A wear-resistant sealing system for introducing fracturing fluids to a wellhead comprising a tubular connector having a retaining shoulder and bridging a flange interface created between a frachead and a lower tubular structure. The tubular connector has upper and lower sealing elements above and below the flange interface and forms a contiguous bore for fluid communication of the fracturing fluids from the frachead to the lower tubular structure and wellhead.

Système d'obturation résistant à l'usure permettant d'introduire des liquides de fracturation dans une tête de puits pourvu d'un raccord tubulaire muni d'un épaulement de retenue et surplombant une interface à bride formée entre une tête de fracturation et une structure tubulaire inférieure. Le raccord tubulaire comporte des éléments d'obturation supérieur et inférieur aménagés au-dessus et en dessous de l'interface à bride. Il forme un alésage contigu qui permet d'acheminer le liquide de fracturation de la tête de fracturation vers la structure tubulaire inférieure et la tête de puits.
