Abstract
An aspect of the invention provides a kit including: four fittings and a length of HVAC/R line set. Each of the four fittings include a fitting body and a nut. The fitting body defines: a swivel end and a second end. The swivel end includes: a sealing surface; a radially outer distal stop shoulder; a radially outer medial stop shoulder; and a radially outer neck having an outer diameter less than each of the radially outer distal stop shoulder and the radially outer medial stop shoulder. The nut includes a threaded region and a radially inner stop shoulder rotatably retained within the radially outer neck of the swivel end of the fitting body.
Claims16
A fitting comprising:
- a fitting body defining:
- a swivel end comprising:
- a sealing surface;
- a radially outer distal stop shoulder;
- a radially outer medial stop shoulder;
- and
- a radially outer neck having an outer diameter less than each of the radially outer distal stop shoulder and the radially outer medial stop shoulder;
- and
- a compression end comprising:
- a nipple;
- and
- a threaded region;
- a swivel nut comprising:
- a threaded region;
- and
- a radially inner stop shoulder rotatably retained within the radially outer neck of the swivel end of the fitting body;
- a ferrule adapted and configured for placement radially over the nipple to engage a length of line set between the ferrule and nipple;
- and
- a compression nut adapted and configure to thread onto the threaded region of the compression end of the fitting body and compress the ferrule.
A kit comprising:
- four fittings, each of the four fittings comprising:
- a fitting body defining:
- a swivel end comprising:
- a sealing surface;
- a radially outer distal stop shoulder;
- a radially outer medial stop shoulder;
- and
- a radially outer neck having an outer diameter less than each of the radially outer distal stop shoulder and the radially outer medial stop shoulder;
- and
- a second end;
- and
- a nut comprising:
- a threaded region;
- and
- a radially inner stop shoulder rotatably retained within the radially outer neck of the swivel end of the fitting body;
- and
- a length of HVAC/R line set.
A system comprising:
- a compressor;
- an evaporator coil;
- and
- a refrigerant line set coupled between the compressor and the evaporator coil to form a fluid circuit between the compressor and the evaporator coil;
- wherein the refrigerant line set is coupled to the compressor and the evaporator coil by a set of four fittings, each of the four fittings comprising:
- a fitting body defining:
- a swivel end comprising:
- a sealing surface;
- a radially outer distal stop shoulder;
- a radially outer medial stop shoulder;
- and
- a radially outer neck having an outer diameter less than each of the radially outer distal stop shoulder and the radially outer medial stop shoulder;
- and
- a second end;
- and
- a nut comprising:
- a threaded region;
- and
- a radially inner stop shoulder rotatably retained within the radially outer neck of the swivel end of the fitting body.
