Air Venturi Inline Air Pressure Gauge, 0 to 4500 psi

Small size. Allows confirmation of pressure in the line and tank during filling.

Tolerances on the foster connectors is lacking. When the hose is pressurized, it can cause a "hammering" effect, which can break one of the connectors (the female end).

This idea is excellent, however the fittings are not durable enough and quite loose before the line is pressurized. Mine split half of the female retaining ring off, so I can no longer use it, after around 15 uses. The only way to make this work reliably is to do the initial pressurizing of the line very, very slowly. If you don't, the "hammering" effect can cause the female fitting to break.

I needed an input gauge to my carbon fiber tank and this worked.

I would utilize the gauge service a little more an seperate the numbes a bit more.

WORKS PERFECT

NOTHING

This is usually more accurate than the gauge on the gun.

The gauge is accurate

the female fitting got sticky. Its kind of a pain to attach and detach.

Make sure the fittings are attached and locked in fully. If it can pop off, it will, with a bang!

Having an extra gauge to double check the pump gauge.

Make the gauge larger.

Worked very well.

Very well made.

It is too small and difficult to read. You must get too close to read it.

It is advertised as 0-4500 psi but the gauge dial is 0-6000 psi. This reduces accuracy. Be very careful if you must get close to read it. If something fails or pops lose you could get injured. Wear eye protection.

It does work and for those filler hoses that do not have gauges on them, this is one of the easiest options.

The writing on the gauge is much too small and the gradients (500PSI) are too difficult to use. The gauge only covers 1/4 of the whole face. Get a gauge that covers 2/3 of the face with 200psi increments and this will be a great product.

The gauge connects to your existing filler hose. It's actually quite small. The photo does not make that very clear.

It's a good design with quick disconnects on each end and the size & functionality are good.

Better QC is needed. Mine leaked at the gauge upon arrival making it unusable out of the box and to top it off the female QD fitting was too 'tight' and would not lock down. I really had to work it to get it on the first time but after making and breaking the connection a number of times it became much better and worked normally. I called PA's tech support, which is very good by the way, and was told to try using teflon tape on the pressure gauge but that didn't even work. it still leaked, just a bit less. A replacement is on the way.

Air Venturi needs to step up the QC of their HPA products to make me feel comfortable with them. Ill fitting connections and leaking products do not bode well in 4500 psi applications so I'm a bit leary at this point. I'll update or add another review upon receiving the replacement unit. Hopefully I just received a dud, which sometimes happens. PyramydAir gets 5's across the board for outstanding support and customer service so feel confident buying from them.

The idea of a small inline gauge.

The design of the female foster fitting. If Pyramyd offered a quality alternative, I would buy it.

The tiny ball bearings will fall out of the female foster fitting. Often. Poorly manufactured fitting. I've had two with the same problem. I'm always worried that one of those tiny bearings will fall right through the male foster on my gun and wreak havoc.

Helps with checking air pressure when refilling you PCP.

Very tight fit with the Foster fitting on my Marauder.
