Description
xOverview
Permatex 51813 Anaerobic Gasket Maker is a non-corrosive sealant designed to pair with aluminum, iron, and steel flanged mating surfaces. This red gasket maker is ideal for on-the-spot and emergency repairs when a traditional gasket isn’t available. It fills gaps up to 0.015 inches and cures to a solvent-resistant seal that holds up under service without tearing or decaying.
Housed in a compact 50 ml tube, the product is crafted for precise application and reliable performance in a variety of environments. The material is OEM-specified, offering compatibility with common automotive and machinery assemblies. Packaging may vary, but the formulation remains focused on creating a durable, flexible seal that supports steady disassembly when needed.
