Sealing Glands Introduction

Pressure and Vacuum Sealing Assemblies

Conax Technologies designs and manufactures a complete line of pressure/vacuum mechanical sealing glands and assemblies for wires and probes for virtually every industry. A wide range of catalog standard sealing glands are available from stock, while unlimited custom designs are also available for unique wire or probe sealing applications.

Exclusive “Soft Sealant” Technology

Conax Technologies’ exclusive “soft sealant” technology enables easy assembly of the sealing gland by simply inserting the wire or probe and torquing the gland cap. Replaceable sealants permit repeated use of the stainless steel fitting for easy installation and service in the field. Our standard sealant materials include Lava, Teflon®, Neoprene, Viton® and Grafoil® and are designed, depending on gland type, to seal pressures ranging from vacuum up to 10,000 psi/690 bar involving temperatures ranging from -400°F to 3000°F/
-240°C to +1650°C. Other sealant materials are available for custom applications.

Wire and Probe Sealing

In wire sealing, we routinely accommodate in one gland from 1 to 16 conductors ranging from 24 AWG to 3/4″/.03mm diameter to handle a voltage range from the millivolt level up to 8000 volts and currents up to 400 amps. In probe sealing, from 1 to 40 probes, ranging in size from 0.020″/0.5mm to 1.250″/32 mm diameter, are routinely pressure or vacuum sealed in a single unit. Beyond these, we offer custom or special assemblies.


Conax Technologies Model PG Packing Glands provide pressure/vacuum sealing for tubes, proccess pipes, cable or any single element assembly (not electrically isolating), including thermocouples, RTDs, thermometers, thermistor probes, capillary tubes, tubewells, multi-pair cables and analyzer sample tubes. PG glands seal against gases and liquids and resist element movement under pressure.

Process Analyzer Sample Probe Assembly (SPA) with Conax Technologies Packing Gland (PG)


The Conax Buffalo Sample Probe Assembly (SPA) is used to hot-tap a sample probe into a process through a process isolation valve as depicted below. Optional materials for the Sample Probe and the Conax Buffalo Packing Gland body (wetted components) are available. Refer to the Conax Pressure and Vacuum Sealing Assemblies Catalog #5001B or our website for available options such as following
316L SST

Monel 405

Hastelloy C276

Inconel 600

Refer to the Conax Pressure and Vacuum Sealing Assemblies Catalog #5001B for temperature and pressure ratings for static conditions. Pressure ratings are reduced when the sealing gland cap is loosened to allow for the insertion or extraction of the Sample Probe.
