Refrigerant fittings are a broad topic encompassing plenty of different fittings for a variety of cooling appliances. So, how do you know which fitting you need? Thankfully, you personally do not have to know that; your HVAC technician does. Still, it helps to take a look at the different fittings that exist and learn to recognize when the right fitting is used versus the wrong fitting and how it may be adapted to be the right fitting with the right cooling appliance. Here are just some categories of fittings for specific uses.
Household Refrigerator Fittings
These fittings are usually aluminum, because aluminum will not rust or corrode, and they are lighter in weight and cheaper to make. They are the ideal fitting for appliance manufacturers so they can produce refrigerators that homeowners can afford. These refrigerator parts are also some of the smaller fittings on the market because everything else is made for mostly larger appliances.
Commercial Refrigerator or Freezer Fittings
The giant "walk-ins" in restaurants and grocery store coolers are where these fittings can be found. They may resemble similar parts to those used in home refrigerators, with some obvious differences in sizes and connections. Commercial refrigerator parts, like refrigerant fittings, are quite a bit larger than their residential counterparts, which only makes sense considering the size of the refrigeration units into which these fittings are installed. To learn more about refrigerator parts like these, contact a supplier.
Air Conditioning Fittings
Air conditioning fittings are rather peculiar looking. They do not resemble anything used in most other refrigeration appliances, which is probably most helpful when one needs to identify a fitting and one does not know to what appliance this fitting belongs. More often than not, these fittings are steel in order to withstand outside elements and last longer under pressure and temperature swings.
RVs are essentially houses on wheels. You will have both air conditioning and a working refrigerator in your RV. You may also have the means to cool water from your clean reserve tank for your cold water taps in the RV. (It just depends on how "luxury" your RV is.) Ergo, it should not surprise you that your RV has several different refrigerant fittings, all of which install behind or under something in your RV.
More and more city transport and shuttle buses are switching to propane, and propane is compressed liquid gas. This compressed liquid gas is freezing cold, and it cannot be channeled properly into the specialty engine without the right fittings and hoses.
