The John Guest Metric‑to‑Imperial push‑fit Stem‑to‑Stem Adaptor is designed to convert a standard push‑fit connection into a reduced stem connection. Installation is quick and straightforward—John Guest push‑fit technology provides an instant, secure connection and a leak‑tight seal without the need for tools, heat, or sealing compounds.

Engineered to a high standard, the adaptor is suitable for foodstuffs, potable liquids, and inert gases. In line with the British Beer & Pub Association Code of Practice, it is also approved for use with 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.
