- Compatibility and Flexibility
- Smaller Environmental Footprint
How It Works
A Unique Protective Barrier for Aseptic Applications
The aSURE™ Instrument Tee incorporates an elastomeric diaphragm directly into a sanitary instrument fitting — no solvents, no adhesives. The result is a gendered connection point that accepts virtually any standard 1.5" sanitary pressure sensor. Manufactured to ASME-BPE specifications and constructed with materials extensively tested for biocompatibility and extractables, aSURE™ Instrument Tees are built for demanding bioprocess applications.
Sterile Barrier by Design
The elastomeric diaphragm creates a continuous sterile barrier between the process fluid and the pressure sensor — eliminating dead legs and reducing contamination risk.
Superior Measurement Accuracy
Direct diaphragm contact with the process fluid delivers reliable, repeatable pressure readings without signal attenuation or offset from fluid column effects.
Universal Sensor Compatibility
Accepts virtually any standard 1.5" sanitary pressure sensor — integrates into existing process lines without instrument changes or adapters.
Reduced Environmental Footprint
Single-use format eliminates cleaning validation cycles and reduces water, chemical, and energy consumption compared to reusable alternatives.

Choose Your Instrument
Traditional fixed or tethered pressure sensors offer unique advantages over single-use pressure sensors in terms of accuracy, simplicity, and reliability. The aSURE™ instrument fitting eliminates the need for single-use pressure sensors and offers the flexibility to choose virtually any 1.5″ sanitary pressure-sensing instrument.
Additionally, the aSURE™ instrument fitting provides a practical solution for maintaining an aseptic barrier on complex manifold sets, eliminating the need for a gauge during the sterilization process.
The aSURE™ Tee is compatible with all common styles of sensors.
