‘Dry’ embedded O-ring sealing fastener technology (with optional thread locking) and ‘wet’ liquid adhesive thread locking, have been the choices for pump manufacturers and users for more than half a century – wherever secure sealing under pressure as well as fastening has been required. Fluid/gas fastener leakage originating from within as well as preventing seepage from external contaminants, requires a reliable, adjustable sealing barrier – especially when field servicing and employee health are considered.
