Plastic Upper O-Ring Retainer for Denso or Bosch Fuel Injectors

Plastic Upper O-Ring Retainer for Denso or Bosch Fuel Injectors

Replacement plastic upper O-ring retainer used on select Denso and Bosch fuel injector applications.

These retainers can become cracked, broken, or lost during injector removal or servicing.

Make Installation Easier

Installing these retainers by hand can be difficult because the retainer must expand over the injector body before seating into position. Our Bosch / Denso Upper O-Ring Retainer Installation Tool provides a simple, controlled way to expand and press the retainer into place while reducing the chance of damaging the new retainer.

Plastic color may vary.

Contact us before purchase if you are unsure of fitment.
