Most Nalgene® closures and those of other manufacturers can be retrofitted with these connectors for liquid transfer without a ventilation and venting device. To do this, simply drill two fitting holes in the closure, feed in the insert and tube connectors and attach tubes with 6 or 13 mm internal diameter. Nalgene® closures 53B (53 mm) can only be fitted with the 6 mm tube connectors, the 83B (83 mm) closures can be equipped with both 6 and 13 mm connectors.
