Quickly and securely converts a superseal imperial connection to a metric connection

John Guest push-fit straight connector metric to imperial (superseal) fitting for converting LLDPE tubing or soft metal tubing and polished metal tubing from imperial sizing to metric. Fast and simple to install, John Guest push-fit fittings create an instant push-fit connection and leak tight seal without the need for tools, hot works or sealing agents.

The unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow. The superseal provides extra grip and the hand-operated nut and wedge plastic washer applies pressure on the collet and double O-Rings, ensuring the stainless-steel teeth bite firmly onto the pipe, while compressing the O-Rings to enhance the seal.

Fittings are corrosion resistant and fully demountable, improving system performance and reducing system downtime during maintenance. Manufactured in tough engineered plastic, the fitting is suitable for potable liquids and foodstuff. All John Guest fittings are manufactured and assembled in the UK.
