Fix a Leaky CO2 Airsoft Pistol Seal

If you have any experience with Airsoft, you probably know that CO2 pistols like to leak.

There are two types of leaks: Valve leaks and seal leaks.

If gas is coming out the barrel, that is a valve leak and a lot harder to fix.

If gas is coming out the seal around the tip of the cartridge, that is a seal leak.
This is how to fix seal leaks.

Step 1: Materials

You need:

• The leaky gun in question
• Full cartridge
• Teflon plumbers tape, available at any hardware store that is worth shopping at.
• Silicone spray lubricant or Paintball marker oil. Do not use any other type of oil, it will freeze and damage the seal even more.
