Abstract
A fitting for a heat pump having at least one heat exchanger includes a first fitting element configured for connection with a tubing portion of the heat exchanger and a second fitting element removably connectable to the first fitting element and configured for connection with a tubing portion of the heat exchanger. A non-conductive element is disposed between at least a portion of the first fitting element and at least a portion of the second fitting element such that, when connected, the non-conducting element deforms between the first fitting element and the second fitting element to electrically isolate the second fitting element from the first fitting element.

A fitting for a heat pump having at least one heat exchanger, the fitting comprising:
- a first fitting element configured for connection with a tubing portion of the heat exchanger;
- a second fitting element removably connectable to the first fitting element and configured for connection With a tubing portion of the heat exchanger;
- and
- a non-conductive element disposed between at least a portion of the first fitting element and at least a portion of the second fitting element such that, when connected, the non-conducting element deforms between the first fitting element and the second fitting element to electrically isolate the second fitting element from the first fitting element.
A fitting comprising,
- a first fitting element configured for connection with a first tubing portion;
- a second fitting element removably connectable to the first fitting element and configured for connection with a second tubing portion;
- and
- a non-conductive element disposed between at least a portion of the first fitting element and at least a portion of the second fitting element such that, when connected, the non-conducting element deforms between the first fitting element and the second fitting element to electrically isolate the second fitting element from the first fitting element.
A method for electrically isolating a first portion of a fitting from a second portion of a fitting configured for use on a heat pump, the method comprising:
- positioning a nut over a tubing portion, such that the tubing portion extends through the nut;
- securing a second fitting element to a terminal end of the tubing portion, such that at least a portion of the second fitting element is received within the nut;
- securing a non-conducting element around the second fitting element;
- connecting a first fitting element with the nut, such that the non-conducting element is deformed between the first fitting element and the nut,
- wherein the non-conducting element provides an electrical isolation gap to electrically isolate the second fitting element from the first fitting element and the nut.
