Permatex Ultra Black RTV Silicone Gasket Maker, 3 oz, Sensor-Safe Non-Corrosive Formula
Permatex Ultra Black RTV Silicone Gasket Maker, 3 oz, Sensor-Safe Non-Corrosive Formula
Permatex Ultra Black RTV Silicone Gasket Maker is a 3 oz silicone sealant built for applications that demand strong adhesion and long-term durability under exposure to oils and vibration. It uses a patented adhesion system that delivers outstanding flexibility along with superior oil resistance, so the seal stays flexible and intact rather than hardening and cracking over time. The formula is sensor-safe, non-corrosive, and low-odor, meeting OE silicone gasket specifications, which makes it suitable for use around oxygen sensors and other sensitive automotive electronics without risking damage or false readings.
This gasket maker is designed for sealing timing covers, transmission pans, and oil pans, where a durable, oil-resistant seal is essential to prevent leaks under ongoing thermal cycling and engine vibration. Because it resists automotive fluids and shop chemicals in addition to oil, it holds up in the harsh under-hood environment where lesser sealants break down. The black color matches OEM gasket material for a factory-correct appearance on visible engine components.
