KF Vacuum Clamp FAQs

1. How do I select the right KF clamp size?

Match to your flange size - KF16 for 16mm, KF25 for 25mm, etc. See our size chart above.

2. What's the proper installation torque?

Hand-tighten plus 1/4 turn with wrench. Typical torque:

KF16: 1.5-2 Nm

KF25: 2-2.5 Nm

KF40: 2.5-3 Nm

KF50: 3-4 Nm

3. When should I choose stainless steel over aluminum?

Stainless steel is preferred for:

High temperature (>150°C)

Corrosive environments

Frequent bakeout cycles

Ultra-high vacuum systems

4. How often should clamps be inspected?

Annually for general use, every 6 months for critical applications.

5. Can I reuse KF clamps?

Yes, but always replace O-rings and inspect for:

Cracks or deformation

Thread damage

Surface corrosion

6. What O-ring materials are compatible?

Common options include:

Viton® (standard)

EPDM (for high temperature)

Silicone (for food/pharma)

Kalrez® (for aggressive chemicals)

7. How to prevent vacuum leaks?

Clean flange surfaces before assembly

Lubricate O-rings lightly

Tighten clamps evenly in star pattern

Perform helium leak check for UHV

8. What's the maximum pressure rating?

Aluminum: 2 bar

Stainless: 4 bar
(At room temperature, decreases with temperature)

9. Can KF clamps be used with corrosive gases?

Yes, with:

316L stainless steel clamps

Chemically resistant O-rings

Proper surface finish (electropolished)

10. Where can I get replacement parts?

Purchase from original manufacturers for guaranteed:

Dimensional accuracy

Material certification

Vacuum performance

Conclusion

KF vacuum clamps provide reliable, standardized connections for vacuum systems across industries. Understanding the size specifications (KF16 to KF50) and material options ensures optimal performance for your specific application.
