These genuine OEM Honda seals stop any leaking that might be occurring form around the fuel tank filler cap.  After time all seals will become dry, brittle, and cracked.  This is especially true in the area of fuel seals.  Replace your seals with only genuine Honda seals to ensure a long lasting exact fit. 

This seal fits all Honda CB175's, CL175's, and SL175's.  Need a gas cap?  Yah, we have those too.
