Engineered for Extreme Heat, Pressure & Corrosive Environments
AVLOK® high-temperature fittings are specifically designed for applications where durability, safety, and leak-tight performance are critical. The fittings maintain sealing integrity even during thermal expansion, pressure fluctuations, and prolonged exposure to extreme heat. The carefully selected high-temperature alloys offer excellent resistance to oxidation, creep, scaling, and corrosion, especially in environments involving aggressive chemicals and high operating temperatures. This makes AVLOK® fittings ideal for industries requiring high pressure high temperature fittings with consistent performance and reduced risk of system failure.

FAQ
High temperature fittings are special pieces of equipment designed to stay within high temperature elevation limits without compromising its structure or performance. These are usually applied in applications where temperatures exceed standard operating limits, or in an engineering, industrial machinery, steam systems, power plants, and chemical processing.
Common materials include stainless steel (like 316 or 310), Inconel, Hastelloy, titanium, and other alloys that are resistant to high temperatures and corrosion. These materials offer superior strength and thermal resistance, making them ideal for extreme conditions.
