Most of the regulations from the Obama administration working their way through the courts raise an issue concerning Chevron deference. The Supreme Court has before it a case, Esquivel-Quintana v. Sessions, raising the question whether Chevron deference trumps the rule of lenity in criminal cases. Auer deference has also come under attack in recent years. As with Chevron, in some circumstances the Court has declined to apply Auer deference altogether. Christopher v. SmithKline Beecham Corp., 132 S.Ct. 2156 (2012). In other cases, individual Justices have argued that it is time to reconsider Auer deference.
Brickeyee is on the point. ALL PEX piping uses some sort of Barb fitting with a compression ring. I have never ever heard of a single failure with this type system. Compression fittings use a ferrule either brass or plastic. The brass ferrule bites into the pipe wall, but the plastic ferrule does not. It is not a surprise to me that a Compression fitting which has a plastic ferrule failed.
Tips & Warnings. 1  Warm your PEX tubing a bit to straighten. 2  Rub with your hands or hold in front of a heat vent. 3  Make sure your ends are round after cutting --- if they are flattened it is more difficult to apply fittings.4  Make sure your fittings are attached securely and properly.nce you have the measurements added, you know how much PEX tubing you need in each size. Some hardware and plumbing supply stores sell PEX by the foot, and some sell in 50- or 100-foot rolls. This is also the time to determine all the fittings you will need to join the Pex tubing.
