Sealing Gland Assemblies
STANDARD ASSEMBLIES
PACKING (PG) GLANDS
Conax Buffalo tube or probe sealing glands, for gas or liquid, are excellent for applications such as thermocouples, RTD's or thermistor probes, dial-type thermometers, etc. Easily assembled by simply inserting element and torquing cap. Resealable sealant allows repeated use of stainless steel fitting.
MIDLOCK (MK) GLANDS
These innovative tube or probe sealing glands feature a stainless steel ferrule assembly which may be opened and resealed. Ferrule is deformed against tube and makes a seal without cutting sheath surface. Easy to use by sliding assembled fitting over tube or probe and simply torquing at desired location. Applications include thermocouple probes, laboratory test lines, etc.
TRANSDUCER (TG) GLANDS
For bare wire sealing against gas or liquid, our TG Glands can be used for various solid bare wire transducers such as thermocouples, strain gauges, thermistors and resistance element leads. May also be used to seal bare solid conductors entering a pressure vessel supplying high current at low voltage to equipment within the vessel.
POWER LEAD (PL) GLANDS
Our insulated power lead sealing glands, for gas or liquid, provide versatility in applications such as autoclave, transformer, motor power, and sterilizer feedthroughs. Kapton® insulated wires with identification are easily assembled, positioned or replaced in field. Easy installation-requires no potting.
MULTI-HOLE CERAMIC (MHC) GLANDS
Conax Buffalo multiple tube or probe sealing glands provide the solution for applications such as multiple thermocouple, RTDs or thermistor probes, tube bundles, liquid level sensors, etc. Each immersion length is readily and independently adjustable. Selected elements can be individually and economically replaced.
MULTI-HOLE METAL (MHM) GLANDS
Conax Buffalo MHM multiple tube or probe sealing glands can be customized to accommodate special hole patterns, irregular shapes and higher density requirements for gradient thermocouples, RTDs or thermistor probes, tube bundles, liquid level sensors or other devices.
ELECTRODE (EG) GLANDS
Our electrode sealing glands, for gas or non-conductive liquid, are used in applications such as bare electrical feedthrough for vacuum furnaces, liquid level probes, transformers, reactors, environmental chamber power conductors, etc. Conductor is easily terminated in the field.
ELECTRODE GLAND TEFLON (EGT) GLANDS
These electrode sealing glands, for gas or non-conductive liquid, feature an electrode encompassed by a continuous Teflon® insulator/sealant. Applications include bare electrical feedthrough for vacuum furnaces, liquid level probes, transformers, reactors, environmental chamber power conductors, etc.
SPLIT PACKING (SPG) GLANDS
Conax Buffalo split glands for single or multiple probes are used wherever the probe cannot be installed through the sealant, either because of length or stepped outside diameter. When probe maintenance is required, sealants are easily replaced.
FIBER OPTIC GLANDS FOR SEALING ON FIBER OPTIC CABLES
Available with connector terminations: ST, SMA, FC. Standard fiber core sizes available: 8.3, 62.5, 100, 200 & 400 micron. Adaptable to customer supplied fiber. Capable of sealing outside jacket diameters of 400 to 1040 microns.

Proven rugged design technology. Fiber optic cable is protected inside sheath. Seals without the use of epoxies. Low out-gassing materials. Adaptable to special applications.
Helium Leak Rate: 1x10-6sec/sec typical
Transmission Loss: Less than 0.3db typical (not including connectors)
Pressure Rating: 1000 PSI (70 bar)(standard)
Temperature Rating: -58°F to +185°F (-50°C to +85°C)
CUSTOM ASSEMBLIES
VARIABLE DIVERSE MOUNTING
All Conax Buffalo sealing glands can be customized for 0-ring, tube flare or flange mount. This mounting diversity enables our engineers to easily adapt proven sealing techniques to your process equipment requirements for pressure or vacuum applications.
WELD NECK MOUNT
All sealing gland styles are available in direct weld mounting designs. Weld mounting is often desirable for high vacuum applications or when thread-free configurations are required. The weld neck designs shown can be longer or shorter, and the diameter and material can be changed to meet your specific application requirements.
QUICK MOUNT COUPLER
QM Couplers provide a quick and positive method of removing and resealing multiple wires and probes. They also eliminate the twisting or entangling of long leadwires caused by rotation while screwing a fitting into place. Depending on the quick mount coupler and sealing gland you select, assemblies can be installed in pressure applications up to 6,000 psi.
HIGH PRESSURE SERIES Our in-depth sealing knowledge and Conax Buffalo engineered designs make high pressure wire and probe sealing possible up to 30,000 psi. Assembly material selection is critical to sealing performance, and Conax Buffalo engineers have the experience to meet the exact requirements of your application.
ELECTRODE SEALING
(Top) This standard EG750 sealing gland is designed for installing large power leads into vacuum chambers and autoclaves. The sealing gland is vacuum/pressure rated from 5 x 10 -6 TORR to 1500 psi.

(Middle) Conax Buffalo custom-designed this one inch diameter electrode sealing gland capable of carrying 4KV AC at 480°F in high vacuum.

(Lower) Our standard EG250 electrode sealing gland, shown with "B" Cap is rated for 2,000 VDC, 95 amperes at 68°F with the supplied copper electrode.
MS THREAD TYPE
Our MS Thread Type sealing glands offer an alternate mounting thread form for applications where pipe threads may not be desirable. The Conax Buffalo soft sealant/0-ring designs form a highly reliable barrier to the environment being contained. Sealing gland materials and thread sizes are selected to meet the application criteria.
