The John Guest grey push-fit acetal end stop fitting is designed to quickly and safely seal off pipework termination points, either temporarily or permanently. Easy to install, it provides an instant push-fit connection and a leak-tight seal—without the need for tools, hot works, or sealing compounds.

Its unique collet locking mechanism securely holds the pipe in place without causing deformation or restricting flow. The fitting is corrosion resistant and fully demountable, helping to enhance system performance and reduce maintenance downtime.

Manufactured from grey push-fit acetal copolymer, it is suitable for foodstuffs, potable liquids, and inert gases. In accordance with the British Beer & Pub Association Code of Practice, it can also be used with N₂/CO₂ and mixed gas dispense lines, as well as in air, pneumatic, and vacuum applications.

All John Guest fittings are proudly manufactured and assembled in the UK.
