I have talked to a few customers this week who were having some trouble identifying the sizes of the ends for our Swagelok tube end reducers, so I thought I would write a post to clarify this information.<\/p>\n\n\n\n

A general photo of the style of a tube end reducer that we sell is shown below.  The Red<\/span><\/strong> Arrow points to the “tube” side, and the Green<\/span><\/strong> Arrow to the “compression” side.<\/p>\n\n\n\n

The table directly below lists our Swagelok tube end reducers.  The first dimension (left-side) is the outside diameter (OD) of the tube end (as shown by the Red<\/span><\/strong> Arrow above) and the second dimension (right-side) is the compression end (as shown by the Green<\/span><\/strong> Arrow above).  The compression end is listed as the size of the OD tubing it is designed to connect to.  For example, Restek 23179 has a 1<\/sup>\u20444<\/sub>\u2019\u2019 OD tube on one end, and the other side (compression end) will connect to 1<\/sup>\u20448<\/sub>\u2019\u2019 OD tubing.<\/p>\n\n\n\n

I hope this helps clarify the end sizes of our tube end reducers.  If you still have questions, email technical service .  Thanks.<\/p>\n\n\n\n
