This article provides expert, data-backed guidance on sealant use with WTA brand gaskets, easing common user concerns about installation best practices.
WTA Gaskets: Engineered Sealing Excellence

Should You Apply Sealant with WTA Gaskets?
- General Rule:
- *No sealant is required or recommended* unless specified by installation instructions.
- Exceptions:
- Certain WTA gaskets, such as oil pan or timing cover gaskets, may call for specific sealant types at the joints or corners. Always refer to manufacturer guidelines.

- Uneven sealing and loss of clamping force.
- Early gasket failure and leaks.
- Under-application (or using the wrong sealant type) can reduce sealing integrity, especially under thermal cycling.
Key Recommendations for Installing WTA Gaskets
- Always consult the WTA gasket installation guide before applying any sealant.
- Use specified sealants only in areas indicated, such as joints or challenging profile transitions.
- Maintain clean, dry, debris-free mating surfaces.
- Never substitute one type of sealant for another; compatibility is crucial for performance.
