Frequently asked questions
How do I choose the right O-ring material?
Match the material to the fluid, temperature, and pressure range. Fluorocarbon often handles aggressive chemicals, while nitrile suits hydrocarbon fluids. Check durometer for compression set and sealing force.
What is the main difference between mechanical seals and gaskets?
Mechanical seals control dynamic fluid leakage at rotating shafts. Gaskets seal static joints between flanges or housings. They use different materials, tolerances, and failure modes.
Why does chemical compatibility matter for gaskets?
Wrong materials swell, harden, or dissolve in the process fluid. This causes leaks or seal failure. Always verify compatibility with the specific chemical and temperature.
What should I check before ordering from a supplier?
Review material certificates, test reports, tolerances, and lead times. Confirm the supplier can provide traceability and meets your required standards.
How do I identify a seal failure?
Look for extrusion, abrasion, thermal damage, or chemical swelling. Failure analysis helps determine if the issue was material, design, or installation related.
What standards apply to industrial seals?
Standards cover sizing, testing, and material properties. Reference relevant standards when specifying parts to ensure consistency and performance.
