1.5" Tri Clamp (Teflon) PTFE Screen Gasket 316 (20Uf Micron) Screen Stainless Steel Pharmaceutical Grade Filter Mesh. PTFE Inverted Envelope With Floating Stainless Mesh! With FDA Certification (1.5")

Keep in mind this is a very very fine mesh filter so you need to ensure your particle load is very low so you don't plug it. Also it will add a fair amount of restriction so don't use this unless you really need fine filtration of any errant particles. Item merely comes in a thin plastic ziplock so there is potential for damage especially if you order with a bunch of other parts.Overall, I am happy with this filter and it helps round out my collection of filters for various processes.
