Overview
The Jerguson V16757-9 gage glass is a replacement transparent sight glass engineered for Size 9 liquid level gages used across chemical processing, petrochemical, refining, and utility industries. This flat borosilicate component delivers clear, unobstructed visibility of liquid levels in process vessels, enabling operators to monitor system status and make real-time control decisions. The tempered borosilicate construction ensures durability and thermal resistance for demanding industrial environments.
