Brass air hose couplings have several advantages:

Durability: Brass is a durable material that is resistant to wear and corrosion, making it ideal for use in air hose couplings. This means that brass air hose couplings are less likely to break, rust or wear out, even with regular use.

Temperature Resistance: Brass air hose couplings are able to withstand high temperatures, making them suitable for use in industrial settings where high temperatures may be present.

Ease of Use: Brass air hose couplings are easy to connect and disconnect, making them a popular choice for quick connections.

Versatility: Brass air hose couplings are compatible with a wide range of hoses, making them versatile and adaptable to different types of applications.

Wide Availability: Brass air hose couplings are widely available, making them easy to replace if they become damaged or worn.

Non-magnetic: Brass is a non-magnetic material, which means it won't interfere with sensitive electronic equipment.
