  • 15mm overall height with threads for tight spacing
  • Brass construction resists corrosion in non-aluminium loops

Extension Coupler for Custom Loops

The Bykski G 1/4in Male/Female Extension Coupler adds 10mm of spacing between G 1/4in threaded fittings. It suits builders who need extra clearance when routing tubing in a custom liquid-cooling loop. The brass body features diamond knurling for grip during assembly. This part is intended for non-aluminum loops only.

Solving Clearance Gaps

The coupler replaces a direct fitting-to-fitting connection when components sit too close together. It is worth adding when a reservoir, block or radiator port needs a short standoff to avoid interference. The 15mm overall height with threads provides the extension without a long rigid tube run. It does not suit loops that require aluminium-compatible components.

Installation Notes

Thread the male end into the component port and the female end accepts the existing fitting. Hand-tighten the knurled brass body; over-tightening can damage threads or the internal finish. The supplier warns that the internal finish may react with DI water coolants and is not compatible with PrimoChill Opaque or VUE coolant series. Use at your own risk.

Questions about this item

How much clearance does the 10mm extension coupler add between G 1/4in fittings?

The coupler adds 10mm of height without threads and 15mm including the threaded portion, giving extra space for routing or clearance issues.

What is the correct way to tighten the brass coupler so the diamond knurling grips without stripping the G 1/4in threads?

Hand-tighten the knurled body until the O-ring seats, then give a slight quarter-turn with fingers only — over-tightening with tools can deform the brass threads.

When should the coupler be replaced if the loop uses coolants other than DI water or PrimoChill Opaque and VUE series?

Inspect the internal finish annually; replace the coupler if discoloration, plating wear or coolant residue appears inside the thread channel.
