Large Size – Engineered Plastics

Select from these Engineered Plastics for Aggressive or Ultra-Pure Liquids

Each of these series offers unique features. Choose from this selection

when all-plastic material is desirable and tank space is not restricted.

LS-30 Series–

Polysulfone

For water-based liquids,

with limited use in oils

and chemicals. Cost is

suited for high volume

OEM use. Polysulfone

material of construction

complies with FDA food

contact regulations.
