What is a good lubricant for O rings? As most O-rings and seals are made of synthetic elastomeric polymers, i.e., “rubber” material such as nitrile, EPDM, and Neoprene, they are the best lubricants for them derived from synthetic compounds. At the top of the list is silicone-based and ester-based lubricants.
Can you use Vaseline to lubricate O rings? With this in mind, you should have no worries about whether to utilize Vaseline on any of the o-rings. Vaseline is a very mild petroleum product. If it wasn’t, we wouldn’t use it in so many products which involve skin care. If o-rings were actually made of rubber, then there would be concern.
What oil is best for O rings? Pure silicone oil used as an O-ring lubricant allows for better installation and protects the gaskets from damage.
Can I use wd40 on rubber O rings? What surfaces or materials are OK to use WD-40 on? WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint.

Is dielectric grease OK for O rings?
Dielectric grease is a non-conductive silicone grease developed to seal moisture and thus prevent corrosion on electrical contacts. It is important to note that the dielectric grease will melt the silicone rubber over time and therefore should not be used for connections such as o-rings made with this rubber.

If you want the installation process to go smoothly, you should use silicone lubricant during the installation. Make sure that lubricant is important during installation as it not only ease the process but it ensures that the O-ring sits perfectly.
Should you lubricate O rings?
Lubricating an O-ring is an important part of the assembly line process as it can help protect an application from abrasion or scuffing damage. The addition of a lubricant can extend the operating life of the O-ring by creating a barrier film over its surface.
How do you keep O rings from drying out?
O-rings must be stored below 100° F (38° C). Like food items, colder temperatures mean better preservation. But before installation, O-rings must be brought back to room temperature to remain flexible. Humidity must be monitored carefully as well, as dry environments will affect the rubber.
