O-rings for RA-Tech KSC Glock CO2 mags?

Stealth · June 20th, 2012, 09:46

Those of you who run these mags, did you notice the valve o-ring is incredibly easy to tear, thus resulting in leaky mags?

If so, what did you replace them with? I'm having a hard time matching the right size at Home Depot, then went to McMaster Carr last night and got a so-so match on one of their Silicon o-rings.

Curious to hear what others' findings are.

Go to Princess Auto or similar and get a box of assorted orings. I got one for like $15 or $20 and it includes many rings of about 40 different sizes.

EDIT: found the one I have. http://www.princessauto.com/pal/prod...-pc-O-Ring-Kit

Couldn't you buy ones made specifically by KSC or RA Tech? Or is it their o rings that are the issue?

AFAIK, neither KSC nor RA-Tech sell the o-rings separately, why? who knows.

Styrak, good idea, I shall grab a box of those if the ones I ordered from Mcmaster Carr don't work out. Although, methinks if I measured and matched using a digital caliper you'd think my choices would be good. The o-ring box kit would have just the standard sizes?

Did you find one in that box that worked for you? I'm referring to the main valve o-ring (the really thin one that seals the valve against the body of the mag)

There's some fairly small ones in there, I'm not sure if they're small enough though. How big?

K so... I actually nailed them with my McMaster Carr order.

Here are the part numbers (if anyone cares):
9396K15 - Silicone O-Ring, AS568A Dash Number 010 - this one is for the valve o-ring
9262K103 - Metric Buna-N O-Ring, 1 mm Width, 6 mm ID - this one is for the CO2 nozzle o-ring

The best part is that Silicone o-rings can be used as spacers for M4 hop-up units too.
