The 90 degree double-ended sewage coupler is manufactured according to the following standards:
INSO 9119-1 and EN 1329-1
This product is for when there is a need to change the pipe size in the building’s sewage system. In these cases, the conversion fitting group is used. This connection operates between two different sizes at a 90-degree angle and allows the pipes to be connected to each other when changing the pipe size without causing any fluid or waste leakage into the sewage discharge system.
This product has two female ends (two coupling ends) and one male end.
The 9119 sewage fittings of Oraman Company will be delivered to our valued consumers in white and in a carton.
