Seamless or welded 304L stainless tubing

yeah i went thru a few bldes in the ole rigid tubing cutters that stainless is some tough ish

Travis from Metal-Werx is correct if you used seamed stainless tubing with AN fittings more than likely it will leak. Swagelock is pricey but is the way to go. Just make sure the tube is seated into the fitting all the way before tightening otherwise you cuss and have to buy another fitting because the ferrel will not budge on the tube after tightening. (been there - done that)

Yeah its a hand tool. Its just like the little benders for brakeline, but it is bigger. Id say the handles are about a foot and a half long. Has about a 3" radius.
