Usage/Installation Notes:
-
When replacing fuel injector seals, always replace the old sealing ring if it shows deformation or compression. Using the correct OE washer ensures proper sealing under high injection pressures.
-
Torque tightening of injector/holder must follow manufacturer’s data, and the seal ring must be seated cleanly — debris or old seal remnants may cause leaks.
-
Given that it’s a soft metal washer, it is typically a one-time use item (should be replaced rather than reused).
-
Stocking tip: Typically supplied in a small set (for 4 or more injectors) depending on engine — ensure packaging indicates how many washers are included.
