Wika mini pressure gauge, 28 mm diameter and wide 250 bar scale for the FX Impact


This original, high quality, 28 mm Wika mini pressure gauge, was the model for the cheaper copy of the FX Impact pressure gauge currently used on their brand new 2019 MKII rifles to indicate the fill pressure.
It can be used as an upgrade or a one on one replacement gauge for the FX Impact MKI and MKII gauge mounted at the side of the action. The gauge even fits the black MKII cover sleave.
Wika gauges are world wide famous for their quality and accuracy and are even used in precision medical equipment. It has a solid brass housing and a wide dial scale. 
The gauge comes with an o-ring what can replace the plastic washer what is under the factory pressure gauge. Due to this o-ring there is enough movement to line up the gauge perfectly in eye position.

For this 28 mm Wika pressure gauge we have an optional black tactical cover cap available to create the same look as the new model FX Impact MKII

For the indication of the regulator output pressure of your FX Impact we have the 23 mm pressure gauge. and the 23 mm black tactical covers also available. 



This is an universal pressure gauge what can be used on several airguns. Never exceed the factory advised fill pressure of your rifle.

Great company to do business with . Excellent products at reasonable pricing . Seems to be more accurate than stock . Can't wait to see how they are after some time . Looking forward to doing business with this company again .

Before the rifle is out the box I fit these.... no comparison, regularly find the FX gauges to be more than 10 barg inaccurate both above and below the actual pressures.

Very accurate it works and dose its job. Would I buy another yes...

Great product. Easy to change over and finally a gauge that's accurate. Shipping was super fast, less than a week to the US, was shocked when they showed up so fast. Thanks for the great service.

Regards, Ed

Huma I must say are one of the best companies I have dealt with, every thing was smooth and went well. Delivery was super fast. Products I had were super quantity.
I had two Wika 28mm gauges and covers for my mk11 FX impact
Thank you very much,

Looks good, accurate, better than the factory one.

Excellent bit of kit.

Nuno - 22-04-2020 23:14

good upgrade gauges.
used on impact mkII.

MarkLondon - 07-04-2020 06:03

Wow! These gauges are beautiful...They look even better when you open the box as opposed to seeing them on the website...They are clear and precise!
I put them on my FX Impact .30cal gun. My FX regulator read 15 Bar higher than the new Huma-Air regulator and my FX pressure gauge read 45 Bar higher than my new and improved, more accurate Huma-Air gauges... They work as promised and look really nice, and are so easy peasy to change out!
The only thing I would have liked to see different is a 250 Bar printed on the gauge instead of a longer line that indicates 250 Bar. Other than that I would definitely buy these gauges again...
They are a great bit of kit!
Cheers, Mark

I bought the wika gauges for my fx impact mk 2 the fx ones are based around the wika but the quality and accuracy is not the same if you want true accuracy buy the wika gauges from HUMA fast delivery

Excellent replacement gauge for fx impact x and excellent service

IOANNIS POLYZOIS - 27-07-2019 09:54

This little manometer is the absolute upgrade versus all other no name factory installed gauges(even if they have a name on them).
Robust,accurate,reliable, ideal for regulated pressure reading, when tuning a precise weapon...(if you have the extra space needed)
Wika is the name for serious air game!

Cobos - 05-07-2019 14:47

My FX Impact X 700mm gauges were way off .... excellent quality built with Huma

Dennis Oosthuizen - 27-06-2019 05:28

Very accurate and reliable, a perfect and necessary upgrade for a FX Impact. Easy and clear to read the gauge. Very good quality.
