Outer Limits 4x4 Board

Doing my front locker seals today and am a lil' stuck on what seals I need as the locker is leaking air into the diff housing. It's not engaging the front locker, i.e. compressor keeps cycling every 20 secs when I hit the fr locker button and diff housing pressurises while I hold my thumb over the breather.
Long story short, is there a need to go genuine arb seals or are they an 'o' ring style seal that I can get from a bearing shop or ripco?
If they're generic, does anyone know what size they are? I'd guess it's just the one on the inlet rather than the piston seal- as they've hardly been given a hard time or used much. Thanks in advance for any advice.

from memory there are orings in the end caps for ur bearings they are mostprobably the ones leaking. as for sizes no idea and good luck finding them today

they are viton o-rings not the normal nytrile type

Thanks fellas, yeah, good luck finding em today- I know
I'll make sure they're the viton ones if I do

Should I just get the Arb seals or is it significantly cheaper to get aftermarket ones, as long as they last the distance?

all viton seals should be as good as each other

How long since the locker was put in?
ARB will fix it if it's under 2 years.

It's about 3 years unfortunatley, ARB didn't fit them, I had a 4wd workshop do it when the zook was being built.
It would be very nice if they would fix it
Might be worth asking the question aye!

they are about $150 each from arb.. stop being a tight arse

nah seriously just easier to get from them

i think its bs136 or bs138 for the vits.

sorry $1.50.. cheeky little "."

Cheers bigcam, I had a lil' chat with a few guys today from Arb Kilsyth and they gave me the run down on why and how it could've failed and all the various seal types it could be...
Think I'll just pull the center out myself, not so hard (fingers crossed ) and take it to a 4wd mech who I trust already to do the the fidly stuff with the diff. I don't really feel like doing the same operation 2 or 3 times over if I stuff it up, just for the right to say "I did it myself".
