MULTIFIT^®-cocks and valves for rigid tubing

With fine regulation, for controlled splitting of flow and reproducible, constant aliquot sampling

MULTIFIT^®-cocks and valves fix tubing (pipes) by means of a compressed FPM O-ring. The higher the internal pressure is, the tighter is the joint.

MULTIFIT^®-connections are closed and opened within seconds.

Size A:

For highly flexible PTFE tubing, with outside Ø 0.6 to 1.0 mm (1/32").

Size C:

For tubing used in many chromatography systems, with outside Ø 1.3 to 1.6 mm (1/16"). The cap nuts of size C and D have the same thread size. Therefore, the total versatile assortment of size D RCT^®-couplings, cocks, and columns can be coupled to the 1/16" tubes after changing the cap nut and the sealing ring.

Size D:

For 1/8" tubes of the THOMACHROM^®-chromatography system available in various materials and with inside diameters of 0.25 to 2.0 mm. Suitable for outside Ø 2.4 to 3.2 mm. The nuts of size D are marked with a notch.

Size E:

For 1/4" tubes and glass pipes of chromatography columns, suitable for outside Ø of 5.7 to 6.4 mm.

MULTIFIT^® are available as standard type with PVC-U nuts for aqueous and non-aggressive solvents, and as SR-type with nuts made of PCTFE for temperatures up to +120 °C. O-rings made of FFKM are available for particularly aggressive liquids such as pyridine, ketones, and esters (to request separately).
