Description

If you purchased your Bosch Style Aluminum Bypass Valve from JB Performance, it is rebuildable.

2 Flouro-rubber orings are included for sealing the piston to wall.

Please clean all old lubrication out of the valve. Use a ViperLube or TransGel grease to lubricate the new orings before installing the piston. We do not recommend using any other oils or grease to lubricate the o-rings.
