KF, ISO and CF vacuum fittings
Vacuum hardware follows three flange families. KF (also called NW or QF) uses a centring ring and an elastomer O-ring held by a hinged clamp — fast, reusable, good to about 10⁻⁸ mbar, sizes DN10 to DN50. ISO-K and ISO-F handle the larger bores, DN63 upward, with claw clamps or bolt rings. CF (ConFlat) uses knife edges biting into a copper gasket, is bakeable to 450 °C and is the standard for ultra-high vacuum.
Read the full guide →FAQ
KF, ISO-K or CF — which flange standard should I use?
KF (quick-release, elastomer seal) for small bores and joints you open often, down to about 10⁻⁸ mbar. ISO-K or ISO-F for larger bores in the same pressure range. CF (knife-edge, copper gasket) when you need UHV below 10⁻⁹ mbar and bakeout — it is more expensive and single-use on the gasket.
Can I mix flange standards in one system?
Yes, with adapter flanges — KF-to-ISO and ISO-to-CF adapters are standard parts. What you should not do is put a CF joint downstream of an elastomer-sealed section and expect UHV: the system's base pressure is set by its worst joint and its worst material.
Do bellows and flexible hoses affect the vacuum?
They add conductance loss and surface area, so a long flexible line costs you pump-down time and base pressure. Formed metal bellows are far better than braided hose for vacuum work; polymer hose should be kept to rough vacuum only.
What material should fittings be for corrosive service?
304 stainless is the general-purpose choice; 316L is the standard where chlorides or acids are involved. Aluminium is used for weight and cost in clean high-vacuum work but not for aggressive chemistry. Tell us the gas and we will specify the material and the seal together.
