KF-16 hose adapters connect flexible vacuum hose to a KF-16 (NW16) flange, most often to run a vacuum pump hose to a KF manifold, chamber or instrument. LoCo Science carries two styles: hose barb adapters from 1/4" to 3/4" and PVC smooth hose adapters in 1/2" and 3/4". Both are turned from solid 304 stainless steel bar with no welds.
Which KF-16 hose adapter do I need?
- Connect vacuum hose: Use a hose barb adapter that matches the hose's inside diameter: 1/4", 3/8", 1/2", 5/8" or 3/4". Our silicone vacuum tubing fits our hose barbs.
- Connect PVC hose with a smooth fit: Use a PVC smooth hose adapter, 1/2" or 3/4". A 1/2" smooth adapter fits 1/2" inside-diameter PVC hose.
- Secure the hose: Add a hose clamp over the barb or smooth adapter.
- Connect the flange side: One KF-16 clamp and centering ring set.
Frequently asked questions
What is the difference between a hose barb and a smooth hose adapter?
A hose barb has ridges that grip the inside of the hose. A smooth adapter has a plain outer surface sized for PVC hose.
Which size KF-16 hose adapter do I need?
Match the adapter to your hose's inside diameter.
Do I need a hose clamp?
Yes, we recommend one. A hose clamp over the barb or smooth adapter keeps the hose secure.
