SIREN Invincipole Infinity- Red 18mm/14mm Downstem

(7 customer reviews)



The new and improved Invincipole Infinity series is an 18mm/14mm joint fitting downstem. It is precision crafted from an aerospace-grade aluminum module with a full-body hard-anodization and a sleek, satin finish. This device is best paired with the Invincibowl but it comfortably admits any 14mm bowl of your choosing. Invincipole features the world’s first Telescoping Technology extending from 3 inches - 5 ¾ inches, fitting a wide range of commonly distributed bongs. The Infinity series features the new pressure lock and release taper joints. The pressure responsive design secures your downstem into the bong then easily releases with a simple click anti-jamming operation, preventing the downstem from wedging in the bong. Meanwhile, internal joints provide superior holding strength plus easy bowl removal with a fluid twist and pull motion. The refined hex head allows you to maneuver the piece with little effort along anti-roll stability while cleaning. Precision lightning ridges make pole extension easy while the inner O-ring seals the directed airflow. The downstem also features a removable multi-hole diffuser cap that houses the final ash defense system, our proprietary stainless-steel screen. This high-flow mesh is reliable, effective, and enhances your smoking experience tenfold.

How to know if our downstems fit your bong



There’s nothing more frustrating than when your downstem breaks and you have to wait to get a replacement. And when you venture out to purchase a new one, you are left wondering if it will fit properly. 

Our products solve these problems and more. This Invincipole is an 18mm/14mm joint fitting metal downstem. It features the world’s first telescoping technology, allowing it to extend from three inches to just under six inches, fitting a wide range of commonly distributed bongs, and takes the guesswork out of replacing your broken slide. The Siren Invincipole is made from an aerospace-grade aluminum module with a full-body hard-anodization and will readily accept any 14mm bowl. 

Add Flare and Style!

Our revolutionary components will add style and flair to your bong and will also perform better than the downstem that came with your original purchase. The precision lightning ridges make pole extension easy with an inner O-ring that seals the directed airflow. It features a multi-hole diffuser that houses the final ash defense system — our proprietary stainless-steel screen. This means less ash in your water and a cleaner bong experience overall. 

Make it easy on yourself and buy an Invicibowl with the same color, or mix and match to switch up your look! You can purchase bundles of both products here. Using the Invincibowl and Invincipole together will guarantee a smooth hit with an even burn. The integrated screens in both units are highly effective while maintaining effective airflow. 

The Invincipole is easy to clean with isopropyl alcohol and salt, easy to assemble and disassemble, and has a lifetime warranty! Our customer service is quick, with an average turnaround of a day. Should you have any issues, contact us here.

    These are a perfect alternative to glass stems. We were a little concerned that they would not function but they out preform anything we have ever used. Highly recommend if you are on the fence.
