Install plumbing connections quickly and easily with the John Guest Speedfit 28mm Straight Coupler. This push-fit fitting allows for the secure connection of two equal pipe sizes. Installation is simple: push the fitting fully onto the pipe and twist the plastic nut clockwise to lock. Demounting is just as straightforward – unlock the nut, push the collet towards the fitting body, and pull the pipe to release. The Speedfit system offers a faster installation (up to 40% quicker than traditional methods) and is ideal for confined spaces as it requires no hot works or tools. Features a safe, flame-free installation process with no need for glue or flux. The Grip & Seal collet, equipped with stainless steel teeth and a main O-ring seal, ensures a secure connection. The Twist & Lock mechanism further enhances security and compression. Made from durable, non-toxic plastic and stainless steel, this fitting resists corrosion and scale build-up. Compatible with Speedfit PEX and polybutylene plastic pipes (inserts required) and copper pipes. Suitable for both hot and cold water and central heating systems.
