Features

  • Installing this adapter to your AirJavelin or similar air archery gun allows you to replace the CO2 tanks with the most common removable high-pressure air tanks
  • Air tank and regulator NOT included
  • Only use a HPA (high pressure air) regulator with a max pressure of 1,100 PSI
  • Intended only for use with the AirJavelin CO2 arrow air rifle
  • Includes a hammer spring specific to the AirJavelin CO2 air gun (CO2 not included. To ensure a proper seal and for best performance, Umarex-brand CO2 is recommended.)

Description

Saves your CO2 and saves you money by allowing you to remove 88g CO2 capsules from your airguns without venting the remaining air; Also allows you to use the same 88g CO2 capsule in different airguns. 88g CO2 capsules can be used for shorter sessions by simply removing the capsule with the adapter attached when you're finished shooting and use them together again later. Prevents o-ring and seal damage caused by leaving CO2 gas in an airgun for long durations. Solid aluminum construction with high-quality o-ring seals. NOTE: includes adapter only. CO2 NOT included.

    • It works Great in my Spyder Paintball gun !
Size: One Size Color: Multi
First thing I'm not being paid to do this review . After reading a bunch of reviews about this adapter I decided to get 2 . I tried one today and it performed flawless. One thing I did was buy adapters to convert to 88/90s . Never bought bottles. They allow you to use this adapter and save Co2. Without them I don't think you can use this item unless it's the same size thread size as the 88/90 bottle. I got JT adapters and they're fine. The thread count in the picture was I believe 5/6. When they arrived the count was 10 and good thing because that gives you plenty of thread so you don't bottom out and not pierce the Co2. This adapter saver has the male and female 88/90 threads. Make sure you put a little o ring oil on the o rings ,top of Co2 bottle and it won't hurt to put a little on smooth part of the bottle, approx. 1/4 in . if you look in side the adapter you will see the o ring and what I'm talking about. What I did was oil everything up ,screw the JT on first then this saver, I used pliers and a rag to to hold the JT and I hand screwed the saver in. Then I snugged the saver very slightly with a 1 in. wrench. Then the bottle by hand nice and snug . I hardly heard a sound. Now when your done just gently break the saver adaptor with the 1 in. wrench while holding the JT or whatever one you have with a rag and pliers. Then you unscrew by hand , you'll hear a little Co2 but not much. Hope this helps . ... show more

    • Perfect
Size: One Size Color: Multi
Fits perfectly and works great in my Umarex Javelin. Was waiting for this to get here before I used it and was worth it. Makes it possible to have short sessions without wasting and entire cartridge. 12 or 88.

    • Does NOT Work with Fusion 2!!!!
Size: One Size Color: Multi
Review Image by DT DT
I bought the Fusion 2 specifically because this adapter was supposed to work on it. You can clearly see in one of the pictures for this item that it says it works with Fusion 2. HA! IT DOES NOT WORK. Don't take my word for it, that is what Umarex told me when I sent my Fusion 2 and this adapter to them for repair since the adapter would not work on it. Umarex said that the adapter does not work with Fusion 2!! So now I'm screwed. I only wanted this rifle because I could use this saver with it, and it is to late to return the rifle. Thanks a lot for false advertising. ... show more

    • Nice adapter for the C02 Air Javelin ,held pressure overnight
Size: One Size Color: Black
Nice adapter, held pressure overnight...threads nice....put a little Super Lube Oring silicone on the Orings...worked great. One tiny complaint, the plastic rail ( On the gun ) it slides on is undersized...so it has a wiggle...screwed down. Just took 2 small strips of servo tape, put it on the adapter where it meets the plastic frame of the gun...no more wiggle whatsoever...easy and solid. ... show more

    • Great idea, but not for SIG CX
Size: One Size Color: Multi
Unfortunately I didn’t see the previous review warning that the product doesn’t work with the Sig Sauer MCX air rifle. Wasted money and a 90gr co2 cylinder.
