6/16/13: Bringing back this old thread... So we have a 1" NPS (straight thread) couplers that will fit directly up with an element. No more jimmy rigging an element into a NPT tapered threaded coupler.
Pricing will be $35/coupler. That includes the half 1" NPS coupler which will be sanitary TIG welded into any size kettle we offer. Lead times for these custom kettles will be 1-2 weeks.
For inquires or purchasing please email firstname.lastname@example.org
5/9/12: Well we will be rolling out a kettle with a custom 1" stainless coupler that is specially designed for an electric water heater element. The coupler is designed so the electric heater element will sit flush against the coupler engaging the o-ring (no more bottoming out on the NPT threads).
Our question is, who is interested? The additional coupler and welding will be a $30-$40 charge.
