This translucent washer is designed for Crown/Samucksa Knee Lever - Neo Edition.
Compatible with Sanwa JLF Shaft Cover
This washer will work with the shaft cover of Sanwa JLF-CD Shaft & Dustwasher Set Black, but the shaft cover for this model is not compatible with the standard Sanwa JLF shaft. You should instead try Sanwa JLF-CD Clear Shaft & Matching Dustwasher Set
