Frequently Asked Questions

Q: What does VMQ silicone mean and why is it used for O-rings?

A: VMQ stands for Vinyl Methyl Silicone, a type of silicone rubber known for its excellent flexibility, wide temperature resistance range, and resistance to water, oils, and many chemicals. VMQ silicone O-rings are widely used in machinery, plumbing, and food-grade applications because they maintain their elastic properties over time and under varying conditions.

Q: What is the cross section (CS) and outer diameter (OD) of these O-rings?

A: The cross section (CS) is 5.7mm, which refers to the thickness of the ring itself. The outer diameter (OD) ranges from 30mm to 50mm depending on the size variant you select. Make sure to measure your groove dimensions carefully before ordering to ensure a proper fit.

Q: Are these VMQ silicone O-rings suitable for high-temperature applications?

A: Yes. VMQ silicone rubber is well-regarded for its broad temperature tolerance, generally performing reliably from sub-zero conditions up to elevated heat environments. This makes these O-ring gaskets a great choice for both hot-water plumbing lines and industrial machinery that generates heat during operation.

Q: How many O-rings come in each pack?

A: Each pack contains 5 white silicone O-ring gaskets of the same size, giving you extras for maintenance, replacements, or backup inventory.
