The John Guest grey push‑fit acetal stem adaptor (BSP thread) provides a simple way to convert a John Guest push‑fit connection to a BSP threaded connection. Fast and easy to install, the push‑fit design delivers an instant, tool‑free connection with a reliable, leak‑tight seal—no hot works or sealing compounds required.

Its unique collet‑locking mechanism grips the pipe securely without causing deformation or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to enhance system performance and minimise downtime during maintenance.
