WESPC Seal CH12062 for Perkins 4.236 T4.236 4.248 diesel engine

WESPC Seal CH12062 for Perkins 4.236 T4.236 4.248 diesel engine

The CH12062 Seal is a precision-engineered oil seal specifically designed for 4-cylinder diesel engine platforms, compatible with 4.236, T4.236, 4.248, and 1004-family series power units. This seal is extensively utilized across generator sets, agricultural tractors, construction equipment, and industrial power generation systems.

The seal serves as the critical barrier preventing lubricating oil leakage from rotating shaft interfaces, ensuring proper engine lubrication and preventing contamination of external components. It is compatible with naturally aspirated and turbocharged diesel engines, supporting reliable operation in high-demand stationary power, farming, and material handling applications. The seal maintains critical sealing integrity under varying temperature and pressure conditions, contributing to reduced oil consumption and extended engine service life.

The seal is manufactured from high-grade nitrile rubber (NBR) or fluoroelastomer (FKM/Viton) compounds, providing exceptional resistance to engine oils, heat, and environmental contaminants. The material formulation includes anti-aging additives and reinforcing fillers that ensure long-term dimensional stability and compression set resistance under cyclic thermal and mechanical loads.

The seal features a precision-molded elastomeric lip with integrated garter spring, maintaining optimal radial contact pressure against the rotating shaft surface. The lip design accommodates minor shaft surface imperfections while maintaining positive sealing contact pressure across the entire operating temperature range. The material resists compression set, ensuring the seal maintains its original dimensions and sealing force over extended service intervals.

The outer case is constructed from carbon steel or stainless steel, providing robust mechanical retention in the housing bore and effective heat dissipation. The case features a rubber-coated or bare metal outer surface for optimal interference fit and corrosion resistance. The seal design prevents oil leakage while excluding dust, dirt, and moisture from entering the lubrication system.

The seal maintains chemical stability when exposed to modern engine lubricants including synthetic and semi-synthetic oils, as well as oil additives and combustion byproducts. The robust construction withstands the mechanical stresses and thermal cycling encountered in diesel engines, ensuring reliable operation across diverse fuel qualities and operating conditions.
