Frequently Asked Questions

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

A: VMQ stands for Vinyl Methyl Silicone, a type of silicone rubber known for excellent heat resistance, flexibility, and chemical compatibility. VMQ O-rings maintain their elasticity and sealing ability across a wide temperature range, making them ideal for demanding machinery and plumbing applications.

Q: Are these O-rings compatible with water and oil applications?

A: Yes. VMQ silicone rubber offers good resistance to water, mild oils, and many common fluids, making these gaskets well-suited for plumbing joints, hydraulic fittings, and general-purpose sealing tasks.

Q: How do I select the correct OD size for my application?

A: Measure the groove or channel diameter where the O-ring will seat. This lot includes multiple outer diameters ranging from 15mm to 30mm, all with a consistent 2.8mm cross-section, giving you a variety of sizes to match your specific fitting requirements.

Q: Can these red silicone O-rings be reused after removal?

A: While VMQ silicone O-rings are highly elastic and durable, it is generally recommended to replace O-rings rather than reusing them after they have been installed and compressed, to ensure the best possible seal integrity going forward.
