FAQ

Can finger-tight column nut fittings replace my existing fittings?

31 Jul 2025

Yes, in most cases.  For Agilent and Thermo 1300/1310 and 1600/1610 GCs, exchange the OEM fitting for either Restek cat.# 22347 or 22348. For Shimadzu GCs, exchange the OEM fitting for Restek cat.# 27230. For older Thermo TRACE and Focus GCs and for converting Shimadzu GCs to a standard 1/16”-type ferrule, you can use Hot Swap column nut cat.# 27224, but first must install a new capillary adaptor.
