Safbung™ Safety Vent Bung

(A) Safety Vents. 
The three patented ports are well above the threads so that the tank will begin venting within a quarter turn.

(B) Durable Threads.
The 2″ NPS threads are machined into a 316 stainless steel casting. Machining includes an operation for removing sharp edges that can gall and interfere with tightening.

(C) Scored Underside.

The scored surface under the lip digs into gaskets, preventing them from spreading and slipping out from between the sealing surfaces during tightening. The benefits is a complete and uniform seal.

(D) Standard Tightening. 
A standard hex lets user users tighten and loosen the bungs with conventional tooling.

(E) Torque Wrench Adapter. 
When consistency is necessary, this adapter lets users tighten the bung with a torque or impact wrench. The adapter fits a standard female 3/4″ socket and a female hex in the center of the bung. Available as an accessory.

(F) Relieve Bottom Thread. 
A chamfer along the bottom makes the threads more durable. Damage to the starting threads, therefore is unlikely should a user drop the bung.

(G) Polished Surface.
An electrochemical process polishes all surfaces, including the threads. The resulting shiny exterior is both smooth and passivated, making it easy to clean and resistant to rust and other forms of chemical attack.

(H) Optional Gasket. 
In stock for immediate shipping.



Once you try a SAFBUNG,™ You’ll want to keep it for the lifetime of your tank-which you can actually do because it’s durable enough to last that long.Unlike a convention bung, this one is made of slightly annealed, cast 316 stainless steel, making it harder and tougher that the throw-away bungs of the past. Moreover, the strategic use of machining and polishing only enhances the material’s durability maintainability.Another reason you’ll never want to replace SAFBUNG™ is that it will become an integral part of your safety program. This engineered bung is both heavy and vented to prevent it from popping like a champagne cork, which could injure workers and damage property. Tests prove that the patented vents begin relieving any dangerous built-up pressure in the tank within a quarter turn.
