Crosman Challenger 2009 Pressure Gauge Change – Vital Information For Owners!

In this post, we cover the Crosman Challenger 2009 pressure gauge change and its implications. Also covered are the changes as they apply to Crosman and Benjamin PCP pistols.

The reason for the Crosman Challenger 2009 pressure gauge change – and that for the pistols – is exactly the same as already covered in HAM for the Marauder air rifle. Velocity Outdoor – the owner of both Crosman and Benjamin brands – decided to change from tapered threads on the gauge to parallel (or straight) threads.

The reason for this pressure gauge change was to further reduce the potential for leakage of High Pressure Air from the gauge threads. The “old” tapered thread gauges are installed using tape on the threads to eliminate leaks. Straight thread gauges – in comparison – do not use sealing tape but have an elastomer seal.

This manufacturing change was implemented in approximately November 2020.

Why Is This Different To The Marauder Rifle Change?

Although the change to the gauges used on the Challenger 2009 and the pistols is exactly the same as for the Marauder, Fortitude and Maximus air rifles, there’s a difference in how the pressure gauge fits into the gun.

In the models covered in our previous post, the gauge is attached to a Gauge Adapter. The Gauge Adapter is then attached to the Gauge Port inside the HPA tube.

In the Challenger and Benjamin/Crosman PCP air pistols, the gauge is attached directly to the Gauge Port. There is no Gauge Adapter in these airguns.

In principal, this sounds as if replacing a defective gauge on a Challenger 2009 or Crosman/Benjamin PCP pistol would be simpler, as less parts are involved. However, that’s not the case 🙁

Now, in order to replace a pressure gauge, the Gauge Port also has to be replaced. This means that the Fill Nozzle has to be removed and the “old” Gauge Port removed through the front of the HPA tube.

Making a leak-free installation of the new Gauge Port will be greatly aided by using the Archer Airguns Gauge Port Filler Tool For Benjamin Discovery Air Rifles. (All these guns have the same diameter HPA Tube as the Discovery). Photo below.

This Gauge Port Filler Tool helps ensure that The Gauge Port O ring is not cut during reassembly. You simply hold it in place in the gauge port hole in the main tube during reassembly. It stops the O ring from swelling out into the hole and then being cut as it passes back into the pressure tube.

You’ll probably also need to replace the Fill Nozzle O ring on re-installation to prevent the chance of a leak here. Again, Archer Airguns has parts kits…

So – in future – you’ll need a new gauge PLUS Gauge Adapter if you need to replace a defective pressure gauge in a Crosman Challenger 2009 air rifle manufactured prior to approximately November 2020. The old parts have been discontinued and are no longer available.

SAFETY FIRST: As with any work on any PCP airgun, before starting it’s vital to first ensure that the gun is clear, has no pellet in the barrel, is on safe and that no High Pressure Air remains in the gun. If you have any concern about de-gassing the gun, or any other aspect of safety, DO NOT START WORK!
