This 304 stainless steel tri-clover bulkhead includes seals and will attache to any standard tank. Just drill a hole and tighten this item to your vessel wall and in moments you will have a tank with tri-clover fittings on it. It perfectly suit for standard 47mm holes from Turbo boiler of T500 or stainless steel lids for 35L/65L Brewzilla, but not suit for Pure distilling boiler as it is too small for that.
You can use to drill a 48mm hole into the wall of a tank or lid of a fermenter then fit this 2inch tri-clover fitting without any welding.
