The John Guest grey push‑fit acetal straight adaptor (BSW thread) allows you to connect metric pipework to an imperial BSW‑threaded nipple for easy attachment to fittings, fixtures, or appliances. Designed for quick installation, John Guest push‑fit technology provides an instant, secure, leak‑tight seal without the need for tools, heat, or sealing compounds.

Its collet‑locking mechanism grips the pipe firmly without causing deformation or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping maintain system performance and reducing downtime during servicing or modifications.
