Threaded Extender for Custom Loops

This Thermaltake G 1/4 extender adds 20 mm of length between a female and a male port. It suits builders who need extra clearance when routing hard tubing or aligning blocks in a custom liquid-cooling loop.

Replaces Shorter Straight Fittings

Swap it in when a standard fitting leaves a gap that forces tubing to bend sharply or stresses a block port. The 20 mm extension is worth it only when the shorter part cannot make the connection without strain.

Chrome-Plated Brass Under Pressure

The CU body with chrome plating resists corrosion during long-term coolant circulation. A pre-installed O-ring seals the G 1/4 threads so the joint stays leak-free under sustained pump pressure.

Questions about this item

What thread size and orientation does the 20 mm extender use to join two G 1/4 components?

It has a G 1/4 male thread on one end and a G 1/4 female thread on the other, adding 20 mm between fittings.

How do I install the fitting without damaging the pre-installed O-ring?

Hand-tighten the male thread into the female port until the O-ring seats, then give a light quarter-turn with a wrench; over-torquing crushes the ring.

When should the chrome-plated brass extender or its O-ring be replaced in a custom loop?

Inspect the O-ring at every coolant change; replace the fitting if the chrome finish shows pitting or the threads feel rough.
