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

LS-74780 All CPVC

LS-1900TFE

LS-1700TFE

Resists build-up of foreign material or sticky media. Float travel remains uninhibited in viscous or corrosive liquids. SPDT switch.

A medium-size solution for ultra-pure liquid level sensing. Made of corrosion resistant PTFE for low particle generation.

Particularly well suited for rough service. Ideal for use in chemical and plating applications.
