Flex-Fit Pipe Attachment
Ideal for quick retrofit to existing processes, the Flex-Fit pipe fitting clamps around a pipe drilled with a small access hole. Flex-Fit has the same sanitary performance as other Keyhole™ Fittings.

This fitting is particularly suitable for use in all-welded pipeline systems.

Keyhole Sanitary RTD - clamp-on pipe fitting
Hybrid Fitting
Ideal for creating combination measurement points to combine the advantages of Keyhole™ temperature measurements with conventional off-the-shelf sensors for Pressure, Conductivity, PH, etc.

Having 2 independent sensors in the same physical location gives best-in-class measurement capability and reduced replacement costs should one sensor fail or be damaged.

Custom Designs
Because our sensors are frequently used to solve measurement problems traditional RTDs and Thermocouples are unable to do, we regularly get asked for custom fittings to fit unique pipe dimensions, end couplings, and multi-port configurations. We have access to world class machining capability to satisfy even the most imaginative requests.
