Guys I need a way to screw together short sections of 1/2" or 3/4" SS instrument tubing, each section being 4' long or so, and subject to the following constraints:
1) The OD of the coupling or connector must be the same OD as the tubing, i.e. a standard pipe coupling or pipe collar won't work
2) The ID must be open to pass liquid
An example would be the way that a rifle cleaning rod screws together - it has a smooth and flush OD at the coupling. These are not hollow though so the example stops there.
The coupling must be the same OD as the tubing because the entire assembly must pass through a packing gland. Do any of you know if a coupling/connector like that is commercially available? The Swagelok people were no help.
Thanks!
Pete
