Product Overview
The MD343563 / MD069949 (44*60*7 mm) TC double lip oil seal is designed for automotive engine sealing applications, widely used on crankshaft front and timing cover positions for Mitsubishi and Hyundai engines. Its primary function is to retain engine lubricating oil around the rotating shaft while preventing external dirt, dust, and moisture from entering.
Manufactured with oil-resistant NBR or FKM rubber compounds and an internal steel casing with a garter spring, this oil seal provides stable radial sealing performance and wear resistance. Built strictly to standard metric dimensions for a secure press-fit and dependable leak prevention during engine maintenance.
Key Features
- Double Lip TC Design: Features a primary sealing lip to retain oil and a secondary dust lip to block external contaminants.
- Oil & Heat Resistant Rubber: Available in durable NBR and FKM compounds for stable performance against engine oil and friction heat.
- Reliable Spring Retention: Internal tension spring maintains consistent radial contact pressure against the rotating shaft.
- Direct Replacement Fit: Manufactured to strict OEM tolerances for smooth installation, secure press-fit, and dependable leak prevention.
