GH-6023 Closet brass fitting with rubber

A closet brass fitting with rubber is a durable plumbing component designed for secure, leak-proof connections in toilet (closet) installations, particularly where the water supply line meets the toilet tank. Made from brass—a corrosion-resistant copper-zinc alloy—it ensures longevity in moist environments, while integrated rubber gaskets or O-rings provide a flexible, watertight seal. The fitting typically features a threaded brass body for attaching to the toilet’s fill valve or supply line, paired with a compression nut that tightens onto the pipe, compressing the rubber seal to prevent leaks. This combination of brass strength and rubber flexibility accommodates minor misalignments, absorbs vibrations, and withstands water pressure fluctuations, making it ideal for residential and commercial toilet systems. Easy to install without soldering, it resists mineral buildup and degradation, though periodic checks of the rubber seal are recommended to maintain optimal performance. Its robust construction and reliable sealing make it a preferred choice for critical connections in bathroom plumbing.
