FEV Fire 1/4 BSP metal 90 degree elbow, with push in connector, with two sizes available, for both 8mm and 10mm tubing. Sometimes a straight version in an extinguisher bottle just doesn't work, but a 90 degree one is perfect and might allow for a more compact installation, with less bending of pipework. Used as a replacement interchangeable item, compatible with many other motorsport extinguisher brands.
