FAG SS3705 Engine Camshaft Seal

Engine Camshaft Seal for Audi and Volkswagen

FAG SS3705 is an engine camshaft seal built with a metal shell, auxiliary lip, and inner shell design for controlled sealing at the camshaft interface. It uses polyacrylate-Teflon sealing material to help maintain a tight seal where oil control matters most in Audi, Volkswagen, and select Porsche applications.

Fits a wide range of front and N/A-position applications across 1992-2018 Audi A4, A6, TT, Q5, A3, S4, S6, S8, and Volkswagen Passat, Jetta, Golf, Tiguan, and Touareg platforms. This part cross-references Dorman HELP 13722 and National 710618 for the same application.

Detailed Description

The FAG SS3705 is specified for engine camshaft sealing where precise dimensions and stable sealing contact are required. Its metal-bodied design and auxiliary lip help maintain sealing integrity at the camshaft opening, while the polyacrylate-Teflon sealing material is selected for demanding engine environments. With OE-style dimensions and broad vehicle coverage, this seal supports service work on many Audi A4, A6, TT, Q5, and Volkswagen Passat, Jetta, Golf, and Tiguan models.

Use SS3705 when replacing a worn or leaking camshaft seal on vehicles that call for the listed bore, outside diameter, and width specifications. The part number SS3705 is also referenced under global number 413 3705 100 in several applications.

What It Helps Solve

• Oil seepage at the camshaft seal area
• Contamination entering the sealed engine opening
• Loss of sealing contact from age or heat cycling
• Service issues on Audi A4, A6, TT, and related Volkswagen engines
• Fitment mismatches when replacing an OE-style camshaft seal

Installation Notes and Tips

Confirm the seal dimensions and engine code before installation. Clean the sealing surface thoroughly, inspect the camshaft and housing for wear, and install the seal squarely to avoid distortion. Verify the application by year, make, model, position, and engine notes, especially on Audi and Volkswagen vehicles with multiple engine configurations.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS3705 is engineered for contamination control and grease or oil retention at the sealing interface, with construction intended for demanding OE-style service requirements.
