    Straight thread to pex pipe connector
    My heating radiators have a reducer to 3/4" straight thread. For the 2 holes for venting and the plug I have the proper
    Fitting with a soft rubber or silicone ring that makes a seal.
    For the connections to pex pipe my plumber tried pipe dope/ teflon tape / pipe dope- Does not work, after a few heating cycles
    The connections start to leek. Is there a connector with a flat or grooved surface for an 0-ring available?
