4-1/2" EIA Connector for 5" Coaxial Cable, Gas stop / Gas pass, O-Ring Sealing

Rev : G | Rev date : 10 Apr 2026

Radio Frequency Systems line of high performance HELIFLEX® coaxial cable connectors are characterized by excellent gas tightness and extremely low losses. HELIFLEX®Lite connectors can be installed with basic hand tools, but the use of dedicated installation tools further facilitates ease of assembly and improves performance.
RFS connectors are fully tested for mechanical and electrical compliance specifications.
HELIFLEX®Lite premium connectors have excellent electrical values and provide outstanding performance for the most demanding applications. The RFS connector design provides maximum sealing integrity and gas tightness.

Features / Benefits

  • Easy installation utilizing only basic hand tools.
  • Tab flare of outer contact attachment means quick and simple installation.
  • No need for sealing compound. The connector is ready for pressurization immediately after installed to the cable.
  • Excellent gas tightness. Overpressure for increased voltage handling is maintained throughout the system.
  • Outstanding VSWR performance improves overall system performance.
  • Totally waterproof, assures safe, long term operation in the harshest of environments.  
  • RoHS (EU) and CRoHS (China) compliant, can be used on a global basis.
