John Guest Speedfit products utilize push-fit and multi-seal technology for reliable, leak-proof connections. Installation and de-mounting are simple and tool-free, facilitating work in tight spaces and easy adjustments. The range includes plastic, brass, and chrome fittings, tap connectors, valves, and flexi hoses, ideal for completing plumbing and heating jobs efficiently. When paired with plastic push-fit pipe, these components create a flexible plumbing and heating system. All products are WRAS accredited and suitable for plastic or copper pipe. To install, push the fitting fully onto the pipe and twist the plastic nut clockwise to lock. For de-mounting, unlock the nut, push the collet towards the fitting body, and pull the pipe to release. The design ensures an easier working environment in confined spaces and eliminates the need for hot works. * Suitable for hot and cold water services, NOT suitable for central heating systems * BS EN 7291 parts 1, 2, 3 and S, WRAS approved * Secure and easy demounting without tools * 50 year guarantee * Minimum operating temperature - 20 degC * Maximum operating temperature - 65 degC * Maximum operating pressure at minimum temperature - 12 BAR * Maximum operating pressure at maximum temperature - 3 BAR
