Four black sparkle brass G1/4 inch extenders 15mm long

Bitspower

Bitspower G1/4" Black Sparkle Extender 15mm 4-pack

SKU CH-PBTS-3RJK1

Set of four G1/4″ brass extenders adding 15 mm thread depth with a black sparkle nickel finish and hidden O-ring seals

  • Extends G1/4" threads by 15mm for flexible loop routing
  • True Hi-Flow design maintains unrestricted coolant movement
  • High-quality brass construction ensures long-term durability
  • Black Sparkle nickel finish adds corrosion resistance and visual appeal
  • Hiding O-ring design provides clean, leak-free sealing

G1/4" thread extenders for custom loops

These four Bitspower extenders add 15 mm of reach to any G1/4" port while keeping the inner thread at G1/4". They suit builders who need extra clearance between blocks, radiators or reservoirs without changing the thread standard. The black sparkle nickel finish matches dark-themed builds and the hidden O-ring design keeps the seal out of sight.

Brass construction with high-flow path

Hi-quality brass bodies and a true hi-flow internal bore minimise restriction so coolant moves freely through the added length. The nickel plating is RoHS compliant and resists corrosion during long-term use. Each piece threads 5 mm deep on both ends, giving a secure mechanical joint without protruding into the flow channel.

Stable dimensions under pressure

The rigid brass extender does not compress or deform when the loop is pressurised, so the 15 mm spacing stays constant during sustained pump operation. The hidden O-ring remains seated through thermal cycles, preventing slow leaks that can appear with softer materials. The four-piece pack covers typical multi-block layouts without requiring additional fittings.

Questions about this item

How do I install the Bitspower G1/4" Black Sparkle Extender 15mm without damaging the hidden O-ring?

Screw the G1/4" male end into the component port by hand until the hidden O-ring seats, then tighten gently with a wrench on the hex flats; over-tightening crushes the O-ring and causes leaks.

What maintenance will the nickel-finished brass extender need over time?

Inspect the black sparkle nickel finish periodically for wear or corrosion; if the surface degrades or the hidden O-ring hardens, replace the fitting to maintain a reliable seal.

What limit appears first when the extender is used in a continuous high-flow loop?

The 15 mm application length fixes the spacing between components, so the first constraint is physical clearance — if the gap changes, the extender cannot adjust.
