Supported Applications
The Omega PFT2 Series consists of vacuum and pressure feedthroughs designed for sealing copper and thermocouple wire applications. These hermetic connectors provide a reliable interface for passing electrical signals through process boundaries while maintaining system integrity.
- Vacuum systems requiring leak rates down to 1 x 10⁻¹¹ cc He/s at 10⁻⁸ torr
- Pressure environments up to 120 psi (8 bar)
- Copper and thermocouple wire transmission in process instrumentation setups
Operating Conditions & Performance
The PFT2 Series operates within a temperature range of -40 to 120°C (-40 to 250°F). The series is rated for pressures up to 120 psi (8 bar) and vacuum limits down to 1 x 10⁻⁸ torr. Performance specifications include leak rates of 1 x 10⁻⁵ cc air/s at 120 psi pressure and 1 x 10⁻⁷ cc air/s at 29 inHg vacuum.
- Out gassing: <0.003% VCM; <0.34% weight loss (sampled at 125°C, cold surface at 25°C)
- Compatible media include oils, solvents, refrigerants, water, and non-corrosive gases
- Avoid strong acids and strong bases
Configuration Options
The series offers two primary mechanical configurations: a ½ NPT plug design (PFT2NPT) and a ½ NPT couple design (PFT2CPL). Both models feature brass construction with PTFE-insulated wire options.
- Wire types: Copper or Thermocouple
- Pairs available: 1, 2, or 4 pairs per unit
- Copper wire specification: 20 AWG stranded with PTFE insulation, 600V rating
- Thermocouple wire specification: 20 AWG solid with PTFE insulation; 48 inL length, -200 to 200°C rating
Housing and Dimensions
- PFT2NPT (Plug): Overall length 27.7 mm (1.09 inch), hex size 22.4 mm (0.88 inch)
- PFT2CPL (Couple): Overall length 48.0 mm (1.89 inch), hex size 22.4 mm (0.88 inch)
Ordering Configuration
Model numbers follow the format PFT2NPT-<WIRE>-<NO. OF PAIRS> or PFT2CPL-<WIRE>-<NO. OF PAIRS>. For thermocouple variants, specify the type (J, K, T, or E) in place of <WIRE>.
Key Product Differences
The primary distinction between models is the mechanical connection style and wire configuration.
- PFT2NPT series: ½ NPT plug design for direct threaded installation
- PFT2CPL series: ½ NPT couple design, providing a longer overall length (48.0 mm vs 27.7 mm) to accommodate coupling requirements
Wire variants are differentiated by material and pair count:
- Copper wire models use the suffix "CU" followed by the number of pairs (e.g., PFT2NPT-1CU, PFT2CPL-4CU)
- Thermocouple models replace "CU" with the thermocouple type letter and pair count (e.g., PFT2NPT-1K for 1 Type K pair; PFT2CPL-2J for 2 Type J pairs)
