TracTuff Notched Dual ORB Bung

Description

The TracTuff Dual ORB Bung is the coolest dual inlet/ outlet bung you never knew you needed. The concept came about shortly after my idea to produce a single ORB version that essentially took the place of my traditional extruded tube swirl pot inlet/ outlet connections.

The dual ORB design makes the application of this product pretty specific; I’m thinking remote mount swirl pots for V engines (V6, V8, V10, or V12) or flat 4 or 6 engines that typically have two water outlets (one on each cylinder head) that you want to merge at the swirl pot and exit as a single line.

What I love most about this product is the space it saves! I’ve made several dual inlet swirl pots over the years, and every time I make one where both inlets point the same direction (shown below), it’s a real bitch to keep both inlets close together and weld in between the two. These work on both 3.00″ and 4.00″ diameter cylinders but you must cut the cylinder so as to countersink the bung.

NOTE: You can purchase this product as an “upgrade” on any dual-entry swirl pot if the option isn’t already listed on that swirl pot, as well as a stand-alone part if you’d like to weld it yourself. DIY products do not qualify for “upgrade” pricing. If you will be welding this… I’d like to share my experience welding what’s shown above. I don’t know if I put too much heat into it initially (started with the thicker part), but after it was done, I lubricated the threads well and screwed in a port fitting, and it didn’t go in but half a turn. I unscrewed the port fitting, inspected both threads (all looked good), so I added more lube to both parts and reattempted. I was able to work the fitting in slowly… but it ultimately it wouldn’t go in any further and I didn’t want to ruin the part. So I removed the fitting and chased the threads with my 1-5/16″-12 tap and all was good!

Threads are checked prior to welding and all was smooth as butter! So I strongly recommend having a tap on deck. I do not offer any kind of warranty on DIY parts and you agree to accept all risk and responsibility by purchasing this product.
