Custom AN20 Hose Features

AN20 Hose

Choose stainless steel braided if you're looking for the highest pressure rating and maximum abrasion resistance. Alternatively, the black nylon cotton braided option offers a sleek, modern look and is slightly more flexible and lightweight than the stainless steel braided. Whichever braiding you choose, they both have the same reinforced rubber inner core, which delivers consistent and reliable oil and coolant transfer.
Bespoke AN20 Fittings

AN20 braided hoses tailor-made to your exact specifications. Choose from various AN20 fittings available in different angles, or choose a hose finisher for a neat way to terminate an open-ended hose. You can also add optional adapters to the fittings for a seamless integration into most AN20 hose systems.
360 Degree Swivel Fittings

All our AN20 braided hose fittings feature a 360-degree swivel design, allowing you to easily rotate and align the fittings to any orientation you need.

Why AN20 Braided Hoses from Custom Hoses?

Proven Under Pressure

Our AN20 braided hoses are designed to perform in high-pressure and high-temperature motorsport environments. Our pre-made braided hoses deliver consistent performance, even under the most demanding conditions.
Expertly Assembled

We have over 15 years experience and each hose is professionally assembled and quality checked to ensure reliable fluid transfer. If you're not 100% confident assembling your own braided hoses from individual parts, let us take the worry away from you. We also use custom aluminium tools to make sure the aluminium hose fittings stay unmarked and scratch-free.
No Leaks, No Worries

Our AN20 hose fittings feature a modern, tapered screw design that ensure a secure, tight seal without damaging and cutting into the hose, unlike cheaper AN20 hoses elsewhere.
Strength Meets Style

Our braided hose design not only looks great, but it provides a durability that ordinary rubber hoses simply can't match. The hard-wearing anodised black aluminium hose fittings also look the part in any fluid system.

Frequently Asked Questions

Are your custom AN20 lines covered by a warranty?
Yes, our custom AN20 lines include a 2-year warranty as standard. This warranty covers any defects in materials or workmanship.

Yes, we offer a 100-day hassle-free returns policy for these AN20 lines. We know mistakes can happen and we want to make sure you are completely satisfied. However, please double-check your choices before ordering to avoid any silly mistakes, it does cost us to replace them!
Can I use AN20 hoses for oil, fuel, and coolant?
Yes, AN20 hoses are designed to handle a variety of fluids, including oil, fuel, and coolant. They are commonly used in automotive and motorsport applications for these purposes due to their durability and reliability.
Do AN20 hoses require special tools for installation?
Our custom hoses don't need any special tools for installation. All braided hoses arrive ready to fit and can be installed using basic tools.
Do the hoses require regular maintenance?
AN20 hoses are generally low maintenance, but it's a good idea to inspect them regularly for wear and tear, especially if they're exposed to high temperatures or pressures.
How long will my custom AN20 hoses last?
The lifespan of your custom braided hoses depends on how they're used. With correct installation and regular checks they can last for years, even in harsh conditions. For your peace of mind, our 2-year warranty also protects against material or workmanship defects.
How to make custom AN20 lines?
Our custom braided hose builder makes designing your custom hoses a breeze. Simply choose your hose fittings, add adapters and banjo bolts if needed and finally, choose your hose length and heatsleeve if you need it. We'll start assembling your hoses as soon as we receive your order.
How do I measure the hose?
The easiest way to measure your custom hose is with a piece of flexible wire or sturdy string. Make sure you go around all objects and follow all curves to make sure you don't measure the hose too tight, or the hose will be stretched when you fit it. You need to measure from the seats of male and female fittings and from the center of the hole on banjo fittings. Refer to the two vertical lines on the hose builder diagram when building your hoses as the length measurement will change depending on the chosen fitting.
How are your AN20 hose fittings attached to the hose?
Our braided hose fittings feature a modern, tapered screw design for a tight, leak-free connection. First, we slide the fitting collar onto the cleanly cut hose, then with the hose secured in an aluminium vice, we use an aluminium spanner to screw the nut end of the fitting into its collar. We're very careful not to over tighten as this can crack and damage the fitting.
Are your custom braided hoses suitable for track use?
Our custom AN hoses have been tested and trusted at the highest levels of motorsport, including British Touring Cars and Drift Masters
