DK-LOK® Calibration Fittings connect directly to the bleed port of a differential pressure transmitter, helping to simplify the calibration process. Two sizes of threads are available to fit the vent port of Yokogawa/Rosemount, and Honeywell differential pressure transmitters. The conical metal-to-metal sealing face on the straight thread requires no PTFE tape. View Tube Fitting Catalog

Dielectric Unions

The DK-LOK® Dielectric tube fitting is designed to apply where static electrical currents flowing through a pipe or tubing line must be interrupted to protect instruments. The DK-LOK® Dielectric tube fitting is commonly used in natural gas transmission stations where they are installed on impulse lines. This fitting interrupts cathodic current flow while permitting full fluid flow. View Tube… Read more »
