Four silver G1/4 inch brass stop-fitting valves with hidden O-rings

Bitspower

Bitspower G1/4" Silver Shining Stop Fitting Valve 4PCS

SKU CH-88SH-8K11Q

Set of four G1/4" stop-fitting valves in silver-finished brass for custom water-cooling loops

  • Controls flow in custom loops with a built-in valve mechanism
  • G1/4" thread fits standard water-cooling components directly
  • Brass body with nickel plating resists corrosion over time
  • Hidden O-ring design prevents leaks at connection points
  • Four-piece pack covers multiple ports in a single purchase

Custom-loop valve kit

This four-piece set of G1/4" stop fittings lets builders isolate individual loops or components for maintenance without draining the entire system. The valves are machined from brass with a nickel finish and are aimed at enthusiasts assembling high-end liquid-cooling circuits.

G1/4" thread compatibility

Each valve uses a standard G1/4" thread with a 5 mm engagement length, matching the vast majority of water-blocks, radiators, reservoirs and fittings sold for PC cooling. The concealed O-ring design seals against the mating surface rather than the thread itself.

Zero active thermals

The fittings contain no moving parts, fans or electronics, so they add no noise, vibration or power draw to the loop. Thermal contribution is limited to the small brass mass reaching coolant temperature, which is negligible in normal operation.

Questions about this item

How does the 5 mm thread length affect sealing inside a custom loop?

The 5 mm G1/4" thread engages standard water-block ports fully while leaving enough clearance for the hidden O-ring to compress and seal without bottoming out.

What does the G1/4" thread standard limit in a build?

G1/4" is the near-universal PC water-cooling thread, so these valves fit almost every block, radiator, reservoir and pump top, but they cannot mate with NPT, metric or proprietary fittings.

How much wrench space do the four valves need to install side by side?

Each valve has a low-profile hexagonal body designed for a standard G1/4" fitting spanner, allowing tight side-by-side mounting in crowded distribution plates or multi-port tops.
