The 87.5 degree elbow tee, sewage coupling tee, is manufactured according to the following standards:
INSO 9119-1 and EN 1329-1
This product is used to change the flow path of fluid and waste, and also, depending on the design of the building’s mechanical installation system, it will be used to change the appropriate angle of the sewage system and also to create branches.Due to the difference of 2.5 degrees compared to the 90 degree angle, it will accelerate the drainage of sewage. Also, in some cases, this connection is used in the implementation of vertical rises of the building due to the lack of relief and the absence of a 90 degree exit angle. Also, since it is a three-ended coupling, it creates the advantage of using fewer connections.
This product has a three-headed female (three-headed coupling)
