Q I am looking to build a vacuum attachment so I can vacuum through a 10-mesh screen with a plant v...... Read moreA Unfortunately, we do not offer vacuum fittings. The folks at Ideal Vacuum may be able to lend a hand.
Do you offer the 2" screens in a smaller mesh size?
Thanks , Frank

Q Do you offer the 2" screens in a smaller mesh size? Thanks , FrankA Hi, Frank. We just added two more mesh screen gaskets for 2" and other sizes for BUNA material. The mesh sizes added were 60# and 100#. Please let me know if you need any other varieties and I can send you a quote.
