Perfect Circle Fuel Injector O-Ring Kit

The Perfect Circle Fuel Injector O-Ring Kit line provides replacement fuel injector seals (also called fuel injector seal kits or injector O-rings) for engines that use O-ring sealed fuel injectors. Perfect Circle is a well-known name in engine sealing, and these kits are made to restore a reliable seal at the injector.

Key Features:

• Replaces worn, hardened or leaking fuel injector O-rings
• Helps seal the injector at the fuel rail and the intake manifold or cylinder head
• Helps prevent fuel leaks and vacuum leaks that can cause rough idle, hard starting and poor fuel economy
• Designed for a precise fit and dependable sealing in a fuel system environment
• Available in separate upper and lower kits to match the injector sealing location

Replacing the injector O-rings whenever injectors are removed or serviced is a simple, low-cost way to protect the fuel system and keep the engine running as intended.
