These o-rings fit the hose, Pressure Release button and Trigger Plunger on a Prestaflator tool. Kit also includes internal trigger-plunger washers for 2010 and newer Prestaflator tools.
O-rings made from high quality buna-nitrile (BN70) rubber with a durometer rating of 70. Updated 2013 Plunger seal is more reliable and gives the tool easier trigger regulation and retro-fits to 2010 and newer tools.
Presta Head washers and rebuild kits are now sold separately.
