Abstract
A diverter for redirecting drilling fluid in oilfield applications includes a support housing and a diverter body disposed therein. A lateral opening defined in the diverter body permits fluid communication between an interior passage of the diverter body and a lateral now outlet defined by the support housing. A pair of flow-line seals disposed radially between the support housing and the diverter body includes a flow-line seal disposed on axially upper and lower sides of the lateral flow outlet. The flow-line seals include a pair of substantially rigid support rings and first and second sealing bodies adhered thereto. The first sealing body is affixed to an inner diameter wall of the first and second support rings and extends to axially upper and lower walls of the support rings. The second sealing body is bonded axially between the support rings.
