I believe that such a simple problem is still unclear to many experts. In fact, the hydraulic fittings and hydraulic accessories are the same thing. They use some fittings on the hydraulic system, but some people call all the fittings on the hydraulic system as hydraulic fittings. Some people like to call them hydraulic accessories.
But there are still some differences according to the strict distinction of the hydraulic industry. The hydraulic accessories are relatively large accessories on the hydraulic system, such as some hydraulic filters, oil return filters, hy37 mesh filters, ykjd series liquid level control relays, etc. These are hydraulic accessories. The hydraulic accessories refer to small volume, such as pressure gauge, pressure hose and pressure connector, KF type pressure The power meter switch, HF series micro high pressure hose connector assembly, etc. are hydraulic accessories. See here you still don't understand, let me tell you a way, hydraulic accessories are composed of hydraulic accessories.
