Pacific DIY LCS Chrome Fitting

This Thermaltake compression fitting connects 13 mm inner-diameter tubing to a G 1/4 port in a custom liquid-cooling loop. The chrome-plated brass body and pre-installed O-ring create a high-flow, leak-free seal for DIY builders assembling their own water-cooling systems.

Loop Integration and Clearance

The fitting screws directly into any component with a G 1/4 thread, such as radiators, reservoirs or water blocks, and accepts 15.9 mm outer-diameter soft tubing. Its 25 mm outer dimension and 24.7 mm height keep the profile low enough for tight routing between closely spaced parts.

Tubing Compatibility and Limits

Designed for 1/2 inch ID by 5/8 inch OD PVC tubing, the fitting handles standard soft-tube sizes used in many custom loops. Builders using hard tubing, larger diameters or metric sizes not listed will need different fittings to complete their build.

Questions about this item

How much pressure can the G 1/4 compression fitting hold before it leaks under sustained use?

The high-flow, leak-free design uses a pre-installed O-ring and chrome-plated brass construction to maintain a seal at typical loop pressures.

Does the brass fitting add noticeable heat or noise when the pump runs all day?

The 55 g copper-based fitting is passive; it adds no noise and negligible thermal load to a running loop.

What tubing size must I already have for the 1/2" ID 5/8" OD compression fitting to work?

You need tubing with a 13 mm inner diameter and 15.9 mm outer diameter to match the fitting's specifications.
