MAMOD SIGHT GLASS ASSEMBLY WITH RIVETS
There are two ways for your Sight Glass Assembly to be attached to your boiler.
Either using screws or using rivets. If your boiler simply has holes for the RIVETS then you have come to the right place.
If your boiler is newer, then you will need the screws - IN WHICH CASE YOU WILL NEED GO TO OUR "SCREWS" TYPE.
Tip: When fixing the shaped rubber gasket into place you DON'T need to use a gasket sealant.
