Usage
Specs



  • All mounting surfaces require a 32 finish
  • Do not over tighten bulkhead connectors when mounting.
  • Care must be taken not to damage contacts in unmated connectors
  • Contact surfaces must be dry prior to mating.
  • Lubricate O-rings with Dow Corning #111 Valve Lubricant or equivalent.
  • Keep O-ring grooves clean and avoid cuts and nicks in the O-ring. Replace O-rings when re-mounting connectors.
  • Avoid contact with solvents.
  • Avoid sharp bends at cable entry to connector.
  • Elastomers can be seriously degraded if exposed to direct sunlight or high ozone levels for extended periods of time.
