Ldi Industries G607-06-A-1-2 Liquid Level Sight Gauge

Product Description

The LDI INDUSTRIES G607-06-A-1-2 is a closed circuit liquid level sight gauge with a pipe adapter, designed for monitoring fluid levels in pressurized systems. It features a 4.5-inch sight length, a maximum operating pressure of 290 psi, and a 0.25-18 NPTF threaded connection. The aluminum housing keeps weight low while providing corrosion resistance in typical fluid service environments. Buna-N seals are included, making it suitable for petroleum-based fluids and general industrial lubricants. This gauge is installed by HVAC technicians, plumbers, and industrial maintenance trades in closed-loop fluid systems where visual level confirmation is required.

This sight gauge is suited for closed circuit liquid monitoring in residential and commercial mechanical systems, including hydraulic lines, oil reservoirs, and fluid handling equipment. The pipe adapter fitting allows direct installation into standard NPTF-threaded ports. The 4.5-inch sight window gives a clear view of fluid level, and the 290 psi pressure rating covers most building mechanical and light industrial service pressures. Total installed length to center of base is 6 inches, with a 7.625-inch overall length.

Key Features

• 290 psi maximum pressure rating for pressurized closed circuit fluid systems
• 4.5-inch sight length for clear visual fluid level confirmation
• 0.25-18 NPTF threaded connection with included pipe adapter
• Aluminum housing for lightweight, corrosion-resistant construction
• Buna-N seal compatible with petroleum-based and general industrial fluids
• 7.625-inch overall length with 6-inch length to center of base for straightforward dimensional planning

Compatibility

Designed as an OEM-style replacement or new-installation sight gauge for closed circuit liquid level monitoring applications using standard 0.25-18 NPTF threaded ports rated up to 290 psi.

Installation Notes

Installation is typically performed by a licensed plumber or qualified mechanical technician. Depressurize and drain the system before removing or installing any sight gauge fitting. Apply thread sealant appropriate for the fluid type to the NPTF threads and tighten to snug fit without over-torquing the aluminum housing. After installation, slowly re-pressurize the system and inspect all connections for leaks before returning to service.
