Inner Rear Hub Oil Seal with OE Fitment Durable NBR/FKM Rubber Prevents Brake Contamination for Isuzu 700P NPR 4HK1

The Inner Rear Hub Oil Seal (OEM Numbers: 8-94336317-0 / 8943363170) is a premium-quality, direct replacement sealing component designed for the rear wheel hub of Isuzu 700P, NPR, and ELF series trucks equipped with 4HK1, 4BD1, or 4HE1 diesel engines.

Function: Prevents lubricant leakage from the rear wheel hub assembly and blocks contaminants from entering the bearing cavity. Essential for rear axle reliability on Isuzu 700P/NPR trucks with 4HK1/4BD1/4HE1 engines.

• OE Fitment: Manufactured to Isuzu dimensional and material specifications for perfect press-fit and leak-free seal
• Precision Sealing Lip: Computer-designed lip geometry with consistent garter spring tension ensures reliable sealing
• Durable Rubber Compound: NBR (nitrile) rubber resists gear oil, heat (up to 120°C), and aging
• Rigid Metal Case: Carbon steel case prevents deformation during installation
• Secondary Dust Lip: Provides additional protection against dirt and water ingress
• Prevents Brake Contamination: Stops oil from reaching brake drums/shoes, preventing brake fade
• Extends Bearing Life: Retains lubricant and excludes contaminants, doubling wheel bearing service life
• Cost-Effective: Affordable seal prevents expensive axle and brake repairs
