3/8" (.375 inch | 9.5 mm) Premium Curved 304 Stainless Steel Concave Pipe Screens (10 Pack)

Will take a long time to burn out, very sturdy, not flimsy like screen wire. I use a paper clip to clean out the holes in between regular cleaning. Soak them in alcohol and they are good as new.

Just as the title says. I bought this to replace the chamber screen in my Boundless CFX dry herb vape. It fits perfectly. The 13mm size might provide a slightly tighter fit, the12mm does come out easily when you empty the vape, but that's fine with me. It completely covers the bottom of the chamber and does not rattle around or anything.The product feels quality made, I like the design and quality better than the screen that came with the Boundleess CFX. Shipping was extremely fast, got it in 1 day.

Fast shipping.The 10-pack of 5/8” stainless steel screens actually arrived with ten (10) screens. Nice. I knew I had to review these screens!The screens have very good air flow. Light and airy, yet firm and demanding!My estimated count for the number of “flow holes” on one screen is approx. 35 holes. Two thumbs up.FYI: the 5/8” screen size fits the Invincibowl metal bowl perfectly, like a soft and supple terp glove. The 5/8” screens drop right into the Invincibowl. No modifications, no filing, drilling, flame throwers or Bowie knives necessary to make it fit.Depending on the shape of the bottom of the bowl of your choice — whether the bottom of your bowl is flat, concave, jagged, etc. — this screen is functionally tops.For example, one can hold the screen sitting flat in the palm of your hand, and flip the screen over for concave vs. convex use. Pretty cool.Pro Tip: for other glass bowls that have a flat ground bottom inside the bowl (surrounding the bowl’s blow hole), the slightly concave screen shape can also simply be flipped over to serve like a slightly mini “mound” to functionally keep air sweetly flowing underneath the screen and not leave any spot un-blazed. A worthy, wildly popular even burn either way.Easy to clean: rubbing alcohol and salt is easy.

great, easy enough to clean, but they are tiny and easy to lose, got through them in a couple week, won’t be reordering because of price.

Great product.

These are great. I like the design. Sits well in glass bowl. But the small holes restrict airflow too much for me personally. So I used my dremel to hog some of the holes out and it improved, but I think with a little more work it will work out great as long as they don't burn through/turn to carbon after some use

First and foremost, I would like to thank ALL of the reviewers who heavily influenced my decision in purchasing these. I got 4 sizes; 1/4, 3/8, 1/2 and 3/4. As stated in other reviews, these are very easy to lose, especially the 1/4! I will no longer use wire screens. Since most tobacco people know their pipe sizes, I am now going to address my 420 reviewers to hopefully save them some sizing issues, and explain just how these little babies work. NOTE: This is not an admission or suggestion, rather, economical and financial friendly information ONLY and I am addressing those of legal age and status. ;).1/4: If you use a glass hand pipe or typical cone/ bowl shaped slide, this will work best in most cases. It is concaved, and will sit perfect over that little hole (most handpipes/ hand held bubblers, and the typical 14mm and some 19mm bowls/ slides, cone and bowl shaped only. It should fit like a plug in a sink giving you 100% of the real estate in your bowl; simple drop in and upside down tap to get out. Example: Grab Labs Funnel Bowl 14mm. This size should cover the majority of people. Easiest to lose and most difficult to find after losing.3/8: All 14/19mm cone/ bowl shaped slides, custom and after market pieces; or if the 1/4 is just a tad bit too small. Should fit like a drain plug. Example: Ehle Large Funnel bowl 14mm only. Custom aftermarket pieces with slightly larger openings in the bottom of the bowl.1/2: Custom aftermarket 14/19mm slides with an larger than average hole in the slide, cup spapes only. Examples: Grav Labs 14mm Octobowl, Ehle Large Cylinder 14/19mm and Ehle Large Funnel Bowl 19mm only. Typically everything at this size is custom aftermarket slides and pieces.3/4:. The only slide that I know that requires this is a 19mm cup (Chinese version with glass screen bottom) like the Grav Labs Octobowl.Cleaning: Use the same solution you use to clean up your glassware such as Orange Chronic or something like that I imagine.In closing, I'm totally happy all the way around with the vendor, Amazon and the product (s) itself. I would recommend to anyone using a smoking apparatus of some type, especially those into scientific glass for health reasons. And I feel that 1/4 is best, unless of course, you're one of those that collect scientific and heady glass pieces as a hobby. I don't know, I'm just saying. Hope I was able to help with sizing. Enjoy whatever it is you do!

These were Not 1/4 " they were too big...1/4 inch on the left...

Exactly what I've looking for so long, no more twisting, brushing, cleaning those thin screens. Perfect size, nice construction, easy to clean, cleaner and smoother smoke. Also the 10 pack will last you years if you take care of them and don't lose them as they are nice and thick stainless. I find this size to be the most standar for all pipes, allowes you a proper load of green.

yo creaba los mios propoios con una lata tijeras y lo perforaba con clavo ero la lata no es del mismo material que esto el aluminio se destruia con el uso y estas cosas son de acero puroeste producto esta hehco de un metal especial para fumar asi qeu es una gran compra, me costaron en si 30 pesos mexicanos cada uno, un pack de 10 fueron 300 y lo vale totalmente, tengo una smoke shop cerca pero no tienen nada de esto

Never got it, I was informed it got lost while being shipped. :-(. It looks good in the pics though.

Honestly got the wrong size, but I can already tell than I'm gonna love the re-order!

I've used every kind of bowl/pipe screen there is. These are the best. Perfect fit and durable, and the holes are just the right size for ground herb. The only downside is you'll lose screens in the ashtray if you just bang your pipe out, and then you have to dig for it. I also bought the 1/2" for use in a larger pipe and bong bowl. IAlso worth noting I received 12 in both my orders of 10 packs. :)
