The McAlpine T12S is a reducer fitting that connects a 1 1/2-inch pipe to a 1 1/4-inch pipe in a Surefit plumbing system. Surefit is a range of push-fit plumbing fittings and pipes made by McAlpine that are designed for quick and easy installation without the need for special tools or adhesives. The T12S reducer is made of durable plastic and features a push-fit connection on both ends, allowing for easy installation and removal. It is designed to be used specifically with Surefit fittings and pipes, so it may not be compatible with other plumbing systems. It's important to note that the T12S reducer is not designed for use with high-pressure or hot water systems, and should only be used in applications where the water pressure and temperature are within the specified limits for the Surefit system.
