General description

Nuts and ferrules included.

Reducing unions of Swagelok® type are mostly used as metal column terminators. All original reducing unions have a bore in the centre of about 6mm in length and an internal diameter of 1.2mm. Moreover, reducing unions have a large bore at the non-reducing site. Modification is necessary in reducing union in order to minimize peak broadening, pressure resistance and to ease the installation process.


Brass Swagelok® reducing union may be used for providing connections for the glass tubing fitted in it to the stainless steel tubing by means of PTFE ferrules, in an elution technique used for the determination of solubility of gases like argon, helium, nitrogen and carbon dioxide in molten salts at pressures ranging between 0.5 to 2atm.
