International standards allow 37-deg flared hydraulic fittings to be reused, provided they are clean and their threads and sealing surfaces are not damaged. Technicians and mechanics who have successfully completed training for IFPS Certification* in proper procedures for hydraulic line connections know to make sure all threads and mating surfaces are clean and to tighten the fitting nut to the correct torque based on size. However, untrained or under-trained personnel may not understand the importance of ensuring that all mating surfaces of hydraulics fittings are smooth and clean. Furthermore, they may think that the greater the torque applied to a fitting, the less likely it is to leak. Unfortunately, this practice happens all too often with 37-deg. flare fittings, which should be tightened using a torque wrench to within a prescribed window of torque values.

Networx: Pick your plastic plumbing pipe: PEX vs. PVC – Lifestyle – The Columbus Dispatch

Are you planning to install or replace plumbing pipes in your home? You’ve probably heard that plastic pipes made of PEX or PVC are competing with copper in popularity, but what are they, exactly? And PEX vs PVC … which is best for your home? Household plumbing systems use PEX for pipes to supply water and carry away sewage. The term PEX stands for “crosslinked polyethylene.” PEX piping is manufactured by melting high-density polyethylene and extruding it in the form of a tube. This material was first introduced to the United States only 40 years ago, but it’s catching on fast. - Easy install. PEX pipes are flexible and therefore simpler to install than PVC. Your plumber will have to create fewer connections, because PEX can bend to accommodate changes in direction. What’s the payoff for you? Fewer potential sources of plumbing leaks. The small number of connections still necessary will be made using cold expansion rings or crimp fittings. No need for glue, which can leach into the water with PVC pipes. - Compatibility with metal pipes. When a connection to copper or other metal pipes is required, PEX works better than PVC because crosslinked polyethylene won’t corro...
