WEC's Innovative Alternative to Screw Plug Heaters: "AB" Family of Flanged Immersion Heaters


In a few easy steps, Warren Electric Corporation’s “AB” adapter converts your screw plug heater application into a flanged heater application.  A screw plug heater is often difficult to replace because you have to use a large wrench where, often times, pipes and fixtures get in the way.
        This makes changing a screw plug heater frustrating, time consuming, and


sometimes impossible!  The solution is to switch to a flanged heater by using WEC’s “AB” series of flanged heaters and adapters.
        Future replacement of the flanged heater can be done in a jiffy using a 7/16” socket and a lot less effort.
Here’s How It’s Done
        Our fixed threaded-type adapter has a flange at one end and is threaded at the other.  Just remove the existing screw plug heater, screw in the adapter, insert the “AB” flanged heater, then simply tighten the bolts

with a ratchet or box wrench.  For new tank designs, use our square cut tank adapter  It welds directly to a tank and accommodates either our “AB” or ANSI flanged heaters.  It also has the swiveling option that rotates a full 360° allowing you to position the conduit opening to wherever you need it.
        We also devised other clever adapters that make flanged mounting an excellent alternative to screw plug process heaters.
