Frequently Asked Questions

A “Boro” is the removable tank section that comes with the Billet Box, but why is it called a “Boro”? According to a post by Billet Box Vapor in 2014…

…The BoroTank has a machined borosilicate glass face that slides down so you can just dump your juice in. With so many lovingly crafted rebuildable attys and adapters for the BilletBox we really wanted a clear tank to show them puppies off, there just wasn’t a clear plastic up for the job.

Since the earlier tanks had a Delrin (plastic) face, I guess the name just stuck from there.

Borosilicate glass composites are known for having very low coefficients of thermal expansion, making them more resistant to thermal shock than any other common glass.

Simply put, a Boro mod or device is one that utilizes a “Boro”, whether that be a Billet Box Vapor Boro or one of the aftermarket Boros that are the same size. 

A Boro mod, can also be a device that uses a proprietary tank that utilizes bridges and RBAs that fit the same as they would in a standard Boro.

An example would be the Hellfire MOAB. The tank is different, but still takes standard RBAs and bridges just like a Boro. 

The stock Billet Box Vapor Rev 4 Boros are white with red gaskets. The A-Tank is black with a red gasket.

Other than that, the main difference between the Rev 4 Boro and the A-Tank is the opening at the bottom for the positive pin of your coil or RBA. The Rev 4 Boro used to come with the OCC adapter (now SMOK Nord Adapter) and the A-Tank was initially made to work with the Aspire Nautilus coils.

Billet Box Vapor recently released a SMOK RPM coil adapter for use with the A-Tank. There is also a bridge called the BriJG that uses the A-Tank with PNP coils.

The Rev 4b Billet Boxes come with an OCC Coil Adapter. This is what we call a bridge. It allows you to use the Kangertech OCC coils in the Boro. There are literally dozens of bridges available for the Boro tank. These bridges allow you to use many different types of mainstream premade coils. The list of bridges available is way too big to list here.

There are also bridges that are RBAs (Rebuildable Atomizers) and some are capable of providing an RTA or RDA quality vape experience in your Billet Box.

RBA stands for Rebuildable Atomizer.
Examples of RBAs are:

– RDA’s (Rebuildable Dripping Atomizer)

– RTA’s (Rebuildable Tank Atomizer)

In terms of Billet Box, RBA’s are atomizers that are installed inside the Boro tank. Some folks refer to them as RBA’s, bridges, or just atomizers (“atties” for short).

One of the earlier, high-quality RBA’s, called the Exocet, was made by Hellfire (The Attysmith).
In the last few years, there have been some fantastic RBA’s created for the Billet Box.

There are also some RBAs inside of all-in-one devices like the VapeSnail, EVL Alien, and others.

Another type of device for your Billet Box is similar to an RDTA, where the coil is built above the juice reservoir and wicking pulls the juice up to the coil. An example of this type of setup is the Boxxer V2.
