This airline is a longer 42" extended version of the 36" line that comes standard with the Valken SLP QD Air Rig 36"-Black #78846. This is a low pressure wide bore airline that is not only flexible and durable, but is compatible with most self sealing QD connections used in Airsoft . It is enclosed in a dual layered nylon sheathing that will not affect it's flexibility but will help protect it from damage.
Dual Quick Disconnect has a male quick disconnect fitting on one end and a female quick disconnect fitting on the other end. You will need to choose a regulator adapter if you are upgrading from a standard air rig and use this adapter to replace the existing fitting on your regulator. This allows you to quickly swap lines or disconnect your line from your air rig, which simplifies the process of taking your tank out of your back pack. You can even leave your line weaved through your gear!
