Grav Labs Two Layer Circuit Rig - A Quick Intro

Get double the rotation with the Grav Labs Two Layer Circuit Rig! 

The powerful centrifugal force of this rig’s unique design cools the vapor and makes each hit smoother and tastier.

Also, no need to worry about splashback with this rig; the distinct sharp bend of the neck effectively acts as a barrier between your mouth and the water within the chamber.

This piece includes a 14mm female-jointed domeless nail made of durable, heat resistant quartz, so all you have to do is add cool water to the chamber and get right into the fun stuff!

Top 5 Grav Labs Two Layer Circuit Rig Features 

Double Circuit Percolator

This piece features a Double Circuit Percolator design. This unique perc system causes the water and vapor to spin rapidly to form a powerful centrifugal force. This allows for the best diffusion and filtration. The result is a smoother, cleaner hit with every session. 

Quartz Banger

Quartz is known for its durability and high heat resistance. Aside from that, pure quartz is especially easy to clean, and completely tasteless, allowing you to get the best, most full flavor profile with every session. 

Angled Neck

The Grav Labs Two Layer Circuit Rig was constructed with a bent neck. The bent neck adds a bit of distinction to your piece and also acts as a splashguard, keeping any unwanted water away from your mouth.

Premium Borosilicate Glass

Borosilicate is the ideal material for all of your smoking glass needs. This is because borosilicate is extremely durable and resistant to heat. It is also easy to clean and gives you the best, unadulterated flavor profile.

Flared Mouthpiece

The Grav Labs Two Layer Circuit Rig also has a flared mouthpiece, for the best mouth seal and comfort. Aside from that, the clean, beautiful flare adds a bit of distinction to your rig, which will definitely stand out in any glass collection. 

How To Use Grav Labs Two Layer Circuit Rig

1. How To Operate Grav Labs Two Layer Circuit Rig

To operate the Grav Labs Circuit Rig, start by adding water to the inside of it.

Fill the water all the way up in the bottom chamber. The water should also go a little less than halfway up the stem where your banger sits. Experiment with the water levels until you feel it hit right. 

When you are satisfied with the amount of water in the rig, grab your torch lighter and heat the quartz banger to your desired temperature. 

Once you have it sufficiently heated up, add your favorite concentrate to the banger and gently inhale from the mouthpiece. 

To clear the piece, carefully lift the bowl, inhale, and allow the fresh air to push the remaining smoke out of the rig.

2. How To Get Cool Hits From Grav Labs Two Layer Circuit Rig

To get the coolest hits from your rig, use cool, fresh water with every sesh.

Also make sure you are harnessing the full potential of this rig’s twin turbine percolators by experimenting with different water levels.

Lastly, make sure that you are cleaning your rig with regularity. If you allow too much residue to build up, you will undoubtedly notice a drop in taste and overall quality.

3. How To Clean/Maintain Grav Labs Two Layer Circuit Rig

To clean your rig, empty it out and add some isopropyl alcohol and coarse salt to the inside.

Plug up the holes and then shake the rig for a few minutes to dislodge any stubborn residue. 

To clean the banger, place it into a resealable bag with some alcohol and shake it up.

You can also spot-clean the components using some cotton swabs dipped in alcohol.

Once you are happy with how clean the glass components are, rinse the pieces in hot water.

Finally, make sure to allow the rig and banger to dry off before your next session.
