AccuAir 3/8" DOT/PTC Fitting Kit (AA-3646)

If you are installing airlines on your air suspension kit, there are a few things you are going to need to make sure you get the job done correctly. Luckily, AccuAir has put together a quick and easy kit to make sure you get high-quality airlines, fittings, and a water trap to keep moisture out of your air suspension system. This kit will include a ⅜” DOT/PTC fitting kit, 50 ft of DOT airline, ¼” NPT for air springs, and an aluminum filter/trap.

Black Moisture Trap / Filter w/ (2) Fittings
In an air suspension system, you will have 1 or 2 air compressors that generate air to be delivered throughout your components. As with any air compressor, moisture can generate in the airlines, sending water droplets through the lines. This is not something that you want in any air system, so a moisture trap/filter should be installed. Air suspension water traps filter out moisture and debris from the air that gets passed through them. This AccuAir black moisture trap/filter and fittings kit gives you everything you need to ensure your system stays moisture free. In this kit you will receive a black moisture trap/filter and two fittings to install the filter on your system.

Where Do You Put The Water Trap On An Air Suspension System?
The moisture trap or water trap should be located after the tank and before the valves. This allows any condensation that was located in the tank to be stopped from getting to your valves. Stopping moisture from getting to your valves is important to keeping your air suspension system functioning properly.

Fitting Kit
Accidents happen, especially during the installation of parts where a simple mistake can cause a part to break. AccuAir knows that not every install can go perfectly, so we offer replacement parts to make sure that you can complete your install with hard to find kit components to replace damaged parts. Whether you are installing new fittings on a new install or replacing old/damaged fittings on an existing kit, AccuAir has you covered with this direct replacement fitting kit. This kit is going to feature everything you need to install new fittings on your air suspension system. In this kit, you will receive (4) 3/8" Tube DOT / PTC - To - 3/8" Tube DOT / PTC Bulk-Head + (8) 3/8" Tube DOT / PTC - To - 3/8" Tube DOT / PTC Swivel Elbow.

3/8" DOT Airline For Air Suspension (50 FT)
Whether you are planning to tackle your air suspension yourself, or you simply need to repair some damaged lines on your existing kit, you are going to want to buy your airline in bulk. AccuAir offers 50ft of ⅜” DOT airline for you to purchase to complete or repair your air suspension system. This airline is DOT approved and is made of high quality materials to allow for years of reliability. Purchase this airline in this 50ft bulk kit to save money when compared to buying airlines in smaller quantities.

Loctite 565 Anaerobic Thread Sealant (6ml tube)
Known for being the best thread sealant to use for air suspension components, Loctite 565 Anaerobic Thread Sealant is available through AccuAir to allow you to add to your order to get your system installed correctly. This thread sealant should be used to seal all NPT style fittings on your system to ensure you have a leak-free install. This PST pipe sealant has controlled strength, is made for metal fittings, and it lubricates with PTFE. This .20 fl. oz. bottle will be enough to get all of your air system fittings sealed up.
