Varian Varian Semiconductor Equipment F9753001 Flange Assembly Apf9 — [SHORT_DESCRIPTION] (Varian)

How Much Does Varian Semiconductor Equipment F9753001 Flange Assembly APF9753001 New Surplus Cost in 2026?

The Varian F9753001 flange assembly typically ranges from $1,008 for used/refurbished units to $2,500+ for new OEM parts in 2026. Refurbished options from vendors like Ferrotec and Axus Technology offer 40-60% savings compared to new units. Condition tiers affect pricing: Grade A (certified refurbished) parts average $1,200, while Grade B (functional but with cosmetic wear) parts like this listing cost $1,008.

Failure to budget for this part can cost $15,000–$25,000 in downtime for semiconductor fabs relying on APF9 systems. Note that Grade B units may show minor corrosion or wear on sealing surfaces, which could require additional inspection before installation. Always verify with the seller if the unit has been pressure-tested recently, as degraded O-rings can lead to costly vacuum leaks.

Varian Semiconductor Equipment F9753001 Flange Assembly APF9753001 New Surplus Specifications and Compatible Tools

This flange assembly is typically constructed from 316L stainless steel, with an outer diameter of 10.5 inches and a thickness of 0.75 inches. It operates at a maximum pressure rating of 15 psig and a temperature range of -40°F to 450°F. Commonly used in APF9 series plasma etch systems, it is compatible with models produced between 2005 and 2012, including the APF9-300 and APF9-450 variants.

Incompatibility warnings apply to later models using the F9753002 flange due to revised sealing groove dimensions. A failed flange can cause catastrophic vacuum loss, leading to $20,000+ in lost production and chamber contamination. Lifecycle metrics suggest these parts typically last 10,000–15,000 RF-hours before requiring replacement. Verify with your tool’s service manual for exact compatibility, as retrofitting may require adapter rings.

What to Check Before Buying a Used Varian Semiconductor Equipment F9753001 Flange Assembly APF9753001 New Surplus in 2026

1. Production Year: Reject units manufactured before 2008, as early batches had a 12% higher failure rate due to inconsistent heat treatment.
2. Sealing Surface Inspection: Use a 10x magnifier to check for pitting deeper than 0.002 inches, which can compromise vacuum integrity.
3. O-Ring Groove Wear: Measure groove depth with a micrometer; deviations beyond ±0.005 inches require replacement.
4. Leak Testing: Request documentation of a helium leak test with results below 1x10⁻⁶ std cm³/sec. Units failing this test should be rejected.
5. Pressure Cycle History: Units with >12,000 pressure cycles may exhibit fatigue cracks at bolt holes, risking $30,000+ in chamber damage.

Purchasing a defective unit can lead to unplanned downtime exceeding $25,000 per hour in high-volume fabs. Always demand a pressure hold test at 10 psig for 24 hours to confirm functionality.

FAQ

Q: Is the used Varian F9753001 significantly cheaper than a new unit?
A: Yes—used/refurbished parts cost $1,008 vs. $2,500+ for new. However, new units come with a 2-year warranty, while used parts typically offer 90 days or less.

Q: Can I use this flange in a Varian APF9-500 system?
A: No. The APF9-500 requires the F9753002 flange, which has a 0.020-inch deeper sealing groove. Using the F9753001 will cause vacuum leaks.

Q: How long does a Varian F9753001 last before replacement?
A: Typically 1
