TTMA Sight Glass, Acrylic, 3"

Sight glasses offer operators reliable viewing of product flow through critical points of a plumbing system. The tank truck (TTMA) sight flow indicators below feature an all-acrylic construction designed for unimpeded viewing clarity and added durability. Acrylic sight glasses fit between standard TTMA flanges in sizes as noted. Compared to other sight flow indicators that feature built-on metal housings, acrylic sight glasses are an economical yet durable option for operator viewing anywhere along the plumbing system. Cork Buna, Viton®, or Teflon gaskets are available to ensure a leak-proof seal between tank truck flange fittings (call to confirm chemical compatibility).

NOTE: VVTTFSG6 has 8 bolt holes. For a 12-hole version please order VVTTFSG6-12.
