Soft Tubing Pros and Cons

Even though soft tubing is considered to be the beginner’s option, we cannot claim that it’s that much easier to use than hard tubing. Some bends are just impossible to pull off with soft tubing. We discussed various types of tubing in our Fittings and Tubing Guide, where we mentioned the kinking effect on soft tubing. It has a mind of its own and tends to go its own way. If you make a bend too tight, the tube will collapse and stop the coolant flow.

No Kinks in Soft Tubing With FF Adapter Fittings

EK-Quantum Torque 45° and 90° Angled Adapter Fittings are limited to certain requirements and situations. Still, they offer the needed flexibility when building your loop, whether using soft or hard tubing.

90° Adapter Fittings for Easy Loop Building

Angled FF adapter fittings, however, can be really helpful when basing your loop on hard tubing. They can be used to avoid bending tubes altogether or to make fewer bends.

Understanding the Fittings’ Naming

First off, what does FF, 2F, or Female-Female mean? Fittings are often marked or described by several key specifications. The type of thread they use, G1/4″, is the widely accepted standard in liquid cooling. If it’s an angled adapter fitting, the angle will also be specified. So, either the name or description of the fitting itself lets you know the type of the G1/4″ thread, i.e., whether it’s Male or Female.

Make Bends Without Bending

This brings us to our new 45° and 90° angled 2F adapter fittings, where the “FF” marking means it has female inlets on both sides. Tight bends don’t have to be tight anymore! Even with hard tubing, which has the advantage over soft tubing, you are otherwise restricted to a specific tube bending radius.

By using an FF angled adapter fitting, you are eliminating the radius of the bend, and therefore, it becomes possible to make bends without the actual tube bending.

Unique Tube Runs in Water-Cooled PC Build


Whether you use hard or soft tubing, bend the hard tubing yourself, or opt for angled adapter fittings, it usually comes down to personal choice and aesthetics. You can get the same result with a different approach. The use of FF angled adapters is not dictated solely by your needs. It’s something you can choose to make your build look distinctive and unique.
