Bykski G 1/4in 40mm Extension Coupler

This Bykski extension coupler adds 40mm of length between two G 1/4in threaded components. The brass body features diamond knurling for grip and a white finish. It threads directly into any standard G 1/4in port to create extra clearance in a custom loop.

Suits builders needing extra thread reach

The part is designed for non-aluminium loops only. The internal finish may react with DI water coolants and is not compatible with PrimoChill Opaque or VUE coolant series. Buyers using those fluids or aluminium components should choose a different fitting.

40mm extension length decides fit

The coupler measures 40mm without threads and 45mm including them. This single dimension determines whether the gap between your blocks, radiators or reservoirs can be bridged. Measure the space you need to close before ordering.

Questions about this item

How much clearance does the 40 mm coupler add between G 1/4 in. fittings?

The coupler adds 40 mm of clearance between components, with an overall height of 45 mm including threads.

Which tool and torque should I use on the diamond-knurled brass body?

Hand-tighten the knurled brass body until the G 1/4 in. threads seat firmly; avoid pliers to prevent marring the finish.

When should I replace this brass extension coupler?

Replace it if the threads strip, the O-ring degrades, or you switch to DI-water or PrimoChill Opaque/VUE coolants that the finish does not support.
