Seal-Connect® XCD

High Pressure/High Temperature


To help service companies meet the need for reliable data and power transmission in extreme temperatures and pressures, Greene Tweed is expanding our line of Seal-Connect® electrical connector technology. Seal-Connect® XCD, our revolutionary, customer-driven technology, enables our customers to reliably transfer data in increasing temperature requirements.

XCD withstands temperatures up to 500°F (260°C) in continuous service at 30,000 psi (2,068 bar). The XCD connector helps users meet exploration challenges inherent in drilling in extreme temperatures, higher pressures, and increased sour gas exposure.

Unlike traditional glass-to-metal sealed designs that involve firing a pin into a metal body with sealing glasses, Greene Tweed’s Seal-Connect® XCD 30,000 psi (2,068 bar) @ 500°F (260°C) connector design features our injection-molded Arlon® 2000 PEEK plastic material. Arlon® materials have been used as insulators in the oilfield industry for more than 20 years. While glass materials are good insulators, high temperatures lead to degradation in the electrical insulation resistance. Because the pins are in such close proximity to the surrounding conductive body, signal loss or degradation is possible. However, Seal-Connect® designs featuring Arlon® PEEK material provide the insulation resistance necessary to protect signals in highly elevated temperatures.


  • A variety of pin materials (e.g., standard beryllium copper, corrosion-resistant Inconel, high-conductivity, oxygen-free copper) enables customers to select the material that will provide the highest conductivity and reliability for their applications
  • Reliable data transfer in pressures up to 30,000 psi (2068 bar) and temperatures as high as 500°F (260°C) allow customers to meet exploration challenges
  • Connector designs use Arlon PEEK material to protect signals from degradation in elevated temperatures
