iSpring LittleWell Push-Fit Lead-Free Brass Elbow Fitting is the easiest way to make a 90° connection to any combination of Copper, CPVC or PEX Pipe. The elbow fitting features a lead-free solid brass body with push-fit connections to create solid seals. iSpring LittleWell Push-Fit fittings allow you to join copper, CPVC or PEX pipes in any combination with no glue, soldering, clamps or unions. Just insert the pipe and the inside stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is also easy with the use of the simple removal tool so fittings and valves can be easily separated and reused. It can also be used for waste water processing.
