Replacement & Compatibility FAQ
Q: Is the TESCOM C3050 a direct drop-in replacement for the 12-1K21AAED-072?
A: The C3050 shares the same SR-40 platform and 1/4″ VCR port pattern. Verify the spring range suffix and seat material before substituting in a certified system.
Q: Can I use the HT-110 as a replacement?
A: Yes, for applications above 120°C. The HT-110 uses a high-temperature diaphragm and seat; confirm compatibility with your process gas and temperature profile.
Q: What is the lead time for the 12-1K21AAED-072?
A: In-stock units ship within 1–3 business days. Contact us to confirm current stock levels.
Q: Do you provide material traceability certificates (MTR)?
A: Yes, MTRs and 3.1 material certs are available upon request for semiconductor and pharmaceutical applications.
Q: Can Konmask cross-reference my existing part number to a compatible equivalent?
A: Absolutely. Send your part number, application details, and pressure/flow requirements to support@konmask.com for a free selection review.
