Conbraco 9858R-12 Regular Glass

For industrial fluid monitoring, the Conbraco 9858R-12 Regular Glass provides a dependable visual interface for observing media levels in tanks and boilers. This 5/8" OD x 12" gauge glass is engineered for standard pressure applications where clear visibility is paramount for operational safety. As a genuine Apollo Valves replacement part, it ensures dimensional consistency with existing water gauge sets, minimizing the risk of leaks during installation. The tubular gauge glass construction is designed to withstand the thermal stresses found in hydronic heating and low-pressure steam systems. When servicing specialized boiler sight glass assemblies, using the 9858R-12 maintains the integrity of the original equipment specification. For technicians managing high-volume maintenance schedules, these clear glass tubes offer a cost-effective solution for replacing clouded or etched indicators. Prioritize proper gauge glass installation by ensuring compatible gaskets and friction rings are used to secure the 5/8-inch diameter tubing within the valve furniture.

• Precision Dimensions: Features a standardized 5/8" outside diameter and 12-inch length for universal fit in compatible Conbraco/Apollo water gauges.
• Optimal Clarity: Manufactured from high-quality clear glass to ensure unimpeded monitoring of liquid level indicators.
• OEM Compatibility: Direct replacement for Apollo 9858R-12, ensuring matching material properties and pressure tolerances.
• HVACR Performance: Specifically suited for hydronic systems and steam boiler sight assemblies.

• What is the maximum pressure rating for this glass? This regular gauge glass is intended for standard duty; for high-pressure steam over 150 PSI, consider upgrading to high-pressure or Red Line variations.
• Does this include the required gaskets? This part number is for the replacement glass tube only. Gaskets and packing nuts must be sourced separately to ensure a proper seal.
• Can this be cut to a custom length? While glass can be field-cut with specific scoring tools, it is recommended to purchase the exact 12-inch factory-finished length to maintain structural integrity.
