John Guest grey push-fit acetal tube‑to‑hose stem fittings allow you to convert a standard John Guest push‑fit connection into a hose‑thread style connection. Designed for quick, hassle‑free installation, these fittings create an instant, reliable seal without the need for tools, heat, or sealing compounds.

Their unique collet‑locking mechanism grips the pipe securely without causing deformation or restricting flow. Made from corrosion‑resistant materials and fully demountable, these fittings help maintain system performance and minimise downtime during servicing or maintenance.
