The John Guest grey push‑fit acetal straight adaptor (NPTF thread) allows metric pipe to be connected to an imperial NPTF threaded fitting, fixture, or appliance. Designed for quick installation, John Guest push‑fit technology provides an instant, tool‑free connection with a dependable, leak‑tight seal—eliminating the need for hot works or sealing agents.

Its precision‑engineered collet locking system secures the pipe firmly without deforming it or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to maintain system performance and minimise downtime during maintenance.
