The John Guest grey push-fit acetal straight adaptor with BSPT thread converts metric pipe to an imperial BSPT threaded connection for easy attachment to a fitting, fixture, or appliance. Installation is quick and simple using push-fit technology—no tools, hot works, or sealing agents required. Each fitting provides an instant, leak-tight seal for dependable performance.

Its unique collet locking design secures the pipe firmly without causing deformation or restricting flow. Corrosion-resistant and fully demountable, this fitting improves system efficiency and reduces downtime during maintenance.

Made from durable grey acetal copolymer, the adaptor is suitable for food-grade applications, potable liquids, and inert gases. In line with the British Beer & Pub Association Code of Practice, it can also be used with N₂/CO₂ mixed gas dispense lines, as well as air, pneumatic, and vacuum systems. All John Guest fittings are manufactured and assembled in the UK.
