Hi Reedmosser, I agree it must be a Chinese booster. It would have to be at this low price. I can't find a trademark or any mfg ID anywhere on it. Speaking of Chinese companies, I'm in the market for a home shop air compressor and I have been looking at one of the few American made ones out...

SqrlHntr, I reached out to Extreme Big Bore and asked for advice on adding a pressure gauge. here was their response: "I would not recommend that as this will void your warranty. Also, we can not guarantee the performance of the Booster Pump". My next question was on how to fill a gun...

I finally completed the modifications to my "Extreme Booster Pump" and now I'm satisfied with how it performs. I added a check valve to the high pressure output. Now I no longer have a pressure drop during piston return and the gauge holds steady and easy to read. I also added a metering valve...

Brass is used in a lot of high pressure applications. The pressure capability depends a lot on the part geometry and quality, not just the material. Look at the massive wall thickness of that pressure gauge fitting. This thread is mainly about the more fragile quick disconnect fittings and the...

I buy my air hose and QD fittings from Air Tanks Plus. They have very good quality.

I had my name on an M3 waiting list for a couple of months. Then thanks to a tip on this forum I learned that Bullet Cantral had what I wanted in stock. If I had done my legwork and checked with all the FX dealers, I would have known that. Check around and maybe you can find what you want.

Beware, there are a lot of foster quick disconnect fittings selling on Amazon which are of unknown origin and questionable quality. Here is one particular seller that has several errors in the product description which makes me believe it is all BS. The Amazon seller is IORMAN. I suspect the...

Motorhead, I purchased my extended foster fitting, the one with the missing ball, from Utah Airguns. It is listed under FX accessories. The body is brass and their website states that it is rated for a max pressure of 4500 psi. I don't believe it. I think these pressure ratings are just made up.

Very good information !!! After I read the article I started checking my fittings and discovered a missing ball on the new extended quick disconnect I just purchased for my FX. Also, after seeing a photo of a brass female quick disconnect that burst (stainless outer ring, balance brass), I...

Allen, I'm aware of that, though I'm not above making such stupid mistakes.

Chickenthief, Thanks for your input. You're right, I have been overthinking it. What it really comes down to is pretty simple, with a little more understanding of how this pump works. I found a little more information. The big drop in air pressure is the return stroke of the piston. Due to the...

The Altaros booster looks interesting and I wish I'd known about it earlier, but I already bought this Extreme booster. It seems to me I should be able to make this booster work. I've been studying it closely and it looks like there are the two problems with this pump. 1) When the the pump...

I recently took delivery on an "Extreme Booster Pump" and tried it out. The first problem I was faced with was no means of measuring the high pressure output. This booster doesn't come with a pressure gauge and neither does my "Western Big Bore Bushbuck" rifle. If I'm not mistaken, "Extreme Big...

I bought the Alkin W31 vertical 220V and don't regret it. It's a good compressor. For traveling I just carry a tank and an "Extreme booster".

Sorry I'm a bit late to comment but I'm glad the issue was worked out. It was not your place to file a claim with Fedex. You were not the shipper, the merchant was. This was totally the merchants responsibility to fix or replace the item. If the merchant had given you any hassle, you could have...
