Weil McLain 383-600-000 Kit

The Weil-McLain 383-600-000 Water Gauge Glass Kit is a critical boiler trim component engineered for precise visual monitoring of hydronic fluid levels. This kit features a 5/8" x 7-3/8" borosilicate glass tube designed to withstand the thermal stresses of high-pressure steam environments, ensuring a clear sightline into the internal water line. Built for compatibility with Weil-McLain EGH, EG, 68, and LGB boiler series (sizes 85-125), it serves as a direct OEM replacement for aged or clouded sight glasses. The assembly includes premium EPDM gaskets and durable brass washers to achieve a leak-proof seal during installation and prevent localized corrosion at the gauge valves. By facilitating accurate water level readings, this steam boiler sight glass helps technicians maintain safe operating conditions and prevent low-water cutoff events. This direct replacement gauge glass is essential for routine boiler maintenance, providing the structural integrity and chemical resistance required for long-term industrial and residential heating applications.

• OEM Precision: Specifically sized at 5/8" OD x 7-3/8" length for a seamless fit in Weil-McLain boiler steam trim.
• Thermal Stability: Heavy-duty glass construction resists clouding and thermal shock in high-temperature steam systems.
• Complete Seal Kit: Includes high-grade rubber gaskets and brass washers to eliminate bypass leaks at the connection points.
• System Safety: Enables immediate visual verification of boiler water levels to protect the heat exchanger from dry fire conditions.

Which boiler models use the 383-600-000 kit?
This kit is engineered for Weil-McLain EG, EGH, 68, and LGB series boilers within the 85 to 125 size range. Always verify your specific boiler series before installation.

What is included in the package?
The kit contains one 7-3/8" glass sight tube, two specialized gaskets for a secure seal, and two brass washers to ensure proper compression and durability.

How do I prevent the glass from cracking during installation?
Ensure the gauge valves are properly aligned and avoid over-tightening the nuts. Use the included brass washers to distribute pressure evenly across the gaskets.
