Elring PTFE Engine Seal 902860 Durable Design

Description

Product Overview

The Elring 902860 radial shaft seal is engineered for high‑performance engine block applications. Constructed from a dual‑layer composition of PTFE (polytetrafluoroethylene) and ACM (polyacrylic rubber), it offers exceptional chemical resistance, low friction, and long‑lasting durability. With an outer diameter of 79 mm, an inner diameter of 65 mm, and a width of 10 mm, this seal fits precisely into standard engine block housings, ensuring a tight, leak‑free barrier against oil and coolant migration. The ASW (anti‑seize wear) design further enhances sealing integrity under extreme temperature fluctuations and high‑pressure conditions.

Usage

Designed for automotive replacement engine blocks, the 902860 seal is ideal for both professional mechanics and seasoned hobbyists performing engine rebuilds, overhauls, or routine maintenance. It performs reliably in gasoline and diesel engines, as well as in high‑performance racing applications where thermal stability is critical. Install the seal in environments ranging from workshop bays to on‑site field repairs, ensuring proper alignment with the shaft and housing to maximize sealing efficiency.

FAQ

What engines are compatible with the Elring 902860 seal?

The seal fits engine blocks that require a 79 mm outer diameter and 65 mm inner diameter, commonly found in many passenger‑car and light‑truck engines. Refer to your vehicle’s service manual for exact compatibility.

Can the seal be reused after removal?

Due to the PTFE/ACM material properties, the seal can be inspected for damage and, if undamaged, reinstalled. However, for optimal performance, replacement with a new seal is recommended after major disassembly.

How does the ASW design improve performance?

The ASW (anti‑seize wear) profile reduces friction between the rotating shaft and the seal, decreasing heat buildup and extending service life, especially under high‑rpm conditions.

Is this seal suitable for high‑performance or racing engines?

Yes. The combination of PTFE’s low friction and ACM’s elasticity provides reliable sealing under the elevated temperatures and pressures typical of performance applications.

What is the warranty on the Elring 902860 seal?

Elring offers a limited warranty covering manufacturing defects for a period of 12 months from the date of purchase, provided the seal is installed according to the recommended guidelines.
