Product Features
Permatex Ultra Black offers several key features that make it a reliable choice for sealing and gasketing tasks. Understanding these features helps ensure proper use and maximum effectiveness. This product is designed for durability, flexibility, and resistance to harsh conditions.
Waterproof Seal
Permatex Ultra Black creates a strong waterproof seal. It prevents water and moisture from leaking through joints. This feature protects engines and machinery from damage caused by water intrusion. The seal remains intact even under wet conditions.
Flexibility And Durability
The product stays flexible after curing, allowing it to move with parts. This flexibility prevents cracks and breaks over time. It also withstands vibration and temperature changes without losing strength. Durability ensures a long-lasting seal for various applications.
Oil Resistance
Permatex Ultra Black resists oil and other automotive fluids. It does not break down or soften when exposed to oils. This makes it ideal for sealing oil pans, valve covers, and transmission cases. The oil resistance helps maintain a secure, leak-free seal.
Material Compatibility
This gasket maker works well on many materials like metal, glass, rubber, and plastic. It bonds tightly to these surfaces without damaging them. The compatibility allows use in different parts of vehicles and equipment. It also cures at room temperature for easy application.
Preparation Steps
Proper preparation is crucial before applying Permatex Ultra Black. It ensures a strong, lasting seal. The steps below help you get the surface ready. Follow them carefully for the best results.
Surface Cleaning
Start by cleaning the surface thoroughly. Remove dirt, oil, and grease using a clean cloth and a suitable cleaner. A clean surface helps the gasket maker stick better. Avoid using harsh chemicals that may damage the material.
Removing Old Gaskets
Old gaskets can prevent proper sealing. Carefully scrape off any remaining gasket material. Use a plastic scraper or a gasket remover tool to avoid scratching the surface. Make sure no bits of old gasket remain in the grooves.
Ensuring Dryness
Make sure the surface is completely dry before applying the gasket maker. Moisture can prevent proper curing and cause leaks. Use a dry cloth or let the surface air dry. Check twice to avoid trapping water under the seal.
Application Tips
Proper application of Permatex Ultra Black is key for a strong, lasting seal. Follow these tips for best results. Take time to prepare surfaces and apply carefully. Small steps prevent leaks and damage later on.
Applying The Bead
Apply a continuous bead of Permatex Ultra Black on the clean surface. Keep the bead steady and even for a smooth seal. Avoid stopping and starting to prevent gaps. Use a caulking gun for better control. After application, wait about one hour before tightening bolts.
Avoiding Common Mistakes
Do not apply too much or too little sealant. Avoid contaminating the bead with oil or dirt. Do not wipe away the bead after applying. Avoid disturbing the seal before it cures fully. Follow the curing time recommended by the manufacturer to avoid leaks.
Recommended Bead Size
Use a bead about 1/8 to 1/4 inch wide. This size creates a flexible, strong seal without excess mess. Larger beads may take longer to cure and can squeeze out under pressure. Smaller beads may not fill gaps properly. Adjust the size based on the joint width.

Curing Process
The curing process is vital for Permatex Ultra Black to form a strong, durable seal. It involves time and specific conditions for the gasket maker to harden properly. Proper curing ensures the seal resists oil, water, and vibration. Understanding the curing stages helps achieve the best results.
Tack-free Time
Tack-free time is when the surface of the sealant feels dry to touch. For Permatex Ultra Black, this usually takes about 20 to 30 minutes. At this point, the gasket maker is still soft but will not stick to your fingers. It allows you to handle parts carefully without disturbing the seal.
Full Cure Time
Full cure time means the sealant has hardened completely. Permatex Ultra Black needs up to 24 hours to cure fully. During this time, the sealant forms a flexible, oil-resistant gasket. Avoid moving or stressing the sealed parts until the cure is complete. This ensures a reliable, leak-proof seal.
Factors Affecting Cure
Several factors influence how fast Permatex Ultra Black cures. Temperature plays a big role; warmer conditions speed up curing. Humidity also helps because the product cures by reacting with moisture in the air. Thicker layers of sealant take longer to cure than thin ones. Proper ventilation improves curing speed and quality.
Bolt Torquing Guidelines
Proper bolt torquing is essential for a strong, leak-free seal with Permatex Ultra Black. Following the right steps prevents damage and ensures the gasket maker performs well. This section explains key guidelines for torquing bolts correctly.
Waiting Before Torquing
After applying Permatex Ultra Black, wait about one hour before torquing bolts. This waiting time lets the sealant start setting. It helps create a better seal and reduces the chance of leaks. Avoid torquing bolts immediately after application.
Torque Specifications
Always follow the torque values given in your vehicle’s manual. Over-tightening can damage parts or squeeze out the sealant. Under-tightening can cause leaks or loose bolts. Use a calibrated torque wrench to apply the exact amount of force.
Retorquing Advice
Permatex Ultra Black cures fully with exposure to moisture. Once cured, retorquing is not necessary. Do not retorque bolts after the sealant has dried completely. Retorquing too soon may break the seal or cause leaks.

Troubleshooting
Troubleshooting common issues with Permatex Ultra Black helps ensure a strong, lasting seal. Understanding why problems occur aids in fixing them quickly. Below are key areas to check if the seal does not perform as expected.
Seal Failures
Seal failures often result from surface contamination. Dirt, oil, or old gasket material can prevent proper adhesion. Clean surfaces thoroughly before applying the gasket maker. Also, check for uneven or damaged surfaces that may cause leaks. Applying too thin a bead reduces sealing strength. Use a consistent, even bead for best results.
Curing Issues
Permatex Ultra Black cures by exposure to moisture in the air. Low humidity slows the curing process and weakens the seal. Ensure adequate airflow and moisture during curing. Avoid covering the seal until it is tack-free. The full cure time is 24 hours, but partial curing usually occurs within one hour. Do not disturb the gasket before this time.
Improper Application Effects
Applying the gasket maker incorrectly can cause poor sealing. Over-applying causes excess squeeze-out and mess. Under-applying leaves gaps prone to leaks. Avoid applying to hot surfaces, which can affect curing. Tighten bolts in stages after the gasket becomes tack-free. Following the vehicle’s torque specifications protects the seal from damage.
Safety Precautions
Using Permatex Ultra Black requires attention to safety. This ensures a smooth, hazard-free experience. Follow simple safety steps to protect yourself and others.
Ventilation Needs
Work in a well-ventilated area. The product releases fumes that can irritate your eyes and throat. Open windows or use fans to keep air moving. Avoid breathing in fumes for long periods.
Skin Contact
Avoid direct contact with skin. Wear gloves to prevent irritation. If the sealant touches your skin, wash it off with soap and water quickly. Do not use solvents to remove it from skin.
Storage Tips
