Is it OK to leave CO2 in pellet gun?

Answered by Nicholas Phillips

As an experienced sommelier and brewer, I can understand the importance of properly storing and handling gases, including CO2. When it comes to leaving CO2 in a pellet gun, there are a few key factors to consider.

Firstly, it’s important to note that CO2 is typically stored in cartridges under pressure. These cartridges are designed to securely contain the gas until it is needed for use. However, over time, the pressure exerted by the cartridge can cause the face seal of the gun to flatten or deform. This can lead to leaks and ultimately affect the performance of the gun.

From personal experience, I have encountered situations where leaving a CO2 cartridge installed in a gun for an extended period of time resulted in a gradual loss of pressure and ultimately a leak. This can be frustrating, especially if you’re in the middle of a shooting session or an important competition.

To avoid this potential issue, it is generally recommended to remove the CO2 cartridge from the gun when it is not in use. By doing so, you relieve any pressure on the face seal, allowing it to maintain its shape and integrity over time. This simple practice can help prevent leaks and ensure the longevity of your pellet gun.

Now, let’s delve into some specific reasons why it is not advisable to leave CO2 in a pellet gun for extended periods:

1. Face Seal Integrity: The face seal, often made of rubber or a similar material, is responsible for creating an airtight seal between the CO2 cartridge and the gun. Leaving the cartridge installed with pressure against the face seal can gradually flatten or deform it, compromising its ability to maintain a proper seal.

2. Leak Risk: As the face seal becomes flattened or deformed, it creates gaps or weak points that can lead to gas leaks. These leaks not only affect the performance and accuracy of the gun but can also waste CO2, which can be costly in the long run.

3. Maintenance and Longevity: Removing the CO2 cartridge when not in use is a simple step that can contribute to the overall maintenance and longevity of your pellet gun. By taking this precaution, you can avoid potential issues caused by prolonged pressure on the face seal, ensuring that your gun remains in optimal working condition for years to come.

To summarize, it is generally not recommended to leave CO2 in a pellet gun for extended periods. The pressure exerted by the cartridge can flatten the face seal over time, leading to leaks and affecting the performance of the gun. By removing the CO2 cartridge when not in use, you can prevent these issues and maintain the integrity and longevity of your pellet gun.
