CTI 98mm O-Rings

I'll be headed to the IREC 2017 next week with my university rocketry team. We'll be flying an AT M1419 reload in a CTI 98mm 3G case. I know that the official certification of AT 98mm reloads in CTI hardware may still be in the works, but they should be functionally compatible. Cesaroni has stated that the only incompatibility would be the O-Rings supplied by AT. Would anyone know the specs of the CTI O-rings required so they could be purchased separately or have experience with using AT reloads in CTI 98mm hardware? Any help would be greatly appreciated!

This might help....but then again you may only need the 0-rings that come with the M1419 (?)

-237 for closures, -137 for the nozzle housing. The -339 are required for ProX reloads in RMS hardware.

You'll need a 98mm forward seal disc...
The reload length should be right. Just make sure you feel the O-rings compressing while tightening the closures.

what team are you with?
