The two seals responsible for gas leaks in the SP2022:

The thin but larger-diameter orange gasket: Reference R406

What it does: It's the O-ring that seals the outside of the firing valve.

Position: It is placed around the thread of the B402 valve cap (on the right of the diagram). It prevents CO2 escaping through the threads when the valve is screwed into the magazine body.

The thicker but smaller yellow gasket: Reference R405

What it does: It's the drilling gasket for the CO2 cartridge (made of rigid polyurethane).

Location: Just above the B06 drilling block, at the very bottom of the magazine well. It surrounds the needle to crush the cartridge neck and prevent direct leakage when you strike it. It is accompanied by the small U01 bronze filter.

How to diagnose the problem using visual and auditory symptoms :

It's very easy to tell which gasket is faulty, because the sound and location of the leak immediately point to the culprit.

The piercing seal (thick yellow - R405)

This is the gasket that wears out fastest on CO2 chargers.

The direct symptom: As soon as you start to screw in the CO2 cartridge with the Allen key, you'll hear a loud, continuous hissing sound ("Pssssssss") escaping directly from the cartridge well (the large central opening).
The visual symptom: Sometimes, if the leak is very strong, white gel (due to the intense cold of the CO2) forms on the inside walls of the cartridge well.
The appearance of the defective gasket: If you look closely (or after disassembly), it is marked by a deep circular indentation, crushed, split or torn at the edges due to overtightening.

The percussion valve gasket (Orange fine - R406)

This gasket keeps the gas inside the firing mechanism.

The direct symptom: The cartridge pierces properly without noise in the center, but a slight hiss escapes from the rear of the magazine, just where the hammer of the replica hits the valve to fire.
Secondary symptom: Gas can also escape directly from the top of the magazine (the black bead exit seal) without you pulling the trigger.
The appearance of the defective seal: It's often dry, flattened (it's lost its well-rounded bead shape), or has micro-cuts caused by friction when the valve is screwed on.
