Pressure Gauge/Indicator - HuMa 23mm 250bar
This is a 250bar button gauge/pressure indicator. It is a great option for people who have faulty/leaking/damaged pressure gauges on their rifles.
The face is 23mm in diameter (21mm across the flats), the threaded section is 1/8" BSP and around 8-9mm long. As the name implies, they are pressure indicators and not 100% accurate, similar to a fuel gauge in a car.
These will work as a replacement gauge for a lot of rifles that have gauges as standard like the BSA Ultra SE, R-10, Scorpion SE, Air Arms rifles, FX and some Tench and XTX gauges, EDgun Leshiy etc. Please measure your gauge though because some gauges are 23mm, some are 25mm and others are 28mm, so they may not fit your rifle if it currently has a different size gauge fitted.
They are HuMa Air branded and have a white face.
