DEBURRING PRIOR TO FLARING

CONNECTORS

To en su re sati sf act or y a re pro duc ti o n, tu be end de bu r ri ng mi gh t be requ ir ed prior to aring. It is usually necessary to break the inside corner smoothly before single aring. In addition,

some non-ferrous tubing is normally

required to eliminate the cutoff burr, wh ich mig ht oth erw i se cre ate lea ka g e pa ths acr oss a sub s ta nti al po rti on of the are. Smoothly breaking the outside corner prior to single aring, or both the outside and inside corners prior to dou bl e a r in g, is ac cep ta b le for any tube material to minimize splitting.
