• Underwater, wet mateable connections
• Glass-to-metal sealed pressure barriers
• Pressure compensated system

system is designed for long-term reliability

• Modular design to suit varying installation envelopes

in the demanding subsea and downhole

• Standard Ø1/4” (6.35mm) DHG control line interface

environments with sour well (H2S) conditions,
as well as aggressive production and packer
fluids. Interfaces and product performance
have been developed to conform to Petrobras
spec I-ET-3000.00-1516-823-PEK-003, Wet
Electrical Connector for PDG (Permanent
Downhole Gauge).
One of the key technologies that differentiates
Teledyne DGO from others is reliable glassto-metal sealing. The inorganic materials
used provide an inherently stable structure
that exhibits no degradation attributed to

• Dual-barrier philosophy throughout:
- Primary metal seals
- Secondary elastomer seals
- Rig-testable interface seals
• API 6A, 16D & 17D compliant:
- HH material class (sour service)
- Exceeds U temperature class
- Product specification level 2 – PSL 2
• NACE MR0175 compliant
• Simple, quick, secure, reliable Downhole Gauge
