Description

Example: PG5-500-A-V

Conax Technologies has a history of creative innovation that results in unique product solutions and design improvement. With the HPG High-Performance PG Series, Conax has found a way to improve one of our time-tested solutions. The result is an exclusive, high performance compression seal fitting that is only available from Conax.

Employing PEEK® as a sealant material offers unique properties, such as chemical resistance rivaling PTFE, higher operating temperatures, a lower expansion rate, and little to no cold flow—with almost no trade-offs.

By optimizing the fitting design and using a PEEK® sealant,
we have been able to increase pressure performance by
more than 1700%.

If you need to seal on a single sensor, electrode, tube or conductor, Conax Technologies has a variety of options for you. For high-performance electrode feedthroughs (8,000V max, 200A max), please request Conax brochure 6068.

The HPG High-Performance PG Series compression seal fitting is especially well suited to the unique conditions found in furnaces, autoclaves, environmental chambers, oil and gas applications, and chemical and biochemical reactors, where process temperatures and pressures combine to create challenging environments.

In addition to the bore sizes listed in the chart on page 2, Conax can also provide fittings with metric or custom bore sizes.

These fittings are available with options similar to those
available on our standard compression seal fittings including:

Process connection options:

  • NPT (standard)
  • Weld neck
  • Parallel thread (MS/SAE/BSPP)
  • ANSI or DN flanges

Body material options:

  • 303SS (standard)
  • 316LSS
  • Inconel 600
  • Hastelloy C276
  • Monel 405
  • NACE
  • Other materials upon request

Bore Sizes

Replacement parts are available to keep on hand,
minimizing down time and providing instant repairs
if damage should occur.

The HPG Series bodies have special internal configuration for use with Conax PEEK® sealants. Use of other parts or materials will result in lower to significantly lower pressure ratings.

Conax Technologies Model PG (Packing Gland) fittings provide pressure/vacuum sealing for tubes, process 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 fittings seal against gases and liquids and resist element movement under pressure.
