Extension coupler for custom loops

The PrimoChill Male-Female G1/4in 40mm SX Extension Coupler adds clearance between a component and a fitting in a custom water-cooling loop. It provides a single male and a single female G 1/4in thread in a coated brass body. The overall height with thread is 45mm and 40mm without. An O-ring is pre-installed on the male side.

For builders needing extra thread reach

This coupler suits anyone who finds a standard fitting too short to clear a block, radiator port or reservoir inlet. It is not intended for builders who need an angled adapter, a rotary joint or a longer extension than 40mm. It also does not replace a dedicated drain valve or a quick-disconnect fitting.

Check thread compatibility and clearance

Verify that every component you plan to connect uses a G 1/4in thread before ordering. Measure the available gap in your loop to confirm the 45mm overall height will fit without stressing adjacent tubing or fittings. Ensure the coated brass finish is acceptable alongside other metals in your coolant path.

商品問答

What G 1/4in threaded components do I already need to connect this 40mm SX extension coupler?

You need at least one male G 1/4in fitting and one female G 1/4in port, such as on a water block, radiator, pump or reservoir, to thread the coupler between them.

Will the 45mm overall height with threads fit alongside my existing G 1/4in fittings in a tight loop?

The coupler adds 40mm of body length plus thread engagement, so measure the gap between your current fittings; if the clearance exceeds roughly 45mm it will fit without forcing adjacent tubing.

How can I confirm the coated brass coupler is sealed and oriented correctly after installation?

The male side ships with an installed O-ring; hand-tighten until the O-ring compresses, then pressure-test the loop — no leaks and proper alignment mean it is working as intended.
