GE Silicone II* Gasket Caulk

Waterproof and Airtight

Keeping water and air out is a necessity when forming gasket and seals on engine parts, cars, and appliances. Otherwise, water leakage or other damage could occur. Silicone is impervious to water, meaning water can't get through it and will never break it down. Once cured, it also does not change or degrade—no shrinking, hardening, cracking or crumbling—so gaps and cracks, which could allow unwanted air to seep through, won't form.

Resists High Temperature, UV, Oil/Grease

The areas where gaskets are formed are oftentimes exposed to extreme temperatures or UV rays. These conditions can cause other sealants to lose flexibility and degrade, leaving gaps for air and water to pass. Silicone remains unaffected and can withstand extreme temperatures, harsh outdoor elements, and even oil/grease. It will not crack, crumble, or break down.

  • Forms gaskets on the engine parts, cars, appliances
  • Shrink-/crack-proof
  • Permanently flexible
100% silicone


Unlike most non-silicone caulks (water-based, acrylic, siliconized acrylic and latex), 100% silicone is permanently:
  • Waterproof—non-silicones can break down in water over time.
  • Flexible—non-silicones can become less flexible and can even freeze at low temperatures, making them more likely to crack.
  • Shrink-proof—non-silicones can shrink as the caulk dries, which can cause cracks over time.
  • Crack-proof—non-silicones can harden, crack and crumble over time when exposed to extreme heat and the sun's UV rays.

Don't Waste Time and Energy

Not all caulk is the same. Because silicone is permanently waterproof, flexible, and shrink-/crack-proof, unlike most non-silicone caulks, it won't leave gaps or cracks for air and water to seep through over time. Those leaks can lead to water damage, mold growth, and higher energy bills—all of which can translate into your lost time (when you have to do the job again), lost energy, and lost money.
