An FEP lined, stainless steel tube is swaged over multiple, insulated, single-core copper and/or thermocouple material wires to make a continuous wire, high-density, sealed feedthrough tube with up to 60 wires. These are used for thermocouples, resistance thermometers and low voltage instrumentation. The sealed tube assembly is usually mounted in a Series PF or MF feedthrough. Series HF feedthroughs are manufactured with customer-specified wire lengths.

Epoxies and other sealants are not used in the construction of HF feedthroughs. sealed tubes. They are suitable for use where outgassing is not permitted. The thermocouple pairs are available with or without junctions. Please contact us for further details.

Single tube assembly mounts in a series PF or PSF feedthrough, sold separately
Multiple tubes mount in a series MF or MSF feedthrough, sold separately
Saves time and costs by allowing multiple sensor wires to pass through a feedthrough as a single element
Sealed tubes with continuous, multiple, insulated conductors
Stainless steel tube (316L) is sealed without potting, epoxies or glues
