Hitachi 883-511 Piston Bumper (4-Pack)

yes good stuff more durability am ok

El producto es de muy mala calidad y no es el que siempre me mandan estoy molesto

I received 4 genuine hitachi piston bumpers, exactly as described. I always use original replacement parts in my Hitachi nailers. This is one part that I would definitely not replace with a cheaper after market one, as the piston driver relies on this piece to be working. A prematurely worn or broken bumper can cause a lot of damage to the driver, which is very expensive to replace. So therefore I use these at a bit of a higher cost and to ensure longevity on the driver. Of course you need to do the other regular maintenance on the guns as well. Good product at a reasonable price.

Expected to get actual Hitachi piston bumpers but instead got this this instead!
