What type of O rings are fuel resistant o rings? 

The most common use material for fuel resistant is NBR, also known as Buna and Nitrile, and FKM. According to the actual specific working conditions, also can choose HNBR, Fluorosilicone, ACM, ACR, etc.

Why we suggest FKM O rings?

Speaking of this question, we have to talk about the advantages that FKM O ring has when it is compared to other types of rubber o ring at fuel relative industries.

Let's compared the most two common rubber choices for fuel resistant O rings. You also can check the performance difference below, there is a chart shows. If you didn't find the data you want, feel free to CONTACT US to ask for relative data sheets.

1. FKM can resistant to around 200℃, at static state with hot air, which is much higher than NBR does. But NBR does better at lower temperature

2. FKM has lower compression set than NBR

3. FKM has longer service life than NBR in fuel

The only disadvantage of FKM is the price, it is much higher than NBR. But when you compared to HNBR, Fluorosilicone, FKM O ring is cheaper and more cost-effective.

So, if you have enough budget, and you attach great importance to service life, we would prefer to suggest you FKM as the material of fuel resistant O rings.
