Vacuum components are important parts of vacuum technology. These are all components of vacuum equipment which are necessary for the assembly of vacuum lines, e. g. flanges, seals and tube components (elbows, tees, crosses etc.). Applications in vacuum technology make high demands on the selection of material as well as the fabrication of these components.Â
1.Product Feature These KFto KF conical reducer vacuum 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 centering ring form the vacuum seal between the connecting flanges (please see top right figure - click to enlarge). The centering 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.
High vacuum rated to 1x10-8 Torr Temperature rated to 200ºC maximum Symmetric, nonrotatable geometries Rotatable Bolt Rings available for LF sizes Viton O-rings Standard matte finish NW16 through NW50 sizes Body type dependent on tube size Â

FAQ Q1. Are you a trading company or factory?   Without doubt, We are a manufacturing factory.
Q2. Do you have FDA certificate for the materials? Yes,because FDA is a basic and very important certificate for the food processing machines.
Q3. How do you control the quality? Quality control is very important to avoid material mixing and poor quality. We control the quality from beginning to the end. We only have 304 and 316L two different materials. 100% inspection on raw materials. And during the production, different materials in different places. After materials are finished, we choose 10%  for inspection. If there is 0.1% problem in 10%, then no excuse to go ahead for inspecting 100% of the materials.
Q4. About chemical components This is first concerning for customers. We take our materials to our laboratory for each lot. You may ask for the  laboratory report any time.Â
Q5. If there is any quality problem, how do you solve it? We are very proud that we never let one customer leave us. We are not 100% perfect,and there are some  quality problems. But We try our best to provide the correct materials in the beginning , so that we take  less  time for quality problems. If there is any quality problem, we take the responsibility. We believe what we are doing together,  it will get backtomorrow. If we always take our responsibility, we keep our customers with us. If not, customers will leave us.  Q6. How long is your delivery time?   For normal products in 10-15 days; for bulk order, in 25-30 days. It depends.
Q7. Warranty  3 years warranty for all of our stainless steel products. Gaskets are not included due to the different application for customers.Â
