The McAlpine T20L is a 135-degree bend fitting that is part of the Surefit range of push-fit plumbing fittings and pipes made by McAlpine. The T20L is designed to connect two 1 1/2-inch pipes at a 135-degree angle, without the need for special tools or adhesives. The T20L bend fitting features a push-fit connection on both ends, which allows for quick and easy installation. The connector is made of durable plastic, which is lightweight and corrosion-resistant, and is designed to create a watertight seal between the two pipes. It's important to note that the T20L bend fitting is designed specifically for use with the McAlpine Surefit system, and may not be compatible with other types of plumbing systems or fittings. Additionally, it's important to ensure that the T20L bend fitting is used in accordance with any local plumbing codes and regulations to ensure proper installation and safety.
