The John Guest grey push-fit acetal tube-to-hose stem adaptor is designed to convert a standard push-fit connection into a hose-type threaded connection. Installation is quick and straightforward, with push-fit technology providing a secure connection and a leak-tight seal—eliminating the need for tools, heat, or sealing agents.

Its precision collet locking system ensures the pipe is held firmly without distortion or restricting flow. These fittings are corrosion-resistant and fully demountable, helping to maintain system performance and minimise downtime during servicing.

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