Quickly and easily increase the diameter of a John Guest push-fit fitting with this grey acetal enlarger. Designed to expand an existing push-fit connection port, this fitting offers a fast and straightforward installation, creating a secure joint and a leak-tight seal—without the need for tools, heat, or sealing agents.

Its precision collet locking system ensures the pipe is held firmly without distortion or restricting flow. These fittings are corrosion-resistant and fully demountable, helping to maintain system performance and minimise downtime during servicing.

Manufactured from robust grey acetal copolymer, the enlarger is suitable for foodstuffs, potable liquids, and inert gases. In compliance with the British Beer & Pub Association Code of Practice, it can also be used for N₂/CO₂ and mixed gas dispense lines, as well as air, pneumatic, and vacuum applications. All John Guest fittings are manufactured and assembled in the UK.
