Do fuel injector O rings need replacing?
These rings are made of a type of rubber that is petroleum and hydrocarbon resistant. It is very important to have an effective O-ring that can seal fuel vapors in and keep them from escaping. Note: It is recommended that you replace the fuel injector O-rings with original manufacturer equipment (OEM).

Why do O rings fail?
Cause: Spiralling of an O-ring can occur during dynamic, reciprocating motion, either during installation or in use. The levelling of spiralling is affected by many different factors including, but not restricted to, uneven surface finishes, improper lubrication, friction, installation errors and eccentric components.
Do O-rings wear out?
Nothing lasts forever, but o-rings can break down and fail before their time. If you’re not getting the life from your o-rings that you should, consider the following common reasons for O-ring failure. Keep in mind that most o-rings fail due to a combination of causes.

How do you shrink an O-ring seal?
If you need to change a seal to a smaller size, heating it can cause it to shrink.
- Fill a pot up with hot water.
- Drop the rubber seal into the pot of boiling water for 1 minute.
- Install the rubber seal to check the fit.
- Use a heat gun to shrink rubber seals that need to shrink in place.
Do O-rings expand with heat?
An O-Ring is made of rubber, and rubber reacts to heat. If heated enough rubber expands under heat, and the property’s of rubber is so that i will retain the increased size after heat exposure. So in plane language: Applying heat makes the ring increase in size.
How tight should O rings be?
To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.
What’s the difference between green and black O rings?
Difference between black o rings and green o rings Black o rings are primarily neoprene or Nitrile or, in some cases, a mix of the two materials. Green o rings are hydrogenated Nitrile, also known as highly saturated Nitrile, or more commonly known as HNBR.
