Crankshaft Oil Seal

The TP-SH crankshaft oil seal is a precision-engineered critical engine component. Its core mission is to form a durable, reliable barrier between the rotating crankshaft and the stationary engine block, effectively sealing engine oil within the crankcase and preventing harmful contaminants (dirt, dust, water, debris) from entering the engine's vital lubrication system.

✅ Robust Construction: Features a rigid outer metal case for a secure, leak-proof press-fit installation into the engine block or timing cover.

✅ Advanced Sealing Lip: Utilizes high-performance elastomers (NBR, FKM/Viton®, VMQ, ACM) engineered for exceptional flexibility and sealing precision against the crankshaft.

✅ Garter Spring: Incorporates a corrosion-resistant coiled garter spring to maintain consistent radial pressure on the sealing lip, ensuring optimal contact and compensating for minor wear or shaft runout.

✅ Integrated Dust Lip (Common on Front Seals): Many TP-SH front crankshaft seals include an additional outer dust lip for superior protection against abrasive contaminants, significantly enhancing seal longevity.

✅ Premium Material Selection: TP-SH seals are crafted from materials rigorously.
