FLARING CHOICES FOR PFA, FEP & PTFE TUBING
When PFA & PTFE flare fittings first arrived on the scene in the early 1970s, The only tool for expanding the tube end out to slide over the opposing flare nozzle on the fitting, was a cold plier that simply stretched the tubing outward. It had to be installed very quickly after stretching because the tubing always shrank back to nearly its original size. This method was crude, and put undue stress on the tube and the flare joint. In applications where thermal cycling occurred along with pressure cycling, the joints would eventually leak.
This brought the introduction of our flaring equipment.
Hot flaring has taken over for most installations these days. We offer hot flaring mandrels & kits at extremely good prices.
