A flexible heater connector comprising:
- a hose;
- a nut having a female tapered thread to engage a male tapered thread associated with a heater;
- a fitting structure including a first portion to mechanically engage an inner wall of the hose, and a second portion mechanically coupled to the nut;
- a hose crimp for tightening the hose onto the fitting structure;
- an o-ring arranged between the nut and the second portion of the fitting structure;
- and
- a gasket arranged around the first portion of the fitting structure for mechanical separation between an end of the nut and an end of the hose facing the end of the nut to prevent direct contact between the hose crimp or the end of the hose and the nut;
- wherein the nut is a swivel nut capable of rotating around a longitudinal axis of the nut.
