Sensus 143-16-021-07 Black Spring

The Sensus 143-16-021-07 Black Spring is a critical component engineered for precise gas pressure regulation within industrial and commercial service environments. Specifically designed for field technicians, this replacement regulator spring is compatible with Sensus 243, 121, and 122 diaphragm-type gas regulators. It provides a specific spring range essential for maintaining outlet pressure control. For Sensus 243-12, 121-12, and 122-12 gas regulators, this black spring delivers a 1-2 PSIG range, while in Sensus 243-8 and 121-8 gas regulators, it facilitates a 2-4.25 PSIG range. This flexibility makes it a standard inventory item for contractors servicing high-pressure gas systems. Constructed from high-tensile materials, it ensures consistent spring rate performance and reliability under heavy-duty cycling, minimizing gas regulator maintenance overhead and ensuring system stability in residential and commercial natural gas lines.

Common Questions

What is the Sensus 143-16-021-07 black spring range?
The outlet pressure range depends on the regulator body. For 12-inch diaphragm models like the 243-12, the range is 1-2 PSIG. For 8-inch diaphragm models like the 243-8, the range is 2-4.25 PSIG.

Is this spring compatible with the Sensus 121-8-HP?
Yes, this black regulator spring is designed to fit the 121-8 and 121-12 variants, providing the specific 2-4.25 PSIG range required for the 8-inch versions.

Can I use this spring for propane applications?
As long as the Sensus gas regulator is rated for LPG and the desired outlet pressure falls within the black spring's 1-4.25 PSIG specifications, it is suitable for use.
