Whether you’re working on a classic Mercedes, a modern Nissan, or any vehicle that requires a reliable camshaft seal, this part delivers unmatched durability and fit.

Key Features

• Material Excellence: Crafted from high‑grade fluorinated rubber (FPM) combined with an ACM (acrylic copolymer) core, the ring resists oil degradation, temperature extremes, and chemical exposure.
• Exact Dimensions: The standard size of 28 mm diameter × 42 mm width × 5 mm thickness ensures a perfect fit on most OEM camshaft housings.
• Dual‑Side Sealing: Both the front and rear faces are engineered for optimal contact, providing a hermetic seal that withstands high pressure and vibration.
• Corrosion Resistance: The FPM outer layer resists corrosion from oil additives and combustion byproducts, extending service life even in aggressive environments.
• Easy Installation: Designed for quick removal and replacement without special tools, the ring’s profile matches OEM specifications to avoid over‑compression or under‑seating.

Installation Guide

1. Preparation: Remove the camshaft housing cover and clean all mating surfaces with a solvent to eliminate oil residue.
2. Inspect the Seal: Verify that the ring’s inner diameter matches the camshaft shaft. Any deviation can cause leaks.
3. Positioning: Slide the seal onto the camshaft, ensuring it sits flush against the housing without twisting.
4. Reassembly: Replace the camshaft cover and tighten to the manufacturer’s torque specification.
5. Test Run: Start the engine and monitor for any oil leakage around the camshaft area. A properly installed ring should show no signs of seepage.

Maintenance Tips

• Regularly inspect the seal during routine maintenance checks, especially if you notice a drop in oil pressure or an oily smell.
• Avoid using harsh chemicals on the seal’s surface; mild cleaners are sufficient for cleaning.
• If the engine operates under extreme conditions (high altitude, heavy load), consider replacing the seal sooner to preempt failure.
