Sensor-safe and low odor, it ensures reliable, vibration-resistant seals on valve covers, oil pans, and more, making it the #1 choice for professional-grade gasket sealing.

## Description

Optimum black is ideal for use with valve covers, oil pans, oil pumps, intake manifold end seals, timing gear covers and differential covers.

Review: Gasket maker. - Easy to use. Perfect for assembling multiple parts together.
Review: Excellent sealer with real grip - I can't say this stuff is easy to remove once applied as the only time I had to remove a piece I had used the product on it put up a heck of a fight coming off. That proved that it had created a tight seal which is what I wanted. Vibration wasn't going to lossen it that's for sure. Application can be messy if you get in a hurry but its ability to create a tight seal with a firm holding power would be hard to duplicate this side of a weld.

### ⭐⭐⭐⭐⭐ Gasket maker.
*by J***C on November 9, 2025*

Easy to use. Perfect for assembling multiple parts together.

### ⭐⭐⭐⭐⭐ Excellent sealer with real grip
*by R***T on March 15, 2023*

### ⭐⭐⭐⭐⭐ Good gasket maker, but watch the cure time
*by A***4 on April 10, 2023*

I have used Permatex products for years. I tried the Optimum Black because it's supposed to have the highest oil resistance. The product works well. The only issue is that you have to be careful of the cure times. At lower temperatures this sealant will take more than 24 hours to cure. I used it on a valve cover in a garage that was 45 degrees and it took several days to fully cure.
