Deluxe White Drain Valves for Custom Loops

This two-pack of Bitspower BPTA-EFW-V2-DW fittings provides a dedicated drain point for liquid-cooling circuits. Each valve uses a 1/4-inch thread and an integrated mechanism that opens when the included male fitting is tightened. The brass construction and hidden O-ring design aim to prevent leaks during coolant removal. They are intended for builders assembling or maintaining a custom water-cooling loop.

Suited for Maintenance-Focused Builds

These valves suit enthusiasts who want a simple way to empty coolant without disconnecting tubing or components. The push-to-open action works with standard soft-tube and fitting kits such as the BPM-DTB series. Builders who prefer hard-tube-only assemblies or who have no low point in their loop for a drain port will not benefit from this design. The pack contains two valves, so single-port needs may leave one unused.

1/4-Inch Thread with Integrated Valve

The defining specification is the G1/4 threaded body combined with the internal valve that activates only when the supplied male fitting is screwed in. This mechanism allows coolant to flow out on demand while sealing automatically when the fitting is removed. Compatibility depends on the loop having a G1/4 port at its lowest point; other thread sizes or port locations will not work with these fittings.

Questions about this item

How does the 1/4" thread drain valve work once installed at the lowest point of the loop?

The integrated valve stays closed until you replace the cap with the included male fitting; tightening that fitting presses the valve open and lets the coolant flow out cleanly.

What does the 1/4" G-thread interface cap in practice?

It mates with any standard 1/4" BSPP fitting or soft-tube adapter, so the connection is limited only by the thread standard itself.

What clearance does the brass body need to fit and mount properly?

The compact brass housing with hidden O-ring seats directly into a 1/4" port, requiring only enough room to screw it in and attach the male fitting.
