The DAVANT Swivel Elbow in a mechanical waste system allows for a change of direction in the piping system, such as in the installation of drainage or wastewater systems.. It is designed with a swivel joint that enables it to rotate, providing flexibility in the installation process. The swivel elbow typically consists of ABS or PVC pipes and fittings with rubber seals that are inserted into the joints and tightened with stainless steel clamps to create a secure and leak-free connection. Swivel elbows are available in various angles, typically 45 and 90 degrees, to accommodate different plumbing configurations. The mechanical joint and swivel feature allow for a more flexible and easier installation process compared to traditional solvent welding, making it a popular choice for residential and commercial plumbing applications.
