Rubber gasket and lock ring once used can not be re-used.Storage should be in indoor. If stored outdoors unavoidably, rain drop, dust and direct sunlight should be avoided.So do not freeze, keep it warm.

I think that it is kind if there is the enclosure of the construction procedure manual, such as the method of driving the lock ring and the installation position of the rubber packing. LA couplings that can be connected without cutting screws also use amateurs in waterworks like me. It does not necessarily confirm the electronic catalog.
