Bottle gully 110mm back boss connection

[jonohanson]

Hi, looking to connect to one of the closed bosses on a osma 4D900, there are 3 closed bosses. What do I need to connect a 110mm? It's this one https://www.travisperkins.co.uk/110...gully-87-5-110mm-closed-bosses-4d900/p/711865 thanks

From memory, I'm pretty sure the Bosses are a 110mm socket, so a 110mm spigot will fit, use solvent weld to make the joint.
