General Information EMP-4 High-Pure
THOMAFLUID®-pipe screw fittings are used for connecting pipes made of various materials such as metal, glass or plastic e.g. PA, PTFE or PVDF. This represents a considerable advantage of this kind of screwed fittings. The screw fitting is not limited to use with rigid pipes but also with flexible pipes or tubing. In this case, carrying brackets (items 22036 - 22054 and items 304902 - 304934) are required. THOMAFLUID®-PFA (perfluoroalkoxy) pipe screw fittings of the MULTIFIT®-EMP-series can be screwed into THOMAFLUID®-valves, cocks, and flowmeters of the MULTIFIT®-EMP-series.
The straight-cutted pipe is plugged into the screw fitting until stop. Tightening of the cap nut leads to compression of a cutting ring made of PEEK (polyether etherketone), thus sealing the connection between pipe and screw joint body by means of a sealing ring made of PTFE (polytetrafluoroethylene). If flexible tubing has have to be adapted using THOMAFLUID®-pipe screw fittings, first the carrying brackets have to be put in the flexible tubes. Afterwards, the fixed assembly is done by tightening the cap nut.
High-quality technical plastic for chemical apparatus and machine construction as well as electrical engineering
Chemical, thermal and dielectrical properties practically such as PTFE, but suitable for thermoplastic processing (welding, die casting, deep drawing). Lower medium diffusion, better transparency, larger hardness and better dimensional stability (lower tendency to cold flow) compared to PTFE.
Highest temperature resistance of all meltable fluorinated plastics
Very high dimensional stability in heat
Very high resistance to media
Very good pressure resistance
Low friction coefficient
Can be treated by autoclave (absolute sterile)
