With a 20 oz canister, A/C Pro R134a is capable of filling most vehicle A/C systems completely. This means you can enjoy the cool comfort of your A/C system for longer periods without worrying about running out of refrigerant.

To make the recharging process even easier, this product comes with a convenient charging hose and digital gauge. The hose allows for easy attachment to your vehicle's A/C system, while the digital gauge provides accurate pressure readings to ensure proper charging.

When selecting a fire hose pipe coupling, it is important to consider factors such as the size and type of hose being used, the pressure at which the system will operate, and the specific requirements of the firefighting operation. Choosing the right coupling ensures a secure and reliable connection that can withstand the demands of firefighting operations.
