SPGA with Integral Pin

Our tightest multi-hole split seal fittings—now with catalog pressure ratings

When applications demand multiple elements to pass through a single pressure boundary, the integrity of the seal becomes critical. Traditional multi-hole split compression seal fittings can introduce uncertainty—often requiring factory consultation or application-specific torque development to achieve acceptable performance.

Conax Technologies addressed this challenge with SPGA and DSPGA split seal fittings—our multi-hole split compression seal designs, engineered to deliver higher-than-typical pressure ratings with confidence.

The first of their kind from Conax

SPGA and DSPGA fittings are the first Conax multi-hole split seal fittings to carry both hydraulic and pneumatic catalog pressure ratings.

  • SPGA assemblies seal on multiple elements with a single split
  • DSPGA assemblies seal on multiple elements with a double split

Because these fittings carry published catalog ratings, users can specify them with confidence when operating within those limits—without consulting the factory or developing custom torque values and associated pressure ratings.

Higher sealing pressure for a tighter seal

The SPGA and DSPGA designs transmit a greater amount of pressure from the cap to the load-bearing washer, follower, sealant, and seat set. This increased load path results in higher sealing pressures, creating a tighter seal on both the fitting body and the elements themselves.

The result is improved sealing performance in demanding pressure and vibration environments—without sacrificing serviceability.

Designed for easier assembly and maintenance

Both SPGA and DSPGA fittings feature split seats, split sealants, and split followers, allowing sealants to be replaced without removing the elements from the fitting. This simplifies maintenance and reduces handling of long probes or assemblies. To further streamline installation, SPGA and DSPGA split seals incorporate followers with an integral pin, enabling faster, easier, and safer assembly in the field.

Proven across demanding applications

Conax offers a range of split seal models specifically designed for applications where the diameter of the probe tip is larger than the diameter of the elements at the sealing location. Typical uses include:

  • Analyzer sampling probes with blow-out collars
  • Gas-filled capillary bulb temperature sensors
  • Cable assemblies with factory-installed connectors
  • Long cable or sheath probes requiring easier assembly and disassembly

These fittings are widely used in down-hole oil and gas applications as well as a broad range of general industrial environments.

Sealant options to match your environment

SPGA and DSPGA split seal fittings are available with Viton®, Lava®, or Grafoil® sealants, allowing users to match sealing materials to temperature, pressure, and environmental requirements.
