wide range of rotary equipment in chemical, petrochemical, refinery, and pharmaceutical industries
At its core, the Type 59B features a hydraulically balanced seal face, which significantly lowers mechanical load on seal faces during operation at higher pressures. This balancing reduces friction and heat generation, prolonging both seal lifespan and reliability under extreme conditions
