Vacuum fittings: KF40-40>25; KF25>19; KF40 for 19mm hose; VTR-19 tubing; SS Vac bellow KF40; plus KF clamps + rings
VACUUM CONNECTION FITTINGS

All NW/KF style vacuum connections conform to the international ISO 2861/I standard. KF series quick release flanges also comply with Standard GB4982-85.
Other vacuum components, which may include three-way types, blind plates, metal flexible corrugated pipes, callipers and bolts, heel blocks and holders, comply with the ISO Standard 9000:2000.
They are widely used in the assorted vacuum systems and low-voltage pipe systems, such as electronic, food machinery, the petrochemical industry, and medicine machinery.
Our vacuum fittings come with plastic protective caps which help protect the NW/KF flanges from scratches and dust.

Copper Gaskets for CF Flanges

COPPER GASKET FOR CONFLAT VACUUM SYSTEM

Copper, the normal gaskets for stainless steel CF flanges are punched from 1/4-hard, high purity, oxygen-free (OFHC) copper stock, chemically cleaned and finished to be scratch and burr-free. Can be heated up to 450°C in flange assembly. Metal wire gaskets made of copper, gold or indium can be also be used.

Metal gaskets are impermeable to gases and withstand moderately high temperatures indefinitely. The CF flange is the most widely used For high vacuum and UHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.
ProSciTech stocks a range of indium wire.

CF systems use a copper gasket and knife-edge flanges to achieve the high vacuum seal and can operate down to 10-13 torr (10-11 Pa) and can be heated to 450°C for bake-out.
