Thermaltake Pacific M-Pro Fitting Kit

These fittings are specifically designed for 16mm outer diameter (OD) PETG hard tubing. While they may physically fit other materials, they are optimized for the rigidity and dimensions of PETG.

The triple O-ring design provides three distinct points of contact between the fitting and the tubing. This significantly reduces the risk of leaks compared to standard single or double O-ring fittings, ensuring a more secure seal for your custom loop.

Yes, all fittings in this kit utilize a standard G1/4 thread, making them compatible with the vast majority of custom liquid cooling blocks, radiators, and reservoirs on the market.

This kit provides eight essential fittings—six straight compression and two 90-degree adapters—which is a great starting point for a basic CPU-only or GPU-only loop. Depending on the complexity of your tubing runs, you may need additional adapters or fittings to complete your specific layout.

These fittings are constructed from high-quality copper and finished with a chrome plating. This material choice ensures excellent durability and helps prevent corrosion within your cooling loop.

You generally only need your hands to tighten the compression collars. However, using a soft cloth or a dedicated fitting tool can help you achieve a secure grip without scratching the chrome finish during installation.
