Metal jacket gaskets o�er an economical seal wheresealing faces are narrow.

www.robco.comGasket and RubberMetal Jacketed

Metal JacketSolid design - Solid resultsMetal jacket gaskets are the most basic type of semi-metallic gasket combining the high pressure suitability and blow-out resistance of metallic materials with the improved compressibility of soft materials.

Corrugated MetalGraphite CoatedCMGC gaskets featuring a corrugated metal core with a highly compressible graphite overlay, delivering a reliable gasket with the ability to seal at low bolt loads, conform to minor �ange imperfections and be manu-factured in virtually any con�guration.

Enviro�exSpiral Wound GasketSpiral Wound gaskets consist of metal strips spirally wound with a soft sealing �ller material. This sealing element is assembled with or without a metallic centering and/or inner ring(s). Made to �t #150 to #2500 pipe class �anges, they can be custom-made in various alloys and �llers to meet your requirement, custom sizes and application.

Maxipro�leSemi-Metallic GasketThe Maxipro�le is a composite gasket that utilizes a serrated metal core with a soft facing material. The metal core is machined on each contact face with concentric serrations providing high pressure areas and ensuring that the soft coating�ows into any imperfections in the �ange even at relatively low bolt loads.

Ring JointMetallic Ring Joint GasketMetallic ring joint gaskets are heavy duty, high-pressure gaskets largely used in o�shore petrochemical applications. These precision-engineered components designed for use in conjunc-tion with precision-machined �anges are manufactured in accordance with ASME B16.20 and API 6A.

A logical choice for standard �ange, heat exchanger, boiler and valve sealing applications.

Metal jacket gaskets o�er an economical seal wheresealing faces are narrow.

Metal JacketSolid design - Solid resultsMetal jacket gaskets are the most basic type of semi-metallic gasket combining the high pressure suitability and blow-out resistance of metallic materials with the improved compressibility of soft materials.

Corrugated MetalGraphite CoatedCMGC gaskets featuring a corrugated metal core with a highly compressible graphite overlay, delivering a reliable gasket with the ability to seal at low bolt loads, conform to minor �ange imperfections and be manu-factured in virtually any con�guration.

Enviro�exSpiral Wound GasketSpiral Wound gaskets consist of metal strips spirally wound with a soft sealing �ller material. This sealing element is assembled with or without a metallic centering and/or inner ring(s). Made to �t #150 to #2500 pipe class �anges, they can be custom-made in various alloys and �llers to meet your requirement, custom sizes and application.

Maxipro�leSemi-Metallic GasketThe Maxipro�le is a composite gasket that utilizes a serrated metal core with a soft facing material. The metal core is machined on each contact face with concentric serrations providing high pressure areas and ensuring that the soft coating�ows into any imperfections in the �ange even at relatively low bolt loads.

Ring JointMetallic Ring Joint GasketMetallic ring joint gaskets are heavy duty, high-pressure gaskets largely used in o�shore petrochemical applications. These precision-engineered components designed for use in conjunc-tion with precision-machined �anges are manufactured in accordance with ASME B16.20 and API 6A.

A logical choice for standard �ange, heat exchanger, boiler and valve sealing applications.
