Tubing sleeves and kits When working with capillary tubing (such as fused silica or PEEKsil™), it is often a challenge to connect these thin lines leak-free to standard ports. Tubing sleeves provide the solution by artificially increasing the outer diameter of the capillary tubing so it fits perfectly into standard 10-32 or 6-32 coned fitting systems.

Why choose sleeves? Minimal dead volume: Sleeves centre the tubing exactly in the port, which is crucial to prevent peak broadening in nano- and micro-LC.Flexibility: Because sleeves are not permanently attached to a ferrule, they adapt easily to different port depths.Easy identification: The handy colour coding lets you recognise the inner diameter of the sleeve at a glance.Sleeve OD Type and Material Fitting System and Port* Capillary Tubing ODs Pressure Limit** Fitting Part No. 0.025" MicroTight® (PEEK) MicroTight®, 6-32 C 70–520 µm 4,000 psi (276 bar) F-125 0.025" MicroTight® (PEEK) MicroTight®, 5/16-24 C 70–520 µm 4,000 psi (276 bar) F-172, P-416 1/16" NanoTight™ (FEP) NanoTight™, 10-32 C 70 µm–1 mm 4,000 psi (276 bar) F-333N 1/16" NanoTight™ (FEP) Super Flangeless™, 6-32 FB 70 µm–1 mm 750 psi (52 bar) M-650, M-660 1/16" NanoTight™ (FEP) Super Flangeless™, 6-40 FB 70 µm–1 mm 750 psi (52 bar) M-650, M-644-03 1/16" NanoTight™ (FEP) TinyTight™, 6-40 FB 70 µm–1 mm 600 psi (41 bar) M-647, M-644-03 1/16" NanoTight™ (FEP) Alt.
