I have to finish my t-shirt launcher TONIGHT and have a question about the o-ring i have in the back of the tee- this bushing will slide into the back and will be bolted into the tee so i can open it up for maintenance.
What i'm wondering is if the o-ring is too far down in the slot and won't form a good seal, so i need a reply fast.
Thanks

looks to me that is it too far in. it needs to extend to a larger diameter than that of your bushing. If not, it won't contact to socket your inserting it into and create a seal.

I think your groove is too deep.
As it's going to be bolted in, you could try it as is first.
You might be able to fix it by putting several wraps of teflon tape in the groove under the o-ring.
Good luck.

I kindof have a question pertaining to this:
If the o ring is too big, (like in a o-ring grooved piston), how does it fit in the housing? (I encountered this problem alot with my o-ring attempted pistons).

I've heard of lithium grease as being particularly good.
