1.VMQ(Silicone)O-Ring Performance Specifications
VMQ(Silicone)o-rings are high-performance elastomers known for their wide temperature range and excellent flexibility.Silicones possess excellent resistance to extreme temperatures-50℃ to+232℃(-58°F to +450°F).Some special compounds resist even higher temperatures.Silicone O-rings with a hardness of 70 Shore A offer excellent resistance to ozone,UV,aging,and weathering.They operate in a wide temperature range from-60℃ to+200℃,and can even withstand short-term temperatures up to +230℃ . VMQ silicones are particularly resistant to extreme temperatures,ranging from-60C to +200C.These vmq o ring components are highly resistant to UV radiation,ozone,and weathering.Certain low outgassing silicone compounds prevent the release of vapors in sensitive optical environments.Sil-Glyde silicone lubricant is recommended for installation, as it protects rubber parts,prevents drying out and cracking,and ensures smooth assembly without tearing.
2.Laser Cutting,Plasma Cutting,and Engraving Machine Conditions
Precision thermal processing equipment such as fiber laser cutting machines,plasma cutters,and laser engraving systems requires contaminant-free sealing to protect optical paths and lenses.Silicone O-rings and washers are commonly used in CO2 laser focus lenses and cutting head assemblies,including Precitec and Raytools heads.The O-Ring Silicone Washer provides a durable,reliable seal for laser focus lenses,withstanding wear and radiant heat.In laser cutting and engraving machines,seals in gas assist nozzles and protective lens housings prevent dust ingress that could distort the beam or cloud expensive optics.Low outgassing VMQ compounds are selected to avoid releasing chemical vapors that might contaminate lenses during high-heat metal or wood cutting processes.The AS-010 size is frequently used in small-diameter gas line fittings,lens retaining rings,and optical housings where thermal stability is essential.

Conclusion
For maintaining the integrity of fiber laser cutting machines,plasma cutters,and engraving equipment,VMQ o-rings provide reliable thermal and optical stability.Using Sil-Glyde lubricant during installation of the AS-010 seal helps prevent damage and ensures a leak- free environment for assist gases and lens protection.Always select low outgassing silicone compounds and verify seals are clean and particulate-free before installation in cutting or engraving systems.
