Four matte black G1/4 inch stop fittings with hidden O-rings

Bitspower

Bitspower G1/4" Matt Black Stop Fitting 4-pack

SKU CH-2CP3-PSBXX

Four G1/4" matt black stop fittings with hidden O-ring design for sealing water-cooling loops

  • G1/4" thread fits standard water-cooling loops
  • Matt black E-plated brass matches dark builds
  • Hidden O-ring design prevents visible seal gaps
  • Four fittings per pack covers multiple ports
  • RoHS compliant brass meets restricted-substance rules

Four G1/4″ stop fittings for custom loops

This set contains four matt-black brass stop fittings with G1/4″ threads. They seal unused ports in a custom water-cooling loop and hide the O-ring inside the body for a clean look. Each fitting is five millimetres long and RoHS compliant.

Check thread compatibility and port count

Verify that every component you plan to close uses a standard G1/4″ female thread. Count the open ports on your radiators, blocks, reservoirs and distribution plates so you know how many of the four fittings you will actually install.

Thread directly into G1/4″ ports, no adapters needed

The fittings screw straight into any G1/4″ opening, requiring no extra couplers or tools beyond a hex key. They plug gaps left by future expansion plans or unused drain ports, keeping coolant contained while maintaining a uniform black finish across the loop.

Questions about this item

What does the 4-pack include and is anything else required for installation?

The pack contains four G1/4" matt black stop fittings made from brass with an E-plated finish. Each fitting has a 5 mm thread length and a hidden O-ring. No extra parts are needed if your water-cooling components already have matching G1/4" ports.

Why choose the 4-pack instead of buying single fittings?

The 4-pack supplies exactly four stop fittings — enough to seal unused ports on a typical CPU block, GPU block, radiator and reservoir — and costs less per piece than purchasing them individually.

What does the 5 mm thread length mean when the fitting is screwed into a G1/4" port?

A 5 mm thread engages the full depth of a standard G1/4" female port, allowing the hidden O-ring to seat fully and create a leak-tight seal without bottoming out or protruding.
