Ldi Industries G613-10-A-1 Liquid Level Sight Gauge

Product Description

The LDI INDUSTRIES G613-10-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 8-9/32 inches, and a maximum working pressure of 125 psi. The housing is aluminum construction. A Buna-N seal provides fluid-compatible seating. The gauge is rated for a maximum temperature of 225 degrees F with a 70 degrees F standard working temperature. Licensed plumbers, HVAC technicians, and industrial maintenance personnel install this type of gauge during system commissioning or scheduled service.

This sight gauge is suited for closed circuit liquid level monitoring in hydraulic, lubrication, coolant, and similar pressurized fluid systems. It mounts with the 1/2-20 UNF thread connection and provides a 10 inch overall length measured to the center of the base. Its rigid plastic sight window allows direct visual confirmation of fluid level without opening the circuit. Typical applications include industrial machinery, fluid reservoirs, and mechanical system panels where continuous visual monitoring is required.

Key Features

• Closed circuit design maintains system integrity during fluid level inspection
• 1/2-20 UNF thread for secure, standard connection
• 8-9/32 inch sight length for clear fluid level visibility
• Rated to 125 psi maximum working pressure
• Buna-N seal for compatibility with common hydraulic and coolant fluids
• Aluminum housing for durability in demanding service environments

Compatibility

Designed as an OEM-style replacement or direct-install sight gauge for closed circuit fluid systems using 1/2-20 UNF threaded ports operating within 125 psi and 225 degrees F temperature limits.

Installation Notes

Installation should be performed by a qualified technician familiar with pressurized fluid systems. Depressurize and drain the system fully before removing or installing the sight gauge. Apply appropriate thread sealant compatible with the system fluid and verify torque against the equipment manufacturer's specifications. Confirm fluid and pressure ratings are within the gauge's published limits before returning the system to service.
