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.

45° ELBOW
These Elbow 45 Degrees fittings follow ISO-KF standards. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centring ring form the vacuum seal between the connecting flanges. The centring ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive resistant stainless steel.

STRAIGHT STAINLESS STEEL CONNECTOR
Also know as a full nipple straight connector.
Made from SS304.
We fabricate these KF (QF) nipples (spools) for HV systems from tubing and KF flanges. The KF (QF) flange is used for through- or foreline vacuum plumbing and for simple HV chamber ports.
Special specifications can be custom made - ask.
Wire reinforced thick wall PVC pipe
Thick‐walled PVC with a steel wire spiral inside the tubing wall. The wire spiral is Stainless Steel and is embedded in PVC plastic ‐ smooth tubing inside and outside.
Use with hose adapters and hose clamps to make custom vacuum system or pressure hoses.
This tube/hose is suitable for both pressure and vacuum.
Constructed of corrosion‐resistant PVC, can be used to transport various chemicals in areas with tight turns and sharp bends. Its bend radius is approximately four times the I.D. PVC is suitable for application at temperatures from ‐12°C to 65°C.
This tubing available in the following inner diameter millimetres: 6, 9, 12, 19, 25, 38, 50.
2 week lead time on products not in stock.
Tubing is supplied in continuous length to order.

KF fittings (Standard unbraided wall)
A superior alternative to rubber or reinforced plastic hoses. These durable, thin walled, flexible stainless steel hoses do not alter or crack like rubber or plastic hoses and do not collapse under vacuum, have less connection parts and therefore introduce less possible leaks in a vacuum system. NW/KF flexible metal hoses are made from 304 stainless steel and may be cleaned with solvents. Dry and clean SS is most suitable for high vacuua.
These stainless steel hoses/bellows are designed to curve but not to expand or contract in length. The 25mm bellow may be rolled up to a minimum 300mm diameter roll. Excessive flexing may lead to metal fatigue. These bellows are excellent for connecting low and high vacuum pumps to each other or to working chambers.
The space within the bellows (or vacuum hose) adds to the pumped space, but larger diameter bellows/ tubes transmit vacuua better. Keep vacuum connections as short as practicable.
