Frequently Asked Questions

Q: What makes G style air couplers different from other quick connect types? A: G style couplers are specifically designed for high-flow applications requiring over 60 SCFM. They feature larger internal passages and steel construction for maximum durability and airflow capacity compared to standard industrial or automotive styles. This design makes them ideal for professional pneumatic tools that need consistent high-volume air delivery without pressure drops.

Q: Will this coupler work with my existing air compressor setup? A: Yes, if your compressor has 1/2" NPT female threads and operates at or below 300 PSI. The G style design is compatible with matching G style plugs from Milton and other manufacturers using the same standard. Simply thread it onto your compressor outlet or air line and connect G style plugs for instant tool changes.

Q: How does this compare to standard 1/4 inch air couplers? A: This 1/2" G style coupler provides significantly higher airflow at 99 SCFM versus typical 1/4" couplers that max out around 20-30 SCFM. It's designed for heavy-duty tools that standard couplers cannot adequately supply. The larger bore size eliminates pressure restrictions that can cause tool performance issues with smaller couplers.

Q: What type of seal prevents air leaks in this coupler? A: The Milton 1815 uses a Buna-N rubber seal which provides excellent resistance to temperature extremes and maintains leak-free performance under high pressure and frequent connections and disconnections. This synthetic rubber material resists degradation from oils, fuels, and temperature cycling common in shop environments.
