低音量插入管，1.500" (INS-U-3)

After swapping in this tube, my torch is back to that precise, low flame I need for fine soldering work—the 1.500" length sits exactly where it should. Only the tube arrived, so make sure you've got your collar and screw handy, but for the price, it's a solid replacement part.

The fit is exactly right for the replacement part I needed—it slid right in without any modification. Just wish the set screw was included, but it's working perfectly with my existing hardware.

The precision-machined tube fit snugly into my furnace without any filing or adjustment needed. It's noticeably tighter than the worn part I replaced, which should help regulate the low-burn rate better this season.
