Engineering Excellence
Precision Machining
Every Vertex coupling is manufactured to exacting tolerances using advanced CNC machining processes. The result is a component with perfectly concentric bore dimensions, smooth internal surfaces that minimize turbulence, and thread profiles that ensure optimal sealing performance.
Material Superiority
Brass offers the ideal combination of properties for pneumatic fittings: excellent machinability for precision threads, natural lubricity for easy assembly, superior corrosion resistance in humid environments, and the strength to withstand system pressures without deformation.
Leak-Free Performance
The 7.9mm internal diameter is precisely sized to create an interference fit with standard 5/16″ pneumatic hose. When secured with appropriate hose clamps, this coupling creates a gas-tight seal that maintains system efficiency and prevents costly air leaks.
Installation Guidelines
- Select pneumatic hose with 5/16″ (7.9mm) internal diameter
- Cut hose end square using a sharp blade for clean insertion
- Lubricate tailpiece lightly with soapy water if needed for easier assembly
- Push hose firmly onto tailpiece until fully seated
- Secure with appropriate hose clamp positioned 5-10mm from hose end
- Tighten clamp to manufacturer's specification—avoid over-tightening
- Pressure test connection before putting system into service
