Replacement Connector for Tank Series Inline Filter
Two of these connectors are required to link a tank series inline filter (IRR-C120-FILTER) to the 13mm tank series back bone tube. They are a very specific fixing for this one singular purpose.
Each tank series will come with an inline filter and two 13mm tube connectors in the box, so if you are considering a tank series purchase you won't need to buy these initially. However, should you need a replacement inline filter 13mm tube connector in the future, this is what you need. As the fail rate on these parts is very low they are sold as singles as it's unlikely two would fail at the same time.
