The microduct inner diameter does not affect to the functioning of the gas blocks.

Before the optical fibre cable installation, the compression nut must be completely unscrewed to open position. In that position the system is not sealed, and the cable can pass through the gas block freely.

After the cable installation, in order to seal the system, the compression nut must be screwed firmly to closed position. Do not pull the cable when the gas block is in the closed position to prevent possible damage to the gas seal.

If the gas block is used with lubricants, the customer or end user is responsible to check the lubricant chemical compatibility with the construction materials of the gas block.
