Application
Range springs are used during regulator servicing, repair, or pressure range conversion. Replacing a worn or fatigued spring with a genuine Sensus part ensures the regulator maintains accurate outlet pressure and meets safety and performance standards. Color-coding (red) allows technicians to quickly identify the installed pressure range without referencing documentation in the field.
Why Choose Genuine Sensus Parts?
Using OEM-specified components like the 143-16-021-03 red spring ensures proper fit, function, and longevity within your Sensus regulator assembly. Non-OEM springs may not meet the precise load characteristics required for accurate pressure regulation, potentially leading to pressure drift or unsafe operating conditions.
