Fittings are 7/16′′ Flare x 14MM Hose for Automotive R-134a. R134a Anti-Blowback Adapter – 1/2′′ ACME Male x 1/2′′ ACME female: This adapter helps to prevent refrigerant loss from the yellow hose when disconnecting from the R134a tank.
What thread is R134?
Application: The can valve fits EASILY for R-134a cans with 7/16-28 UNF threads , the other end of the R134a can valve connects with 1/4 SAE female fittings a/c charge hose.
What size are r134a fittings?
Fittings are 7/16′′ Flare x 14MM Hose for Automotive R-134a. There is a lot of differences between the R12 and the R134a fittings, you can’t mistake them.
What size are refrigerant hose fittings?
Connection sizes are 1/4′′, 1/4′′-3/8′′, and 3/8′′ . Hose colors are Black, Black/Red/Yellow/Blue, Blue, Red, Red/Blue/Yellow, Red/Yellow/Blue, Yellow, and Yellow/Blue/Red.
What size is the low pressure AC port?
The low side port will have a 13 mm quick-disconnect valve fitting with a black or blue cap on vehicles with R134a Freon, or a 7/16-inch threaded valve fitting on vehicles with R12 Freon.
What size is R22 fitting?
Newer R410A Ductless Mini Split Systems are usually equipped with a different charging port size to avoid charging of wrong refrigerant into the system (ie R22). This new port size is 5/16′′ SAE and some gauge sets carry 1/4′′ SAE connectors.
How are AC fittings measured?
ACR (Air Conditioning and Refrigeration) tubing is charged with nitrogen and sealed. ... Refrigeration tubing is measured by it’s outside diameter or O.D.: 1⁄4, 1⁄2, 5/8, 3⁄4, 7/8, 1-1/8, 1-3/8, 1-5/8, etc. Plumbing tubing is measured by it’s inside diameter or I.D. : 1/8, 1⁄4, 1⁄2, 3⁄4, 1, 1-1/4, 1-1/2, 1-3/4,etc.
What size is R12 fitting?
The low-side R12 port is always 1/4′′ male flare thread . While the high-side is usually the same size as the low, in certain applications it could be a smaller 3/16′′ male flare.
What is an Acme fitting?
An ACME fitting is a piece of pipe that either connects one or two pieces of pipe together . Continental NH3 carries various types of ACME fittings, such as couplings and adapters. Our fittings are manufactured specifically for the agricultural industry and used for Anhydrous Ammonia.
When a leak is found in an automotive air conditioning system?
If the detector indicates a leak, the evaporator or the line connecons to the evaporator are leaking. After a system has been opened for repair, the system should be properly leak tested before charging with refrigerant. The system should hold a deep vacuum (27 in HG. or more) for at least one minute before charging.
What size is #6 hose?

What is a AC manifold?
A manifold gauge is a pressure-checking system . They are one of the most basic HVAC tools, and can be used as both a diagnostic and service tool. ... When used as a service tool, a manifold gauge can be used to release moisture and sludge, and remove contaminated refrigerants from the system.
Can you use an fittings for air conditioning?
thanks. There are braided-type hoses and fittings made for AC use, but the usual stuff you use for oil hoses, etc. will not work. Refrigerant molecules (especially R-134a) will seep right through most rubber hoses and the AN flare fittings as well.
Do you charge AC system on high or low side?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side . When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
What color is the low side of an AC system?
Red hose goes to the high pressure side, blue goes to the low pressure side and yellow hooks to Freon source, can, etc.
