Ldi Industries G613-08-A-1 Liquid Level Sight Gauge

Product Description

The LDI INDUSTRIES G613-08-A-1 is a rigid plastic closed circuit liquid level sight gauge designed for monitoring fluid levels in pressurized systems. It features a 1/2-20 UNF thread connection, a sight length of 6-9/32 inches, and an overall length of 8 inches to the center of the base. The gauge is rated for a maximum working pressure of 125 psi and a maximum temperature of 225 degrees F. The housing is constructed of aluminum with a Buna-N seal. This gauge is typically installed by HVAC technicians, plumbers, or industrial maintenance professionals in closed-loop fluid systems.

This sight gauge is suited for residential and light commercial closed circuit systems where visual liquid level monitoring is required. It installs directly into threaded ports on tanks, reservoirs, or piping assemblies. The 1/2-20 UNF thread pattern and compact sight length make it appropriate for installations with limited panel or enclosure space. The Buna-N seal material provides compatibility with a range of common hydraulic and cooling fluids used in closed circuit applications.

Key Features

• Closed circuit design for pressurized liquid level monitoring
• 1/2-20 UNF thread for direct port installation
• 6-9/32 inch sight length for clear fluid visibility
• 125 psi maximum working pressure rating
• 225 degrees F maximum temperature rating with Buna-N seal
• Aluminum housing for durability in industrial and mechanical environments

Compatibility

Designed as an OEM-style replacement or direct-fit sight gauge for closed circuit liquid level monitoring applications requiring a 1/2-20 UNF threaded connection and a rigid plastic sight window.

Installation Notes

Installation should be performed by a qualified technician. Depressurize and drain the system before removing or installing the sight gauge to prevent fluid discharge or injury. Use appropriate thread sealant rated for the fluid type and operating pressure. Inspect the Buna-N seal for proper seating before returning the system to service.
