View Full Version : xpansion chamber thread size???

12-07-2010, 01:13 PM
Hello, first of all, I'm a new paintballer and new to the forums. If anyone has discussed this before, I apologize but have not found all the info I need. I have a spyder aggressive xt (which I bought used) and recently purchased a bob long expansion chamber. I have the stock adapter to the co2 tank. I was planning on buying either a new braided line or macroline, however, I noticed that the threadings on both the chamber and the co2 adapter are different. The chambers threading is fine, while the adapters is course. At this point, I'm pretty frustrated seeing as how I also just recently noticed the last owner used red loctite on the stock asa fitting, so thats causing me a headache. But yeah, I have looked for new fittings, but all the ones I see look course, can anyone help me identify the thread sizing and or better yet, a place where I can find these parts. Home depot does not have them and I checked macrolineguy.com today, however, it did not say what size the fittings were. Thank you all in advance for any help you may have for me, and sorry for the long post.

NOrmally Spyder threads are metric & the Bob Long will be 1/8-27 npt.

Email Sunny over at SundragonPPS (click here (http://www.sundragonpps.com/paintball_spps_contact_info.html)) and tell him you need 2ft of macroline, a standard macro fitting, and a metric macro fitting. You can also peruse his online store and find the items yourself: http://www.sundragonpps.com/paintball_air_acces.html

The fitting you want for the BL expansion chamber is simply called a 1/8" NPT straight (or 90*) macro fitting.
