Shows Nitrogen CGA-677 better for filling PCP Airguns than CGA-580 tanks

Filling your PCP airgun with Nitrogen is another option to consider. The air from a Nitrogen tank is cleaner and dryer than the air generated by cheap Chinese compressors. This can be beneficial for protecting the internal parts of your airgun, such as the regulator. However, it’s important to understand the differences between CGA-580 and CGA-677 tanks, as well as the pros and cons of using Nitrogen to fill your PCP airgun.

When it comes to CGA-580 tanks, it’s important to note that these tanks are only filled to 2,015 psi, and they are not a viable choice for filling or tethering PCP airguns. The CGA-580 valve is rated to handle 3,660 psi, but the rated safety on the valve is 3,500 psi.

On the other hand, CGA-677 tanks are becoming increasingly popular for filling PCP airguns and small carbon fiber tanks. These tanks are equipped with a CGA-677 valve, which is designed to provide a higher volume of air at a higher pressure. With a fill pressure of around 6,000 psi, this is especially beneficial for those who frequently fill their airguns or have multiple airguns to fill.

It’s also worth mentioning that if you’re unsure of which tank and its fill pressure you have, you can look at the valve installed on the tank. It will be marked with CGA-580 or CGA-677 depending on which tank it is installed on. has fittings for both CGA-580 and CGA-677 tanks, so you can use whichever type of tank you prefer.

Before investing in a Nitrogen tank, it’s important to consider availability and cost. It’s worth shopping around to find the best option that fits your needs and budget. However, there are negatives to consider when filling PCP airguns with Nitrogen tanks. The buy-in cost and cost to refill can be high, and the weight of the steel Nitrogen tanks makes them hard to transport. Additionally, you’ll need to refill them when they are down to 3000 psi (unless tethering to an airgun) or using a booster pump.

In conclusion, while Nitrogen is a great option for filling PCP airguns, as it offers clean and dry air, it’s important to consider the costs and logistics of using Nitrogen tanks. 

CGA-677 tanks are a viable option for filling PCP airguns, as they offer a higher fill pressure of 6,000 psi. However, it’s important to note that CGA-580 tanks are not a viable option for filling or tethering PCP airguns due to the low fill pressure of 2,015 psi.

In summary, when it comes to filling PCP airguns, Nitrogen tanks (CGA-677) are a great option, offering a higher flow rate, faster filling times, and a higher fill pressure of 6,000 psi. CGA-580 tanks are not a viable option for filling or tethering PCP airguns due to the low fill pressure of 2,015 psi.
