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.

NW/KF Flange Adapters to Male NPT Thread

male NPT adapterUsed to connect pipes and systems with NPT thread to NW/KF flange system. Stainless steel adapters are welded and helium leak tested. Aluminium adapters are made from one piece (more cost effective alternative). Use Apiezon AP101 anti-seize vacuum grease as a sealant and to prevent seizing. Please note that NPT (National Pipe Thread) does not refer to the outside diameter of the thread.

KW/KF Flange Adapters with Female 1/8

Adapters to NPT Thread Female and Male NPT Flanges and Adaptive Tees

NW/KF NPT vacuum connectionUsed to connect pipes, systems and thermocouples (1/8") with NPT thread to NW/KF flange system. Commonly used to connect filters with NPT thread on adapters on the exhaust port of rotary vane pumps. Use Apiezon AP101 anti-seize vacuum grease as a sealant and to prevent seizing. Please note that NPT (National Pipe Thread) does not refer to the outside diameter of the thread.


These NW/KF Flanges with 1/8" thread can be used with the P-100 Pirani Gauge to connect the P-100 Gauge to pumps and systems with standard NW/KF/QF flanges.
