Loctite SI 59330 Superflex Black RTV Silicone Adhesive Sealant – 80 ml Tube

Loctite SI 59330 Superflex is a one-part, general-purpose RTV silicone sealant formulated for creating tough, leak-proof gaskets and seals on metal flanges, pumps, valves, threaded fittings, and most rigid plastics. Its thixotropic black paste won’t sag or slump—perfect for overhead or vertical applications—and cures at room temperature to form a flexible rubber seal that resists oil, water, UV, and ozone. Rated from –65 °F to +450 °F, it provides reliable performance in both indoor and outdoor environments. The standard 80 ml cartridge fits all caulking guns for precise, mess-free application, and achieves full strength in 24 hours
