JB Weld 37906 MufflerSeal Muffler Cement 6 oz Tube

J-B Weld MufflerSeal is a high-temperature muffler cement designed to prevent and seal leaks at exhaust pipe connections, seams, and gaps. This iron-reinforced paste creates a permanent, metal-containing bond that withstands the extreme heat and vibration of exhaust systems.

Key Features:

• Heat resistant up to 850°F continuous exposure
• Iron-reinforced formula for maximum strength and durability
• Dries to a cement-like hardness in 2-4 hours
• Seals leaks at pipe joints, seams, and connection points
• 6 oz plastic tube for easy application
• Ideal for mufflers, tailpipes, catalytic converters, and exhaust manifolds

This paste-based sealant is perfect for emergency exhaust repairs or permanent sealing applications. Simply apply to clean, dry surfaces and allow to cure. The metal-containing formula expands and contracts with temperature changes, maintaining a reliable seal under demanding conditions.
