Pressure Measurement Accessories
Pressure measurement accessories are cocks, siphons, adaptors and protective elements used to connect pressure gauges and instruments safely to the line, protect them and isolate them during maintenance.
They are used to protect instruments from heat on steam lines, to damp surges and vibration at pump outlets and to change instruments without draining the line. Type and size are chosen for the application.
Main Applications
- Gauge connections on steam lines
- Surge damping at pump outlets
- Isolating instruments on chemical lines
- Test and calibration points
- Boiler room measuring points
- Booster and fire pump panels
Technical Data

| Standard | For use with EN 837 gauges |
| Compatibility | Confirmed against the gauge connection size |
Material Options
| Part | Siphon | Snubber | Diaphragm seal |
|---|---|---|---|
| Function | Protects from steam heat | Softens pressure surges | Separates aggressive fluid |
| Material | Steel or stainless (depending on model) | Brass or stainless (depending on model) | Stainless (depending on model) |
| Typical use | Steam and hot water | Pump outlet | Chemical and viscous fluid |
| Connection | Threaded | Threaded | Threaded or flanged |
Which material? On steam lines a gauge must be connected through a siphon, with a cock in between so the instrument can be changed without draining the line. Material and pressure values are confirmed per model.
