POSEIDON Invincipole Infinity- Blue 18mm/14mm Downstem

(18 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


This gorgeous blue metal downstem is uniquely designed to elevate your smoking experience. It is armored using aerospace-grade aluminum and finished with a hard-anodized coating. It’s also adjustable in length which means you’ll never have to play the guessing game again. Simply glide to the size of your bong with ease. The versatile design allows you to adapt your slide from small bongs to larger pieces by ranging from 3 inches to just under 6 inches. You’re able to adjust in small increments for the perfect insert! These accessories are designed to fit the needs of cannabis enthusiasts and novice smokers alike!

Product Quality

The Poseidon Invincipole isn’t just durable, beautiful, and adjustable. We’ve applied the same screen system as the Invincibowl inside the cap of the Invincipole. That means double the filtration! The pole houses a screen in the multi-hole diffuser which prevents ash and product from seeping through into your bong water. The proprietary high-flow mesh is large enough to provide a smoother hit yet fine enough to withhold gunk from getting through. 

Whether you’re on the market for a new bong bowl and downstem or simply want to upgrade your existing pair for the best smoke sessions- look no further! Grab the perfect smoking accessories packed with features you’ll adore! Backed by a lifetime guarantee, we are certain you’re going to love your setup!

    I really like these. My wife and I both ordered and use them with no problem.

  2. Star

    I honestly doubt it too much before I bought them but I'm so happy I did that I'm getting another set, wish they have in white. They are very high quality, truly one of the best slides I have found in the market nowadays. Recommend to anybody. They adjust very easy and don't get stuck.

    No complaints, great slide, HIGHly recommend.

  9. Luis G. (verified owner)

    Substantial so you feel the weight of it. The screens are great but I do not see myself reordering. I do see myself getting another downstem though because this has exceeded my expectations on every single level.

  10. Izabella Garcia

    This is my first time using Invincibowl products and honestly the only annoying part of this product isn't cheaper. Besides that I would say the convenience of the product and the price are worth the purchase especially if you damage products easily. I would purchase again for sure.

  11. Dj

    Came quickly and in perfect condition ????


    I have a medical marijuana card for my medical issues and this has been a life saver!!!!!!!!

  13. Nelson (verified owner)

    So easy to use and so fast. I really suck at cleaning out my bong so this product is awesome for me. There is no flavor added which I was concerned with initially but it's been great.

  14. Happy girls ???? (verified owner)

    This color is sooo gorgeous! ???? I bought the bowl and the downstem and I am so happy with both ????????

  15. Emerson (verified owner)

    Fast shipping and great product! I really thought I was spending money on something useless, but after reading the reviews I decided to give it a try anyway... I was so jovial to find out it works the way it claims to. I love this thing! I need a few more!

  16. Charles The Machinist

    The construction is of aluminum and stainless steel alloy which is anodized with a hard finish. Machine work is clean including the threads and surfaces; no barbed surfaces or jagged edges at all. The Invincipole has a sturdy perc chamber. Measurements in the product description are accurate. Comes with a extra screens and new screens are reasonably priced for how long they last.

    Bonus: Arrived within 3 days.

  17. Ben (verified owner)

    Works really well with my Poseidon bong bowl. As easy to use as it was on day 1, after weeks of use! I think this is absolutely a 420 necessity. Highly recommended.

  18. Paige B. (verified owner)

    I cannot believe the amount of weed I save with this thing!! NOTHING comes out the other end. Well made, sturdy, removable cap and spare screens included!

    Worth every penny!
