FAQs

What is the material of the Elring 498.701 tape?

This is a white PTFE (polytetrafluoroethylene) sealing tape.

Can this tape be used in the chemical industry?

Yes, it is designed for use in the chemical industry and follows DIN/ISO EN 751/3 standards.

Does it replace Mercedes-Benz OEM 000 989 40 98?

Yes, it is a direct replacement for both Mercedes-Benz 000 989 40 98 and A 000 989 40 98.

What is the total length provided on one reel?

Each reel contains 12 meters of sealing tape.

Is this safe for use with extreme heat?

The tape is rated for continuous use in a temperature range from -200°C to 280°C.

How many times should I wrap the thread?

Typically, 2 to 3 full wraps are sufficient for most standard threaded fittings.

Troubleshooting

Seal is still leaking after application

Ensure the tape was wrapped in the direction of the thread and increase the number of wraps slightly to account for thread depth.

Fitting is difficult to screw in

You have likely applied too many layers of tape. Remove the fitting, strip the old tape, and apply a thinner, uniform layer.

Pros and Cons

Pros

  • Resistant to a vast temperature range
  • Meets rigorous industrial DIN/ISO standards
  • Excellent chemical compatibility
  • Direct fit for specific Mercedes-Benz OEM requirements

Cons

  • Requires careful application to prevent over-wrapping
  • Not intended for non-threaded sealing applications
  • White tape can be difficult to see on certain metallic surfaces

Setup, Compatibility & Care

Before applying the tape, ensure that all threads are clean, dry, and free of oil or debris to allow for proper adhesion. Wrap the tape tightly around the male thread in the direction of the tightening motion, typically applying 2 to 3 layers for a sufficient seal. Avoid over-wrapping, as excessive thickness can cause the plastic housing or fitting to crack during installation. For storage, keep the reel in a cool, dry place and ensure the protective cap is kept on the spool to prevent dust contamination of the adhesive surface.
