The John Guest grey push-fit acetal tube-to-hose stem fitting enables the conversion of a push-fit connection to a hose-type threaded connection. Designed for ease of use, it offers quick installation and forms a secure push-fit connection with a leak-tight seal—no need for tools, hot works, or sealing compounds.

Its unique collet locking mechanism holds the pipe firmly in place without causing deformation or restricting flow. Corrosion-resistant and fully demountable, the fitting helps optimise system performance and reduce downtime during maintenance.

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