6. Frequently Asked Questions (10 Expert Answers)

Q1: What vacuum range do these elbows support?
A: Designed for high vacuum applications from 10⁻³ to 10⁻⁶ mbar.

Q2: How do I select the right size?
A: Match to your existing tubing - common sizes are KF16 (DN16), KF25 (DN25), etc.

Q3: What maintenance is required?
A: Inspect O-rings annually and replace if worn. Clean flange surfaces before reassembly.

Q4: Can these withstand aggressive chemicals?
A: 304 stainless steel offers good chemical resistance, but for harsh environments consider 316L.

Q5: What's the temperature limit?
A: Standard Viton O-rings are rated for -20°C to 200°C. Higher temperatures require special O-rings.

Q6: How do I check for leaks?
A: Use a helium leak detector or monitor vacuum gauge response during pump-down.

Q7: Are these compatible with other flange types?
A: Yes, with proper adapters they can connect to CF, NW, or other flange systems.

Q8: What torque should flange clamps use?
A: Typically 2-3 Nm for KF16-KF25, 4-5 Nm for KF40-KF50 sizes.

Q9: Can I get custom angles?
A: Standard is 90°, but 45° and other angles can be custom manufactured.

Q10: How long do O-rings last?
A: With proper care, 3-5 years in normal service conditions.
