John Guest white push‑fit acetal straight adaptor with NPTF thread designed to convert metric pipe to an imperial NPTF threaded connection for attachment to fittings, fixtures, or appliances. The push‑fit design enables quick, tool‑free installation, forming an instant, leak‑tight seal without the need for hot works or sealing agents.

Its precision collet locking mechanism securely grips the pipe without deforming it or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to maintain system performance and reduce downtime during maintenance.

Manufactured from white push‑fit acetal copolymer with EPDM O‑Rings, this adaptor is suitable for potable water, intermittent hot‑water applications (up to 65°C), and water treatment or purification systems. All John Guest fittings are manufactured and assembled in the UK.
