Pressure and Vacuum FEEDTHRUs™

 


The PV-Seal™ brand of pressure and vacuum FEEDTHRUs™ will positively seal round, oval and spiral cross-section sensors (including thermocouples, RTDs, metal tubes and other sensor wire types) for pressures to 200 psia and vacuums to 10 microns. (An optional, high vacuum version is effective for vacuums down to one micron.)

The unique design features of these FEEDTHRUs™ eliminate all the problems associated with other sealing glands, cumbersome sandwiched double flanges and in-house potted seals. Our FEEDTHRUs™ do not develop leaks with handling and usage. Broken sensors are easy to remove and replace: simply loosen the pressure cap, pull out the old sensor, insert a new sensor and hand-tighten the pressure cap: the seal is restored.
