Coliter ® Quick-Connect Nut, Brass, for Corrugated Gas Hose to 1/2" BSP Connection
Quick-Connect Nut – Brass Compression Fitting for Secure Attachment of Corrugated Gas Hoses
The Coliter® Quick-Connect Nut is a brass compression nut designed to securely fasten stainless steel pliable corrugated gas hoses (such as the GZ6001 series) to threaded ports on valves, regulators, or appliances in natural gas and LPG systems. It works in conjunction with a ferrule or sleeve to create a leak-tight, vibration-resistant connection when tightened onto a male ISO 228 (BSP parallel) thread—typically 1/2" F. Available in multiple sizes to match common hose outer diameters including Ø13.5×1/2" F, Ø16×1/2" F, Ø18.5×1/2" F, Ø24.8×1/2" F, and Ø31.8×1/2" F, this nut enables rapid, tool-assisted installation without soldering or threading. Made from high-quality forged brass, it ensures durability, corrosion resistance, and reliable performance in residential and commercial gas piping applications.
