Frequently Asked Questions

Q: What does VMQ silicone mean for O-ring gaskets?

A: VMQ is the designation for vinyl methyl silicone rubber — a high-performance elastomer known for its excellent elasticity, wide temperature tolerance, and resistance to weathering and many chemicals. VMQ silicone O-rings are widely used in plumbing, machinery, and industrial sealing applications where durability and flexibility are critical.

Q: What sizes are included in the 20PCS lot of CS3.5mm O-rings?

A: These silicone O-ring gaskets are available with outer diameters ranging from 24mm to 30mm (OD24–30mm), all with a cross-section of 3.5mm. Each lot contains 20 pieces — select the OD size that matches your application when ordering.

Q: Are these O-rings suitable for both water and oil applications?

A: Yes. VMQ silicone rubber gaskets offer broad compatibility with water, steam, and many oils and fluids, making them suitable for plumbing, hydraulic systems, and general machinery sealing. For highly aggressive chemical environments, always verify compatibility with the specific fluid before installation.

Q: How do I choose the correct O-ring size for my application?

A: Measure the groove or fitting's inner diameter and cross-section width. For these O-rings, the cross-section is 3.5mm and the outer diameter ranges from 24–30mm. Match the OD to your fitting's groove outer dimension to ensure a proper, leak-free seal.
