1 Pcs 40mm Vacuum Pressure Gauge BSP 1/8" -1~0 Bar -14~0 Psi with 3 Pieces Bushing 1/8" to 1/4", 1/8" to 3/8" and 1/8" to 1/2" and One Teflon Tape, Radial

The **Innfeeltech 1 Pcs 50mm Vacuum Pressure Gauge** is a compact, straightforward, and budget-friendly tool designed to measure vacuum levels in a variety of systems, such as HVAC systems, automotive engines, and laboratory equipment. Below is a detailed review of this product, covering its features, performance, pros, and cons.### Key Features- **Size**: The gauge has a **50mm (2-inch) dial face**, which is compact yet clear enough for easy reading.- **Measurement Range**: It measures vacuum pressure from **-30 inHg (inches of mercury)** to 0 psi. This range is suitable for most automotive and HVAC applications.- **Build Quality**: Made of stainless steel, the gauge is designed for durability and resistance to corrosion. It features a clear glass lens and a brass connection port.- **Connection Type**: The gauge typically comes with a **1/4" NPT male thread**, which is standard for many systems, making it compatible with most fittings.- **Analog Display**: The analog dial is straightforward, with clearly marked increments, making it easy to read even for those not accustomed to digital displays.### Performance and Ease of Use- **Accuracy**: This gauge is fairly accurate for general use, though it's not laboratory-grade. It's reliable enough for automotive diagnostics, vacuum pumps, and HVAC troubleshooting.- **Ease of Installation**: The 1/4" NPT connection makes it quick to attach to compatible systems. Users report that it screws in securely without leaks, especially when using thread sealant.- **Readability**: The 50mm face is compact, but the clear markings and black-on-white contrast ensure that readings are easily visible.### Pros- **Affordable**: Provides good value for the price, especially for non-critical or DIY applications.- **Durable Construction**: The stainless steel casing and glass lens offer resistance to wear, corrosion, and impact.- **Easy to Install and Use**: Standard 1/4" NPT fitting allows for compatibility with various setups.- **Accurate Enough for Basic Needs**: Suitable for automotive, HVAC, and home vacuum systems.### Cons- **Not Laboratory-Grade**: The accuracy may not be sufficient for precision applications. It's best for general diagnostics rather than scientific measurements.- **Analog Display**: Lacks the precision and features of digital vacuum gauges, such as decimal readings or backlighting for low-light conditions.- **No Protective Cover**: The glass face is exposed and could potentially crack if dropped or mishandled.- **Limited Range**: The -30 to 0 inHg range is typical for vacuum systems, but if you need a gauge for positive pressure, you'll need a different model.### Best Use Cases- **Automotive Diagnostics**: Useful for measuring engine vacuum to diagnose issues like intake leaks or checking vacuum-operated components.- **HVAC Systems**: Can help monitor vacuum levels during system evacuation or when testing pumps.- **General Household Vacuum Systems**: Great for troubleshooting vacuum pumps and similar equipment in home workshops.### Bottom LineThe **Innfeeltech 50mm Vacuum Pressure Gauge** is a solid choice if you're looking for an affordable, durable, and easy-to-use gauge for automotive or HVAC diagnostics. It’s a reliable tool for those who need a basic vacuum measurement device but may fall short for high-precision applications.

I bought this gauge for checking Air PSI on busses EBS and air suspension, it’s a lot smaller than I expected, then I re read the ad, that aside its size is actually a bonus, not much extra weight to carry round, all in all a very robust, well made item, I’d possibly go for the 60mm one if I purchased another

As a homebrewer, keeping track of pressure is crucial. This gauge is simple, accurate, and easy to read. It's also built to last. The included bushings make it compatible with different setups, which is a bonus. If you're looking for a reliable and affordable pressure gauge, this is a solid choice.

This was a good purchase as It was recommended by a friend. Fluid filled stopped vibration and very easy to install. Looks good when fitted on my RO unit.

Easy to fit and good quality.Fitted to engine and so far so good.No issues and seems to be reliable.

We haven't fitted this yet but the gauge appears well made and comes with a large roll of tape.It comes with 3 adaptors which is helpful.

I ordered this item and made an error in not noticing the size of the gauge. The gauge itself was a reasonable quality although smaller than I was wanting through no fault of the supplier. The adapters and PTFE however do not match the quality of the pressure gauge

The pressure gauge and the various threaded adapters arrived nicely protected with bubble wrap and packed into a plain cardboard box, which was then tucked into a grip-seal plastic bag alongside a surprisingly large roll of PTFE tape. I have no complaints with the packaging, and everything arrived in pristine condition and ready for use on whatever project you have in mind.I’m currently working on implementing a built-in air compressor for my hobby workbench and this felt like a good fit for adding a desktop mounted pressure gauge on the quick-disconnect air-line so I don't have to squeeze under the desk every time I want to check the psi. A couple wrappings of the provided PTFE tape and a few spins with a wrench is all this needed and it was giving readings as expected without any issues or leaks. I haven’t quite finished mocking everything up for the final install, but this gauge has been performing well for several test runs in-line with my airbrush setup.For my application the 0-100 psi limit of this gauge is several times over what I require for airbrushing minis and models as I very rarely need to go over 30 psi. The reading on this does match up with what the built-in gauge on my regulator shows, so it seems more than accurate enough for the job. Just for the sake of testing it a bit closer to the limit, I put my compressor up to 70 psi and the gauge had no issues keeping up with it.The price at £14.99 is maybe the only slight negative, as there are alternatives readily available for under a tenner. Otherwise, this is a good quality product and well worth considering if you need an accurate and low pressure capable pressure gauge suitable for a range of BSP thread sizes.

Semble robuste. Il est bien fini. Tout était parfait avec les raccords pour pouvoir brancher dans tous les cas de figures

Einwandfreies Gerät. Anzeige genau und einer der Adapter passte genau.

Todo perfecto
