Hello

Does anyone know where we can buy PTFE ferrules used on the gas lines 
of our Delta isotope instruments?
They are used for connecting 1/8" Swagelock fittings but have a 1/16" ID.
I have tried most of the chromatography suppliers but they do not 
keep this unusual size fitting.

Regards

John
