The John Guest push‑fit polypropylene straight adaptor with NPTF thread allows metric pipe or tube to be connected to an imperial NPTF threaded fitting, fixture, or appliance. Installation is quick and straightforward—the push‑fit design provides an instant, secure connection with a leak‑tight seal, all without tools, heat, or sealing compounds.

Its precision‑engineered collet locking system grips the pipe firmly without deforming it or restricting flow. Made from corrosion‑resistant materials, the fitting is fully demountable, helping maintain system performance and reducing downtime during maintenance.
