The base fitting surface is smooth and has no adequate gripping surface, but the inside of the barb is socketed with a 9mm hex Allen key pattern. It’s highly recommended to use an Allen Key 9mm (purchased separately) to prevent skin damage to the fingertips while installing the fitting. Please, be advised not to use excessive force when attaching fitting barbs using Allen Key 9mm in order to prevent damage to other liquid cooling products!
These fittings are guaranteed to be compatible with all other EK Water Blocks liquid cooling products.
