My marauder slowly leaks air. Any reason or repair at home. or should it be sent back. I always leave gun charged with air
My marauder slowly leaks
- Thread starter TROP
- Start date
I'd repair at home, myself. Particularly if it was a shooter. Never know what you'll get back from the factory or dealer. If you haven't opened one up, don't be intimidated. They're a piece of cake to fix.
Edited to add: Once you find the leak.

You can put a balloon over the end of the barrel I usually just use a rubber glove make sure it’s sealed and see if there is any air in it in the morning. If so I it’s probably your valve poppit. It could just be a little bit of debris that needs to be wiped out. Before you start tearing it down, try to find a new ring kit Airgun. You can search for captain O-ring online. Careful about learning how to work on your marauder it’s a rabbit hole of fun and all sorts of aftermarket parts and information.

Take another balloon and put it over the fill port. That is always a likely culprit and super easy to fix.

I would add besides lubing the o rings use caution when pushing them past the openings in your tube as the sharp edges can cut the o ring. I push them down with my finger as they enter these areas

Over time o-rings can loose their elasticity and need changed out. If you are mechanically inclined, there's plenty of places to get the Marauder o-ring kit from, including directly from Crosman/Benjamin parts department. You could also make a post here to find a member close by you that is willing to help.

I recently had a very slow leak on my Prod which is similar in build to a Marauder and it was the check valve in the foster fill...polyurethane o'rings purchased at amazon I think from Capatin O'ring, just search for Marauder check valve o'ring. But, it could be something else like the poppet or...just an fyi.

My marauder did that twice. Both times in the same place. Below is the link to a very helpful video to fix what I believe may be the most common leak point for a marauder.

I had a very slow leak on mine when I got it. I sprayed soapy water to find very tiny bubbles coming from the threads of the foster fitting. I tried to reseal with Teflon tape, but it still leaked. I eventually stopped the leak by sealing the threads using Loctite 545. Its for high pressure hydraulics and pneumatics.

Crosman changed the thread types last year or so, one is tapered and not compatible with the older type, so be mindful with the gauges, blocks, orings and tape.
How old is the Mrod and how slow a leak?
What’s your air fill source? ( hand pump, compressor, scuba shop, etc) How long was it without a leak? theres only the fill adapter, gauge, gauge block o-rings, valve orings and stem to leak. An overnight balloon over the fill adapter and bare barrel will rule out a stem or fill adapter. After that its either the gauge threads or a block or valve o ring. Both or one of which might leak again when you replace it unless you deburr the holes.

Archer sells a real nice gauge port tool. It helps to not damage the orings when you install the valve and gauge blocks. Get some 1/2 inch PVC pipe, it works great to push everything out of the tube.

Buongiorno, sono Luca da Verona (Italia) e sono nuovo del forum. Ho anche il problema dello sfiato del Marauder attraverso il nipplo di riempimento. Vorrei solo che mi dicessi gentilmente la dimensione corretta dell'o-ring del capezzolo Crosman 1761-106 e di che materiale è fatto, poiché Crosman non lo fornisce in sostituzione e proverei a cercarlo qui in Italia se può....

That is a part that you will have to disassemble to discover the answer. Disassemble the fill nipple then measure the old o-ring and match it to the correct size.
Alternatively, you can call Crosman to possibly get the correct o-ring and or replacement part.

I agree with bearair. I had a Huma regulator in and out of my Marauder at least four times before getting it set where I wanted. Archer Airguns gauge port tool proved its worth to me.
