KF Range · Professional Air Line Fittings
Precision-Engineered Quick-Release Coupling for 6mm Air Hose
Designed for professionals who demand zero-compromise airflow, instant tool changes, and leak-free performance across every shift.
Overview
The KF Coupling 6mm Hose Tail is a workshop-grade quick-release fitting built for compressed air systems that cannot afford downtime. Machined from high-tensile steel and rated to a maximum working pressure of 35 bar (508 PSI), this coupling delivers a secure, leak-resistant seal every time — whether you're swapping pneumatic tools on a busy garage floor or maintaining an industrial air line in a manufacturing facility.
The hose tail design creates a positive mechanical grip on 6mm internal-diameter flexible air hose, eliminating the micro-leaks that rob your system of pressure and efficiency. With a nominal bore of 7.6mm and a peak flow rate of 2,100 litres per minute at 6 bar, airflow is never the bottleneck.
Key Features
Instant Connection
KF-standard quick-release mechanism connects and disconnects in under a second — no tools, no thread tape, no delay.
High-Pressure Rated
Certified to 35 bar / 508 PSI maximum working pressure, covering the full range of professional compressor outputs.
Steel Durability
Heavy-duty steel body resists impact, corrosion, and workshop abuse — built to outlast the hoses it connects.
Leak-Resistant Seal
Precision-machined seating surfaces and a positive-lock collar ensure an airtight connection under sustained pressure.
Wide Temperature Range
Operates reliably from −40°C to +100°C — suitable for cold-store environments through to high-heat industrial settings.
6mm Hose Compatibility
Engineered specifically for 6mm internal-diameter flexible air hose — the most common bore in light-trade and workshop systems.
