Conbraco E1818-00 Brass Washer

The Conbraco E1818-00 Brass Washer is a precision-engineered 3/4-inch friction ring specifically designed for liquid level gauges and A/C compressor assemblies. As a veteran-grade HVACR replacement part, this washer provides the critical uniform thickness required to maintain consistent pressure distribution between the glass gasket and glass nut. Fabricated from high-purity corrosion-resistant brass, it is built to withstand extreme thermal cycling and high-pressure environments typical of industrial boiler systems and commercial refrigeration units. Its 3/4" nominal size ensures a standardized fit for Apollo Valves water gauges, effectively preventing refrigerant and lubricant leaks while aiding in heat dissipation. For contractors managing drain system maintenance or gauge glass repairs, this OEM-spec hardware ensures a pressure-tight seal that protects the integrity of the entire assembly and reduces the risk of costly system downtime.

• Superior Material Integrity: High-quality brass construction offers excellent chemical stability and resistance to wear, even when exposed to harsh refrigerants and lubricants.
• Precision Sealing: Functions as a high-performance friction ring to ensure the glass gasket remains securely seated within the water gauge nut.
• Thermal Conductivity: Naturally conducts heat away from critical sealing points, extending the service life of adjacent soft gaskets.
• Universal Compatibility: Standardized 3/4-inch diameter makes it a versatile stock item for various Conbraco and Apollo HVAC fittings and compressor models.

• Where is this washer typically installed in a water gauge? It is placed between the glass gasket and the glass nut to prevent the nut from twisting or damaging the gasket during tightening.
• Can this be used in potable water systems? While brass is highly durable, you must verify the lead-free requirements for your specific plumbing code before installation in potable lines.
• How does this assist with A/C compressor maintenance? It maintains a rigid, leak-proof connection at key ports, preventing the loss of refrigerant and maintaining optimal system head pressure.
