In this today's episode of the Build Show, builder expert Jordan Smith teams up with Matt Risinger to revisit a classic experiment: pushing PEX fittings to their absolute limits. Using a high-pressure testing rig, they put five different connection types—SharkBite push-to-connect, SharkBite clamp, SharkBite crimp, Viega crimp, and Uponor ProPEX expansion—to the ultimate blow-off test. From surprising early failures to dramatic mid-pipe ruptures, the results reveal not only the durability of various fittings but also some unexpected truths about PEX piping under extreme stress. With safety goggles on and cameras rolling, Jordan and Matt deliver hands-on insights, plenty of building science expertise, and a few laughs along the way.
