This is an aftermarket part, not an original manufacturer part. Instrument names and part numbers identify what it fits and replaces; they remain the trademarks of their owners. The manufacturer, country of origin, rated life and warranty are stated in the quote, before you decide anything. If you need the OEM part, say so and I will quote that instead.

Needle seal, Vespel, for Shimadzu LC-2010 and SIL-10ADvp

Replaces OEM part number: 228-33355-04

Vespel needle seal for the LC-2010 and SIL-10ADvp, cross-referenced to 228-33355-04. Vespel is the harder of the two materials Shimadzu uses here and it lasts longer, but it is less forgiving of a needle that is not perfectly aligned, and it dislikes high pH mobile phases. If your method runs above about pH 9 the PEEK version is usually the better choice. A worn seal leaks at injection, and the symptom is low and slightly variable areas rather than an obvious failure.

Before you order: if the instrument is misbehaving, tell me the symptom, not the part number. Lamps and seals get replaced for problems they did not cause. The first look costs nothing, and if this part is not the fix, I will say so.
