Style 167 Lock Couplings

When it comes to Dresser quality, there’s nothing unusual about the Style 167 Lock Coupling!

The Dresser 167 Lock Couplings actually “lock” the pipe and the coupling together to protect the line from pipe separation due to unusual movement. These couplings are for exceptional conditions such as ash handling and coal transmission lines, or unanchored high-pressure surface lines where added holding strength is desired.
