The Plastic Pipe Institute even supports the use of PEX fittings under concrete and in-slab application, although it’s still a good idea to use as few fittings as possible to reduce the risk of leaks. These pipes require few directional fittings due to its high. The PEX pipe is attached onto the barb of the fitting and under the sleeve.
