What is a hub less fitting?

A hubless fitting is a type of pipe fitting that does not have a traditional hub or socket for connecting pipes. Instead, it relies on a compression or mechanical method to secure the pipes together, offering a more streamlined design. This type of fitting is often used in applications where space is limited or where a cleaner aesthetic is desired. Hubless fittings are commonly found in Plumbing and drainage systems, particularly in commercial and industrial settings.
