Coupling & Repair

Style 711 Bolted Couplings

Dresser recently introduced a new-and-improved design of the Style 711 seal & restraining coupling product line. This new design meets all requirements of the Category 1 Code of Federal Regulations. 

The combination of components on the compression end(s) of the Style 711 product design results in an air-tight pressure seal, while the metallic gripping mechanism locks the pipe against pull-out, providing a complete seal and restraining connection.
