Description
Designed to convert an imperial push-fit tube connection into an NPTF male threaded connection. This fitting provides a secure and efficient method of connecting tubing to threaded ports commonly found in pub, bar and beverage dispense equipment. Manufactured from rigid grey acetal copolymer and incorporating a nitrile O-ring seal, the adaptor creates an instant push-fit, leak-tight joint without the need for tools, hot works or sealing agents. The collet locking mechanism grips the pipe firmly without deforming or restricting flow, helping to maintain consistent system performance.
Fully demountable and reusable, the fitting allows quick system alterations and reduces downtime during servicing. Suitable for potable liquids, food grade applications and inert gases, it can be used on N2/CO2 and mixed gas dispense lines when installed in accordance with recognised industry practice. All John Guest fittings are manufactured and assembled in the UK.
