Why Engineers Specify This Model
- OEM-Matched Geometry — Dimensional tolerances matched to Lam Research chamber specs; no shimming or modification required
- N.C. Fail-Safe Design — Normally closed actuation ensures process chamber remains sealed on loss of pneumatic supply, protecting wafers and process integrity
- Pressure-Rated for Fab Conditions — 0.39–0.59 MPa operating range aligns with standard fab utility air supply specifications
- Traceable Part Numbers — Multiple cross-reference P/Ns (C3419 / 716-140139-211 / E82EV371K2C / 543574) simplify procurement and BOM reconciliation
- Drop-In Replacement — Compatible with existing Lam Research tool configurations without process re-qualification in most PM scenarios

Application-Specific FAQ
Q: Is C3419 compatible with all Lam Research etch platforms?
A: C3419 is documented for specific Lam Research chamber configurations. Please confirm your tool model (e.g., Kiyo, Flex, Versys) when ordering to ensure dimensional compatibility.
Q: What does N.C. mean for this ring component?
A: Normally Closed (N.C.) means the pneumatic actuator defaults to the closed/sealed position when no air pressure is applied — a critical fail-safe feature for process chamber integrity.
Q: Can this part be used in a refurbished tool?
A: Yes. C3419 is commonly specified in refurbished Lam Research tool rebuilds. We can supply new OEM or inspected refurbished units depending on your budget and lead time requirements.
Q: Do you provide a Certificate of Conformance?
A: Yes, CoC documentation is available upon request for all orders. Contact us at the time of purchase.
Q: What is the lead time?
A: Standard lead time is 3–7 business days. Expedited options available — contact support@konmask.com for AOG or urgent requirements.
