The John Guest push‑fit polypropylene Speedfit male shut‑off valve (NPTF thread) provides a quick, reliable way to isolate the supply to a fixture or appliance. Its push‑fit design delivers an instant, leak‑tight seal without the need for tools, heat, or sealing compounds.

A precision collet locking mechanism grips the pipe securely without distortion or restricting flow, while the corrosion‑resistant, fully demountable construction enhances system performance and makes maintenance faster and more efficient.
