Product Description


Forsen RTV Red silicone gasket maker is a one part RTV silicone that remains flexible and withstands high vibration. Designed 

primarily for flange sealing with excellent oil resistance on rigid flange sealing, for example on transmissions and cast metal housings.

Forms a high-quality gasket that seals the space between matched parts to prevent leakage of automotive fluids and gases. 

It meets manufacturers specifications for original equipment.


  • Seals joined parts in automotive systems - prevents leakage of antifreeze, air, oil and transmission fluid
  • Meets manufacturers' warranty requirements
  • Resists oil better than other silicone gasket makers
  • Won't interfere with sensors
  • Won't corrode 
  • Resists vibration
  • Low odor


  • Tack-free cure (time required to dry past tacky state): 30 minutes
  • Full cure (time required to reach full set): 24 hours
  • Temperature range (endurance limits of the gasket maker): -75 F to 625 F 
  • Ideal gap-filling capacity (gap sizes in which gasket maker performs best): 0.001" to 0.125"
  • Maximum gap-filling capacity (maximum gap size between joined parts): 0.240"

Applications: Valve covers, oil pans, timing covers, water pumps and thermostat housings

Applied as a gel to just one surface of the parts to be joined, silicone gasket maker forms a seal between them, keeping out contaminants. Silicone gasket maker resists oil and shop fluids, vibration, heat, and flexing of parts, replacing many conventional gaskets. Parts joined by this silicone gasket maker can easily be removed. The old gasket material comes off effortlessly, simplifying future disassembly and reassembly.


Because of their ability to flex and compress, silicone gasket makers work better than other kinds of gasket makers when the parts to be joined are made of different materials, which have different rates of expansion and contraction when temperatures change. They also work better than other types of gasket makers on stamped metal parts that can flex and in situations where clearances can be large.

This product is OEM specified: It is approved to meet specifications of original equipment manufacturers.


Directions for use:


1. For best performance bond surfaces should be clean and free from grease.

2. Moisture curing begins immediately after the product is exposed to the atmosphere, therefore parts to be assembled should be mated within a few minutes after the product is dispensed.

3. The bond should be allowed to cure (e.g. seven days), before subjecting to heavy service loads.

4. Excess material can be easily wiped away with non-polar solvents.
