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

For buyers specifying a 0–300 PSI pressure scale, this AUTOWIN configuration combines a 1/4 in NPT connection with a bottom-mount layout and 2 in face. It belongs in an equipment-parts or line-pressure instrument comparison. Its threaded mounting format does not describe a handheld tire gauge, tire-valve chuck or inflation-hose assembly.

Connection position is a practical distinction within the 0–300 PSI range. This version has the connection below the dial, while the separately listed center-back-mount version routes the connection behind the face. Both listings state a 2 in face and nominal 1/4 in NPT thread, but they should remain separate stock items because their installation layouts differ. A replacement should match the intended connection approach and viewing position.

The pressure range is another ordering distinction. Retain 0–300 PSI in the model description when requesting quotations or comparing samples with lower-range bottom-mount instruments. A wider scale is not evidence of a stated accuracy class, improved readability at every pressure or compatibility with a specific process medium. Those properties are not established by this product record and should not be inferred from its high-pressure description.

For an equipment maintenance order, provide the original instrument reference or installation drawing alongside the required quantity. For distributor stock, use separate order lines for different ranges and mounting positions, even where the product photographs appear similar. Record the 2 in face as the published face dimension and obtain the case outline where depth or surrounding clearance determines fit. An agreed sample or drawing then gives repeat orders a concrete configuration reference.

Product FAQs
1. Which details identify this bottom-mount version?
The listing identifies a 0–300 PSI scale, a nominal 1/4 in NPT connection, a 2 in face and bottom mounting. Keep all four details in the purchase description.

2. Is it interchangeable with the center-back-mount version?
The 0–300 PSI center-back-mount gauge has a different connection position. Match the installation layout and viewing position before treating either version as a replacement.

3. Does the high-pressure description establish a specific accuracy class?
No accuracy class is stated in the available product record. The 0–300 PSI entry identifies the published pressure range and should not be used as an accuracy or calibration claim.

4. What if the replacement specification calls for 0–160 PSI?
Compare the separate 0–160 PSI bottom-mount gauge against that requirement. Keep range selection explicit rather than substituting another scale solely because the nominal NPT connection matches.
