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 high-performance silicone rubber compound. VMQ silicone O-rings are prized for their excellent elasticity, wide temperature range, and resistance to water, oils, and mild chemicals — making them ideal for plumbing, machinery, and hydraulic sealing applications.

Q: What sizes are included in the 30-piece set?

A: These VMQ silicone O-rings feature a cross-section (CS) of 1.8 mm and inner diameters (ID) ranging from 13.2 mm to 20 mm. Please select your required ID size at checkout to ensure a proper fit for your application.

Q: Are these white silicone O-rings suitable for food-grade or water-contact applications?

A: VMQ silicone is generally considered food-grade safe, odorless, and non-toxic, making these O-ring gaskets well-suited for water filtration systems, kitchen appliances, and other water-contact environments. Always verify compatibility with your specific system requirements.

Q: How do I choose the right O-ring size for my machinery or plumbing application?

A: Measure the groove or fitting where the O-ring will sit — specifically the inner diameter (ID) and the groove width, which should match the cross-section (CS) of 1.8 mm. A properly sized O-ring should fit snugly in the groove without excessive stretching or compression for an effective seal.
