Stirling Connectors
Normally I buy 50 bags at a time. I only live about 15 mile away from them so I pick them up. Not suprised you have seen them for much more... they are really high quality fittings.
Those connectors are Stirling wanna be's... I choose the real stirling cons which I or you for that matter can buy direct from them for 19 bucks a bag of 100. www.stirlingconnectors.com. I have used the aspen connectors and they just aren't the same as the original.
