Compression Seal Fitting Selection Guide

Single Element Sealing
Use these products when you need to seal a single element such as a temperature probe, tubewell, pipe, etc.These products are capable of sealing on items made of materials such as metal, glass, ceramic or plastic.

  • Packing Gland (PG) Series
      PG
    • For sealing on anything from fragile tubes and soft cables to solid probes or instruments
    • Element diameters range from 0.040" (1.0mm) to 1.50" (47.5mm) pipe

  • Midlock ( MK ) Series
      PG
    • Best used for sealing on metal elements and/or high vibration environments
    • Stainless steel throughout – single ferrule is self-aligning

  • Electrode ( EG ) Series
      PG
    • Fully isolating for electrical power or instrument isolation to 2000V
    • High pressure, high temperature and current capabilities

  • Electrode Teflon ( EGT ) Series
      PG
    • Fully isolating for bare electrical power leads or instrumentation isolation to 8000V
    • Teflon insulation and sealant material for high performance and chemical resistance

  • Split ( PGS ) Series
      PG
    • Seals cables and leads when larger probes or connectors are attached
    • See Split (PGS/SPG/DSPG) Series in Multiple Element Sealing section
      – pages 64-67
Multiple Element Sealing With Factory Installed Leadwires
Use these products when multiple wire feedthroughs are required to carry power or instrumentation signals into pressure or vacuum environments.
These compression seal fittings are manufactured with factory installed leadwires.

  • High Pressure ( HPPL ) Series
      PG
    • For sealing on power leads or instrument leads in high pressure environments
    • For applications with pressures to 30,000 psi (2,070 bar)

      •  


  • High Pressure ( HPEG ) Series
      PG
    • For sealing on electrodes in high pressure environments
    • For applications with pressures to 20,000 psi (1,290 bar)

      •  


  • Power Lead ( PL ) Series
      PG
    • For high performance sealing from 1 to 18 larger gage wires sizes 8 to 20 AWG
    • Rated 600Vac/850VDC @ 55A max – available with or without conductors

  • Transducer Gland Teflon ( TG24T ) Series

Multiple Element Sealing – Without Factory Installed Lead Wires
Use these products when you want to seal multiple elements of the same or different diameters such as metal tubing, ceramic or rigid plastic tube or pipe, temperature probe, a tubewell, low voltage instrumentation wire or a power supply feedthrough. These compression seal fittings are generally manufactured without factory installed leadwires.
