FX How many rings…..

[Mlydon]

How many o rings are SUPPOSED to be on an Fx liner. At what spacing, and what size are they?

I just swapped liners on my 700 .22 impact - there where only two o rings…. And I’ve seen videos of guys pulling 3-4 out when changing out.

I would think the more there are, the more stable the liner would be - but I could be all wrong

Thanks in advance,

Matt

Gut feeling is, a few. They just keep the shroud off of the liner. If you use a carbon fiber sleeve for the soda straw you don't use 0-rings. Won't hurt to have a few extras, give it a try and see what happens.

Want to say 3 but I’ve seen many on YouTube use none with no noticeable difference.

Probably depends on barrel length. My 500mm came with 2 o rings on it. I did have to use tape to keep them exactly where I wanted them while inserting into the gun. I have a carbon sleeve on the way from Utah Airguns that I’m going to try out as soon as it gets here also. Replaces the o-rings entirely.

Like usual FX throws on whatever they have on the bench, 1-4. My Mav had 2 600mm. Get a CF sleeve, easier to install with it and they are cheap.

Using CF liners is a placebo, especially for those who bonded to the liner.
I have tried and back to orings.
From my engineering point of view if you research what the "node points" means on tubes - hollow or solid. Every rod/tube round or square has two node points=static non oscillating. Start tinkering from there.
All my liners I overdo the orings, spaced on 10cm along the length.... more won't hurt. Also, the OEM orings were NBR70 I replaced with NBR90, staying firmer even at high ambient Temp. Also replaced the barrel holding orings in the blocks as well.

Bighun - what size are they?

My Maverick came with 2 I changed them out for the carbon sleave. My M3 I bought used had 3, both are 600mm

5.23mmx2.62mm. I’m going to say there should be 3 in there from the FX drawing.

I have a 600 mav, with the CF bonded zippo issues, the 500 mav has the liner floating, it was a snug/slip fit, it also is working fine.

Bighun - Thank you - I found that diagram earlier today, have a 100 70’s and 50 90’s inbound from oringsandmore.com. Cost a whopping 3 bucks….
