These all-new multiconductor feedthroughs are designed for applications that require several sensors to pass through a wall or bulkhead at one opening or within a small area. Heavy-duty 416 SS construction allows use of this fitting in high-pressure or vacuum applications. Probes between 0.040" and 1/4" in diameter can be used in these feedthroughs. The maximum number of probes per feedthrough is 3 for 1/4" diameter probes, 5 for 3/16" diameter, 8 for 1/8" diameter, 16 for 1/16" diameter, and 16 for 0.040" diameter probes.

All multiconductor feedthroughs come standard with stainless steel ferrules. A stainless steel ferrule deforms and becomes permanent. If the probes have to be installed several times at different depths in the feedthrough, PTFE ferrules should be used. PTFE ferrules will not deform the probe sheath, which allows the same probe to be reused. The ferrules used in the feedthroughs are identical to the ferrules used in standard OMEGALOK compression fittings.

What's the maximum allowable pressure for a MFT-M10-5 feedthrough @ 752°F?

Asked by: GT_Eng_MA
PRESSURE RATING ON THE MFT MULTICONDUCTOR FEEDTHROUGH IS 5,000 PSI USING 316 SS FERRULES ONLY. THREADS ARE FINE THREADS. Note; Fitting is designed to be mounted on the ambient condition side of chamber. Cap and ferrules will not be inside high temperature environment.
