1/4 in NPT 0–300 PSI Center-Back-Mount Pressure Dial Gauge

The center-back-mount arrangement is the defining feature of this 0–300 PSI dial pressure gauge. Its product record also lists a 1/4 in NPT connection and 2 in face. Together, these details identify a threaded equipment or line-pressure instrument with a rear connection, rather than a handheld tire-valve pressure checker.

A rear connection changes the physical route between the pressure point and the dial. Compare this layout with the original gauge and the available space behind the face. The center-back description establishes connection position; it does not establish a panel-mount flange, fixing bracket or included installation hardware. Where an enclosure or mounting surface surrounds the instrument, use the case outline and connection drawing to assess the complete installation.

Keep this version distinct from the 0–300 PSI bottom-mount gauge in an equipment-parts catalogue. Both share the published 2 in face and nominal 1/4 in NPT connection, yet the pressure connection approaches the dial from a different direction. That distinction matters to replacement fit even before comparing any additional instrument requirements. The published scale also should remain part of the order description, particularly where several ranges are stored under similar names.

For a quotation, specify center-back mounting together with range, nominal thread and quantity. Add the original part reference or a drawing when rear clearance, overall depth or the position of the dial must match existing equipment. The listing does not assign a process medium, accuracy class, filling type or temperature rating, so these cannot be assumed from the mounting arrangement. An approved configuration reference helps a distributor keep repeat supply consistent.

Product FAQs
1. Where is the pressure connection on this gauge?
The product title identifies center-back mounting: the connection is positioned behind the dial. Use the installation drawing to check the complete rear connection and case envelope.

2. Does center-back mounting mean panel hardware is included?
No panel flange, bracket or fixing kit is identified in the available record. Center-back describes connection position; any separate mounting hardware must be specified independently.

3. What is the corresponding bottom-mount configuration?
The 1/4 in NPT 0–300 PSI bottom-mount gauge lists the same scale and face diameter with a different connection position. Compare the equipment layout before selecting either configuration.

4. Which details should stay on a repeat purchase order?
Retain the 0–300 PSI scale, nominal 1/4 in NPT connection, 2 in face and center-back-mount description. Attach the approved drawing or sample reference where case depth or rear clearance controls fit.
