Standard temperature range: -40oF to 200oF
Consult factory for quotations on feedthroughs outside this temperature range

Standard feedthroughs include NPT UNF/Facial "O" ring and ISO-KF stainless steel bodies utilizing our hermetic sealing system. This system does not rely on epoxy for sealing, but employs a swaged elastomer gland.

Solid or multistrand copper conductors are available in sizes from 28 to 12 gauge. Standard thermocouple wire calibrations are stocked in 24 gauge with others available on special order. Teflon installation is used unless otherwise specified. Up to 92 conductors are available in a single feedthrough, depending on fitting and wire sizes.
