Thermal Grizzly DeltaMate G1/4" Drain Valve, Black

The Thermal Grizzly DeltaMate Drain Valve (Black) is designed for draining custom liquid-cooling loops. It features a machined brass body and an EPDM rubber seal for durability. The internal, spring-loaded mechanism remains closed during normal operation to prevent leaks. The valve only opens when manually operated, providing a secure way to drain coolant without having to dismantle the loop. This makes it easier to service reservoirs, radiators, and water blocks.

The valve uses a standard G1/4" threaded interface to mount to cooling ports. A built-in 10 mm push-fit connector allows for the direct attachment of 10 mm inner diameter soft tubing. It provides a permanent drainage point that simplifies regular coolant changes, particularly in systems where components are difficult to reach. The matte black finish allows the unit to blend in with most hardware configurations.

• Weight of 52 g minimizes stress on G1/4" ports and acrylic components.
• Compact 12.8 mm depth and 20.6 mm width allow for installation in confined spaces.
• EPDM rubber seal is resistant to chemical breakdown from common cooling fluids.
• Single-pack includes one complete valve unit.
• Low-profile design avoids interference with motherboard components or expansion cards.
