The inlet flange is a machined connector designed to join pipes, hoses, or components to an intake port. Typically made from carbon steel, stainless steel, or aluminum, it features bolt holes and a raised or flat sealing face for gasket integration. Precision-machined surfaces ensure leak-proof connections under pressure or vacuum. Common applications include pump inlets, valve assemblies, compressor intakes, and exhaust system entries. Available in various standards (ANSI, DIN, JIS) and custom configurations, the inlet flange provides reliable, accessible mounting for fluid or gas entry points in industrial systems
