metal gasket
The Metal Buna gasket is a sealing element composed of an outer metal ring and an inner elastomer (NBR) ring. It is used to achieve a watertight seal in threaded and flanged joints. The main function of the metal ring is to withstand high pressure and limit deformation of the rubber. This design combines the mechanical strength of metal with the elasticity and sealing capacity of nitrile rubber.
Main features :
The Buna metal gasket is a sealing element composed of a metal ring that provides rigidity and mechanical strength, combined with an NBR lip that ensures a fluid-tight seal. This combination offers a durable, pressure-resistant seal with excellent performance against oils, fuels, greases, and industrial fluids.
The metal body provides dimensional stability and prevents deformation during tightening, while the rubber adapts to the contact surfaces.
The rubber seal deforms when tightened, and its reaction force is transmitted to the metal part. The central flange positions the seal for a perfect seal. In installations subject to vibration, the elastic part of the self-centering METAL-BUNA seal acts as a brake.
