Tube Fittings

Tube fittings for use in vacuum lines or sterile applications, where cleanliness and He-leak tightness are critical. Tube fittings have ferrules which crimp the outside diameter of the tube. Compression-type fittings have excellent tolerance to vibration, thermal cycling and can be reassembled with consistent dimensions of plumbing lines.
