Single (PG) and Multiple (MHM and MHC) Feedthroughs : Product data sheet No 101 (MPG/PG)0 pages
Data Sheet No : 101
nnPRODUCT DESCRIPTION nnSingle Probe Feedthrough Assembly
nnThe MPG/PG series of feedthroughs will allow single probes/elements to pass through an entry point into a vessel. The method of sealing is based upon soft sealant technology which employs various materials, selected according to the process conditions and media that will be met. When applying torque to the cap nut, the follower is forced to move in a longitudi-nal direction. This in turn forces the sealant against an internal seat machined into the bore of the gland body. The resultant force causes the sealant to de-form and close down on the probe/element and ex-pand into the bore of the body producing a pressure/vacuum barrier. With the exception of Lava and Gra-foil, the other sealants are re-usable. Applications : thermocouples, RTDΒs, analytical probes, sensor elements, capillary tubes. Product code : MPG/PG
