  • Need to repair a broken Stainless 3-1/2in OD pipe. It is a steam pipe. Can you recommend a suitable high heat coupling?

    Any of the dresser couplings should be able to withstand steam as long as the temp is within the gaskets rating. for typical buna gaskets the max temp is 212F and for high temp gaskets it goes up to 1200F.

  • I have a 15.3" style 39-62 coupling and I'm looking for the size ranges that it can handle... I have a 15.45" outside diameter cast iron pipe that I need to connect to and I'm curious if the 15.3" can handle it

    No, 15.45 OD will not fit inside the 15.30 OD end of the coupling. Not enough tolerance.
