Fluoropolymer (PTFE) Sight Tubes - Flare-Thru Flanged Sight Flow Indicator

Translucent Chemfluor® FEP fluoropolymer material offers numerous advantages with a see through transparency. These sight-flow indicators are available with flanged (ANSI B16.5, lap joint style) class 150# epoxy coated flanges as standard; optional 316L class 150# flanges are available.

The Flare-Thru flanged unit features a non-entrapment, flared-over design. The tube is manufactured with a heavy gauge Chemfluor® FEP fluoropolymer that will not break in high stress or cold temperature environments. This feature also means there is no need for bulky protective sheaths or supporting bolts...units take up less space and weigh less.

Chemfluor® FEP fluoropolymer is a non-aging, non-yellowing material with a non-stick surface that cleans easily and promotes minimal pressure drop.
