Frequently Asked Questions – Stamping Jacket Gasket
What is the difference between stamping and double jacket gaskets?
Stamping jacket gaskets are produced by high‑speed punch presses, making them ideal for large volumes and cost efficiency. Double jacket gaskets are typically fabricated by welding or folding, offering more design flexibility for complex shapes.
What filler materials are available?
We offer expanded graphite, PTFE, ceramic fibre, and mica. Selection depends on temperature, pressure, and chemical compatibility.
Can you add partition bars to the gasket?
Yes. Partition bars can be integrally formed or welded into the gasket, allowing separate flow paths in heat exchangers or multi‑pass systems.
What jacket thickness do you offer?
Typical jacket thickness ranges from 0.2 mm to 1.0 mm, depending on size and material. Custom thicknesses are available upon request.
Do you offer full‑face and partial‑envelope options?
Yes. Full‑face jacket provides maximum protection, while partial‑envelope allows higher resilience. Choose based on bolting and pressure requirements.
What is the typical lead time for stamping jacket gaskets?
Bulk orders: 15–25 days; samples: 5–7 days. Express shipping available.
