Sealants

Sealants and gasket makers are critical for achieving leak-free, durable seals in engine, transmission, and fluid systems. Whether you're replacing a valve cover gasket, sealing threads on oil pan bolts, or bonding differential covers, choosing the right formula ensures compatibility with the surface material, operating temperature, and chemical exposure.

  • RTV Silicone: High-temperature, flexible cure; ideal for stamped steel or cast aluminum covers.
  • Anaerobic Sealants: Cures in the absence of air; perfect for machined flanges and threaded fittings.
  • Thread Sealants & Pipe Dope: Prevents galling and seals tapered pipe threads against liquids and gases.
  • Specialty Sealants: Fuel-resistant, high-pressure, or sensor-safe formulations for specific applications.

Always refer to your vehicle service manual for OEM recommendations, and select a product that matches your assembly environment.
