Ill Glass Replacement Downstem Diffuser (All Sizes)

Replacement Diffuser for your Ill Glass Tube or an excellent upgrade for any tube that uses an 18MM downstem! Hybrid design includes both a fine grid pattern that works to create a ton of tiny bubbles during your pull (smaller bubbles = more surface area = improved filtration), as well as a large "escape hole" on the bottom to allow for effortless clearing while letting any snap through material to pass right through. 

See pics for measuring instructions.

Grid color and sandblast may vary from pics.
