Frequently Asked Questions

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

A: VMQ stands for Vinyl Methyl Silicone, a type of silicone rubber compound known for its excellent temperature resistance, flexibility, and durability across a wide range of conditions. VMQ silicone O-rings are ideal for sealing applications that involve exposure to heat, cold, moisture, ozone, and UV, making them a top choice for both industrial and DIY sealing needs.

Q: What is the cross-section (CS) measurement of these O-rings?

A: These O-rings have a cross-section thickness of 1.8mm. The cross-section refers to the diameter of the circular rubber cord that forms the ring. A 1.8mm CS is a standard size suitable for many grooves and fittings across plumbing, automotive, and industrial applications.

Q: Are these red silicone O-rings waterproof?

A: Yes. These VMQ silicone O-rings are designed to form a secure, waterproof seal when properly seated in a groove or fitting. They effectively prevent fluid and water ingress, making them suitable for use in pumps, valves, connectors, and other wet environments.

Q: Are these O-rings compatible with standard sizing charts?

A: Yes, these are standard-sized O-rings that conform to widely used O-ring dimension standards. Simply match your required inner diameter (ID) and cross-section (CS 1.8mm) to the standard O-ring size chart to confirm compatibility with your application.
