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 TO SWAGE-LOK® ADAPTERS
The NW/KF to Swagelok® Adapters allow the connection of small tubes with the widely used Swagelok® connectors. Enables easy connection to existing small diameter tube constructions for evacuating the tubes. Ideal for research, instrumentation and experimental set-ups. All stainless steel 304 construction. Available for 1/8", 1/4", 3/8" and 1/2" tubes.
NW/KF Flange Adapters to Male NPT Thread
Used 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.
Adapters to NPT Thread Female and Male NPT Flanges and Adaptive Tees
Used 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.
NW/KF Adaptive Tee to Female NPT
In-line Tee connectors with 1/8" and 1/4" female NPT thread. Made out of a solid piece of 304 stainless steel. 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.
NW/KF QUICK COMPRESSION COUPLER
These NW / KF to Quick Compression Couplings allow the connection of standard tube or vacuum gauges to vacuum systems. Available for several standard tube sizes on NW16, NW25 and NW40. A convenient way to connect tubes without the need for welding. Ideal for temporary, test and research set-ups. Allows for adjustment and can be easily removed for a vacuum system. All stainless steel 304 construction with adapter, compression ring, cap and O-ring.
BLANK PLUGS FOR QUICK COMPRESSION COUPLINGS
Use the blank plug to close an unused compression coupling. Made from 304 stainless steel.
