    First time posting, lurking for a few years

    It's an industry non-standard o-ring conspiracy. Welcome to the diy frustration of working on your airguns, compressor, and filters.

    Bonded Sealing Washers (Dowty Seals) for GX CS4 Replacement/Substitute

    Possibly, would prefer more detailed specs though. The GX compressors can go to 5600psi and connected to the cylinder head they'd need to withstand moderate heat. Maybe if in the UK, and couldn't find anything with more specs. Shipping and tariffs to the US right now wouldn't be practical...

    Bonded Sealing Washers (Dowty Seals) for GX CS4 Replacement/Substitute

    While these aren't an exact match for the OME bonded sealing washer, they're just closest I could find without contacting GX. Replaced both on the banjo fitting where one came apart after my cylinder service. Dead head tested 4500psi, then topped off 6.8L tank to 4500. No leaks filling or held...

    AEA Queries for AEA challenger elite owners

    I got a .457 Challenger Elite shortly after the came out as my first air gun. The grove diameter slugged around .461. I cast my own with NOE 460-315 mold. Also have had a mold shaved off .050, and shortened pin to restore stability, drops 270gn. (Neither fits in mags) Mine perfered sizing slugs...

    Issues with brand new GX CS4 compressor

    Simply tell them you wouldn't have a clue as to what you'd be looking at, or for. Even if you have the mechanical ability I'd play dumb. Seems like they're trying to do the same thing. It's their warranty, it's new and not working properly, therefore it's their responsibility to fix it. You...

    Nickel, Dime, Dollars 😂

    Just in from work. 94's outside, 70% humidity. Clock on wall says 87 degrees in living room. But with ceiling fans, and mountain breeze thru windows it's not bad. Plus my electric bill stays below $100 a month year round. Work with guys that say theirs running 300+ right now. I'd rather spend...

    CS4i? Is there an issue?

    I had a poor crimped connector on the negative wire where diode jumps the wires. Ran fine, didn't notice it until wiring in a hour meter. Crimp is a stranded wire and solid wire into same connector. Solid wire can prevent crimpers from compressing the connector completely. I have good crimpers...

    One way valve for filling scba tanks.

    It will hold air indefinitely, just like an air gun, so long as there isn't an o-ring leak. Would take more $$ to install a gauge into the setup to know what psi it's stored at, but it's never kept near burst disk rating. Whether filling to 250 or 310bar, I simply bleed some to clear any...

    GX CS4 100hrs Cylinder Pulled, Was it Worth It

    Just did a 6.8 cylinder top off from about 245 to 310bar. Took 55 minutes straight run. Head temp reached 120F and water 110F (Ambient 75F). Thought I'd run cooler, then dummy me realized without the outer case on the fan isn't pulling air around the cylinder. So need a long run with it on for...

    GX CS4 100hrs Cylinder Pulled, Was it Worth It

    Around 28 seconds. This really wasn't worth the effort since everything was working. What's 3 or 4 seconds. Well know the saying, "If it isn't broke, don't fix it." Curiosity got the better is all I can say. Hopefully clean up will get me another 100hrs+. If so that's probably another 2yrs+...

    GX CS4 100hrs Cylinder Pulled, Was it Worth It

    Apologies for a long one I'm assuming that it hasn't been just me watching the hour meter climb and wondering whether, "Have I been greasing enough, or over greasing?" Or, "Does my connecting rod still have grease?" Well I figured I'd find out since no one has post anything about a long term PM...

    Nickel, Dime, Dollars 😂

    Back woods living has it's perks. Can start mowing my grass at 5am on a Sunday morning and no one around to complain. Could shoot out my windows if it didn't bother my dogs... maybe wife also. Get a big bore and start casting your own slugs. That opens another hole. Lead pot, PID controller for...

    Nickel, Dime, Dollars 😂

    Honey I only want pellet gun and a compressor. Well ok. 18 months later I getting the look :cautious:. Still shoveling the hole deeper. Today picked an A/C unit for the upstairs room. My family's 100+ year old house never has had A/C, but I need one now for my gun room to control humidity...

    Issues with brand new GX CS4 compressor

    I'm certainly not an expert or know all on the GX4 compressors, far more knowledgeable people on the forums than me. Have had mine 18 months and just hit 100hrs. I've read everything on here I can about them, satisfactions, disappointments, mods, ect. And still reading. My understanding is that...

Still dead head test within a few seconds of new. Per others here, I added tad of Purple Ice, some use...

    moisture prevention for GX-E-CS2

    You can find a multitude of threads here about moisture control, and filtration methods. We all have to deal with it. Environmental factors will greatly impact your personal needs. I'm often dealing with 50-80% humidity so my filtration needs are greater than someone in an less humid...

    Stoeger Updated Warranty Replacement for XM1 Bullshark Arrived From Benelli Today

    Mine has the plastic valve, didn't think to measure it. Hammer Spring is the weak link it seems. If I turn reg up even another .25mm (using measurement of entire reg length when adjusting) the fps drops. Also turning down .25mm and fps drops. Never found a setting where backing off hammer spring...

    GX-E-5K1 Compressor issues

    My GX CS4 says 99.3hr, probably 100 since ran some before installing meter. Lots of direct filling a big bore at the range, and plenty of top offs on 6.8 liter tank (3000 to 4500psi) Not a single issue. Planning to do a tear down inspection and preventative maintenance service this weekend. Will...
