Choose the SDR family first
A similar body does not guarantee the same function. Confirm the function and interface first, then compare size and installed dimensions.

About SDR
SDR100 and SDR200 are compact regulators. Standard models publish a 0.05–0.9 MPa adjustment range; L low-pressure models publish 0.03–0.4 MPa. A gauge, bracket, gauge scale and thread are code-level choices, not separate product pages.

Matching Questions
Is an SDR low-pressure L model interchangeable with a standard SDR?
No. The published adjustment ranges differ. Confirm the full code, required outlet pressure, port and gauge arrangement before RFQ.
