What type of pipe joint permits flexible pipe alignment, is inexpensive to manufacture, and is easy to assemble?

• A. Push on joint
• B. Solder joint
• C. Threaded joint
• D. Welded joint

Answer: (A)

Push-on joints are designed for quick, flexible connections in piping. They let the pipe sit and align with some tolerance, so slight bends or misalignments don’t prevent a seal. The installation is simple: push the pipe into the fitting until it seats, and a built-in seal—often an O-ring or gasket, sometimes with a locking sleeve or clamp—creates the leak-tight connection. Because there’s no heating, threading, or welding required, production costs are low and assembly is fast and straightforward. Solder, threaded, and welded joints all require additional tools, steps, or labor and don’t offer the same easy, forgiving alignment as push-on joints.
