Chrome Fill-Port Fitting for DIY Loops

The Thermaltake Pacific DIY LCS Chrome Fill-Port Fitting is a G 1/4 threaded component designed for custom liquid-cooling builds. It accepts tubing with a 13 mm inner diameter and provides a dedicated fill port for easier loop maintenance. The chrome-plated brass construction adds a distinctive metallic finish to the loop.

Verify Thread and Tubing Compatibility

Before ordering, confirm that your existing blocks, radiators, and reservoirs use G 1/4 threads to match this fitting. Ensure your tubing inner diameter is exactly 13 mm for a secure seal. The fitting adds 26 mm of height, so check clearance around the intended port location.

Brass Body with Chrome Finish

The fitting weighs 42 g and uses a copper-alloy body with chrome plating for corrosion resistance. The G 1/4 screw thread is a standard size for custom cooling hardware. A knurled cap allows tool-free opening for filling or draining the loop during routine maintenance.

Questions about this item

What comes in the box with the CL-W038-CU00SL-A fill-port fitting, and do I need to buy tubing or coolant separately?

The box contains the single chrome-plated brass fitting with G 1/4 thread. You must purchase 1/2 inch (13 mm) ID tubing and coolant separately to complete the loop.

How do I choose between the available versions of this fitting for my loop?

This model is offered in one size: G 1/4 thread for 1/2 inch (13 mm) ID tubing. Select it when your loop uses that exact tubing size and thread standard.

What does the 42 g weight mean once the fitting is installed in a custom loop?

At 42 g the fitting adds minimal mass to the loop, keeping stress on the tubing and block low while the G 1/4 thread ensures a secure, leak-free seal.
