ZAGO Manufacturing Company, Inc.
Sealing Screws In Petrochemical Industries on pipes and connections and for equipment building purposes. Sealing screws are cylindrical fasteners. They're made of metal and have a metallic head that is custom-grooved. Sealing fasteners include sealing screws and sealing bolts, and can be tailored to fit a threaded opening. Depending on the type of head, sealing screws get tightened by torque exerted with a suitable wrench or screwdriver. Sealing screws and bolts are engineered with an O-ring that forms an air-tight seal, the function of which... (read more)Browse Screws Datasheets for ZAGO Manufacturing Company, Inc. -
ZAGO Manufacturing Company, Inc.
Sealing Screw or Sealant? . A seal screw is machined with a groove under the head of the screw that fits a rubber O-ring. Once the seal screw is torqued, the rubber O-ring expands to create an impenetrable 360? seal. This seal prevents contaminants, like oils, liquids, gas, moisture, and precipitation from seeping into equipment and damaging it or out and potentially harming the environment. If you are designing military and aerospace equipment, the undercut O-ring groove system is best. Unlike sealants, the undercut O-ring...
