After 6 orders over the past year I think I finally got all the cam locks for my e-herms, pumps, HLT, MLT, chiller and kettle. Depending on how your system is designed will depend on what you need. I thought I went through my system design from beginning to end and ordered what I thought I would need, NOT, I still ordered more. To be honest the "extra" parts I didn't use I have used in other places. Can you have to much stainless???
If you want my inventory:
F cam lock 13
female high flow barb 8
A cam locks 2
Keep in mind this doesn't include all the 9+ nipples, T's and 90's barbed/threaded. I'm with iijakii I've ordered from both Bargain fittings and Bobby multiple times.
