We can only ensure the performance of D-Nail Heaters when paired with D-Nail Controllers.
Other brands are wired to be compatible to D-Nail tech, many work but we cannot warranty cross-brand use.
If you are trying to assemble any heater with a quartz nail, and it either does not fit easily or appears significantly loose, contact us before proceeding.
There are too many steps involved in turning raw heating elements and raw tubing into finished and 'perfectly' matched parts to always get it right.
We are using custom molds and strictly quality control procedures to attempt to standardize these as much as possible.
