Swagelok® Tube Fittings—Special-Purpose     
The gaugeable Swagelok tube fitting design is available in special configurations:

• Dielectric fittings
• Chromatograph fittings
• Flange adapter fittings

Dielectric Fittings
Dielectric fittings isolate monitoring instruments from the effects of electrical current. The fittings interrupt cathodic current flow while permitting full fluid flow.
