For a Walvoil hydraulic setup that uses an FS-SD8/RC-SAE outlet cover, this part is the end cover that closes out the outlet side and gives you a secure connection point in the system.

Outlet covers like this one seal off unused outlet ports on hydraulic valve sections. On the SD8 series from Walvoil, that's a real working function, not just a dust cap. It keeps the circuit closed and pressure contained at any port you're not actively running a line out of. Without it seated properly, you'd be looking at leaks or pressure loss at that section.

That is correct. This outlet cover is designed to integrate seamlessly into your hydraulic systems, providing a secure and efficient solution.
