Loctite 598 RTV Black Silicone Product FAQ

What is this RTV silicone gasket maker intended for?

Loctite 598 is made for high-temperature, oil-resistant gasket applications. It replaces traditional gaskets on valve covers, timing covers, and oil pans. The black silicone forms a durable, flexible seal. It's suited for automotive and industrial use.

How does it perform under oil and heat exposure?

This sealant withstands prolonged contact with motor oils and temperatures up to 625°F intermittently. It doesn't degrade, shrink, or become brittle. It performs reliably in engine compartments and hot surfaces. It's oxygen sensor safe after curing.

What are the application steps for best results?

Apply a uniform bead to one surface and assemble parts immediately. Let it cure for 24 hours before exposing to fluids. Do not overtighten fasteners during cure. Avoid fuel contact until fully cured.
