Hose Couplings To Compressor - Seiko Seiki 55121
Specially developed snap on couplings are used to connect the draining and charging equipment hoses to the compressors service connections.
These snap on connections are designed as so called Schrader valves and are therefore connected in two stages:
1. Press the snap on coupling onto the compressor's service connection.
2. Turn the knob clockwise to open the valve and let the refrigerant pass through the connection.
Colour Marking of Components For R134A
Background
Components from A/C systems using R134a refrigerant must never, under any circumstances, be mixed with components from A/C systems using
R12 refrigerant.
Even very small quantities of the wrong refrigerant or compressor oil give rice to chemical reactions which will eventually ruin the entire A/C
system.
To prevent the wrong components from being fitted by mistake, the compressor and the expansion valve are unique to their particular A/C system
