Brass Reusable Socketless Fitting, 0.38 Compression Tube, -06 Hose, Straight

Reusable is exactly right. The 4750 Series uses a compression-type design, so there's no crimping or swaging involved. You thread the fitting components together by hand or with standard wrenches, which means you can disassemble it, swap it onto a new hose section, and reassemble without shop press equipment. That's the whole point of the socketless design for field repairs and situations where you don't have a crimp station nearby.
