AeroTech RMS-54 54mm ステンレススチール製前方シールディスク - 54FSDSS

Machined perfectly, the forward seal disc slides into the casing with zero resistance and creates a tight seal every time. No fiddling or sanding needed, which saves me a lot of prep time at the launch pad. It's a solid piece of hardware for the price.

Machined the right size the first time, so no sanding or filing to get it to seat flush in the forward closure. The stainless finish also held up fine when I torqued the retainer down, no scratches or burrs.

Finally, a forward seal disc that doesn't feel flimsy—this stainless steel version fits perfectly with my RMS-54 reload kits. The machining is precise and it seals tight without any leaks.
