FMI-Connecting
Product specification
For coupling from tubing / pipes to FMI-pumps. Pressure resistance amounts to 3 bar at +20 °C.
The connecting bodies sitting directly on the cylinder sleeve are made of PTFE, cap nuts are made of PCTFE and the compression rings are made of FPM.
For fluids in which FPM swells, such as esters, O-rings made of FFKM are available.
General Information MULTIFIT®
MULTIFIT®-couplings 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 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.
The series 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).
Material:
Body: PTFE (Polytetrafluorethylen)
O-ring: FPM (Fluorkautschuk)
Max. operating pressure: 3 bar at +20 °C
