Perfect Circle Fuel Injector Kit

The Perfect Circle Fuel Injector Kit line provides replacement fuel injector seals and O-rings. Each kit is for sealing fuel injectors in the engine. Depending on the application, you may see these parts called a fuel injector seal kit, fuel injector O-ring kit, or injector seal set.

Key Features:

• Replaces worn, hardened or leaking injector seals and O-rings
• Helps keep the fuel injector sealed against fuel leaks and air or vacuum leaks
• Made by Perfect Circle, a brand known for engine gaskets and sealing products
• Engineered for application-specific fit, with each kit listed under its own part number

Replacing injector seals whenever injectors are removed helps restore a proper seal and supports reliable fuel delivery and engine performance. Choose the kit that matches your engine application.
