Manufacturer: MEIKO ENGINEERING
Model: RD

The RD coupling is a rubber attachment that connects the large and small reservoir with a piping system.

Function

Low drainage and piping system to avoid leakage and flooding
RD couplings are fitted into the gap between the tank and the pipe.

Durability of RD couplings

Although the RD couplings are made entirely of natural rubber, the joints still have the following limitations:
Rubber degradation due to prolonged sun exposure
Oxidized by heat and steam from generators
Gases such as SOx, NOx, HCl, etc. also cause rubber to get corroded
