The Mityvac MVA6178 Replacement Vacuum Gauge is a genuine replacement vacuum measuring gauge designed for compatible Mityvac and Selectline hand-operated vacuum pumps, including the Mityvac MV8010 Selectline pump supplied in the MV8000 Automotive Tune-Up and Brake Bleeding Kit.
Featuring a 2-inch (approximately 50mm) diameter dial, the MVA6178 provides a clear vacuum measurement scale covering 0 to 30 inches of mercury (inHg), equivalent to approximately 0 to 100 kPa of vacuum.
This professional replacement gauge incorporates a diaphragm-operated measuring mechanism and a specially designed mounting stem that allows the gauge to be rotated through 360° for improved visibility during use.
The stem design also enables convenient pin-release removal, allowing the gauge to be removed from a compatible pump when servicing or replacement is required.
The Mityvac MVA6178 is suitable for replacing an original worn, damaged or faulty gauge on compatible Mityvac hand pumps. It can also be used as a gauge addition for compatible Mityvac pumps originally supplied without one.
Designed for automotive vacuum diagnostics, workshop maintenance and hand vacuum pump servicing, the MVA6178 helps keep existing Mityvac equipment operational without needing to replace the complete hand pump.
Important: This listing is for the replacement vacuum gauge only. The Mityvac MV8010 hand pump and complete MV8000 kit are not included.

Replacement gauge only – hand pump not included
Compatible with the Mityvac MV8010 Selectline Hand Pump
The Mityvac MVA6178 is designed for the MV8010 Selectline hand-operated vacuum pump.
The MV8010 is the vacuum pump supplied within the popular Mityvac MV8000 Automotive Tune-Up and Brake Bleeding Kit.
The MVA6178 provides a replacement option when the original gauge becomes damaged, unreadable or no longer operates correctly.
Replacing the gauge can allow an otherwise serviceable MV8010 hand pump to remain in use.
For clarity, the relevant model references are:
MVA6178 – Replacement vacuum gauge
MV8010 – Compatible Selectline hand vacuum pump
MV8000 – Automotive Tune-Up and Brake Bleeding Kit containing the MV8010 pump
The MVA6178 replaces the gauge component, not the complete pump assembly.
2-Inch / 50mm Vacuum Gauge
The MVA6178 features a 2-inch dial, equivalent to approximately 50mm in diameter.
The dial provides a clear indication of vacuum levels during manual pump operation.
This makes it suitable for monitoring vacuum while performing compatible automotive diagnostic procedures.
A correctly functioning gauge is particularly important when assessing whether a vacuum-operated component responds to applied vacuum or retains vacuum during a test.
The compact gauge diameter also makes it practical for use on a portable hand-operated pump.
0-30 inHg / 0-100 kPa Vacuum Measurement Range
The MVA6178 provides a vacuum measurement range of:
0-30 inches of mercury (inHg)
0-100 kilopascals (kPa), approximately
These scales allow users to read vacuum in commonly used imperial and metric units.
The inHg scale is widely used in automotive vacuum testing, while the kPa scale provides a convenient metric reference.
This makes the gauge useful when working with different vehicle service manuals and diagnostic procedures.
The gauge measures vacuum, not positive pressure.
It should not be confused with the compound vacuum and pressure gauges used on certain dual-function Mityvac hand pumps.
Diaphragm-Operated Measuring Mechanism
The MVA6178 incorporates a diaphragm-operated gauge mechanism.
This design is intended to provide reliable indication of the vacuum generated by a compatible Mityvac hand pump.
During operation, changes in applied vacuum are displayed on the gauge dial, allowing the technician to monitor the test.
A functioning vacuum gauge is useful for checking the response of vacuum-operated components and identifying changes in vacuum during diagnostic procedures.
For meaningful diagnostic results, always refer to the relevant vehicle or equipment manufacturer's specified test procedure and expected readings.
360° Rotating Gauge Stem
One of the principal features of the Mityvac MVA6178 is its specially designed 360° rotating mounting stem.
This allows the gauge to be repositioned around its mounting axis, helping the user select a convenient viewing angle.
The rotating design is particularly useful when the hand pump is being operated in confined spaces or from different working positions.
Rather than needing to reposition the entire pump to view the dial, the gauge can be rotated to improve visibility.
This feature adds convenience during routine automotive diagnostic and workshop maintenance tasks.
Convenient Pin-Release Removal
The MVA6178 also features a mounting stem designed for pin-release removal.
This allows the gauge to be detached from compatible Mityvac hand pumps when replacement or servicing is required.
The removable arrangement provides a practical way of replacing the gauge without automatically replacing the entire pump.
The gauge should be installed and removed using the appropriate procedure for the compatible pump model.
Avoid forcing the gauge or damaging the mounting components during replacement.
Replacement for Damaged or Faulty Gauges
A vacuum gauge may require replacement if it becomes damaged or no longer provides dependable readings.
Potential reasons for replacing a gauge include:
- Damaged or unreadable dial
- Broken gauge lens or housing
- Needle movement that is inconsistent or unresponsive
- Vacuum readings that appear incorrect
- Damage to the original gauge mounting assembly
- General replacement during hand pump servicing
The MVA6178 offers a dedicated replacement option for compatible Mityvac equipment.
Before replacing the gauge, it is advisable to check that the underlying fault is not caused by a leaking hose, damaged pump seal or another component of the vacuum system.
Suitable for Compatible Mityvac Pumps Without a Gauge
In addition to replacing an existing gauge, the MVA6178 can be used as an additional gauge option for certain compatible Mityvac hand pumps originally supplied without one.
This allows a suitable pump to be equipped with a vacuum measurement dial where the necessary gauge mounting arrangement is present.
Compatibility should be confirmed before purchase, particularly for pumps other than the MV8010 Selectline model.
Not every Mityvac pump uses the same gauge attachment system.
