10 FAQs About KF 4-Way Crosses

1. What is the difference between ISO-KF, QF, and NW flanges?

These terms are interchangeable—ISO-KF (QF/NW) refers to the same flange standard.

2. Can KF 4-Way Crosses handle ultra-high vacuum (UHV) conditions?

Yes, when paired with proper sealing (Viton or EPDM O-rings).

3. Are custom sizes available?

Yes, we provide OEM customization for unique flange dimensions.

4. What clamp types are compatible?

Standard wing-nut clamps (KF clamps) are used for secure fastening.

5. How do I prevent leaks in vacuum systems?

Ensure proper O-ring seating and use high-quality stainless steel fittings.

6. What certifications do your KF crosses have?

ISO 9001, CE, and RoHS compliance for industrial safety.

7. Can I use KF 4-Way Crosses with aggressive chemicals?

Grade 316 stainless steel offers better chemical resistance.

8. What’s the lead time for bulk orders?

Typically 2-4 weeks, depending on order volume.

9. Do you provide installation support?

Yes, we offer technical guides and engineer consultations.

10. How do I clean and maintain KF vacuum fittings?

Use alcohol wipes or ultrasonic cleaning for optimal performance.
