The Loctite black 300ml pipe and thread sealant resists ageing, weathering and thermal cycling without hardening, shrinking or cracking. This product cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. It is composed of oxime silicone and requires no mixing. This product is typically used in applications with an operating range of -54 °C to 260 °C. This Loctite ready-to-use flange sealant is ideal for flanges with permanent oil contact
