Features include: 
These
 gas manifolds are rated to 100psi and include 2 gas line outputs and 2 x
 1/4inch ball vales. 
Made complete from aluminium, brass and stainless so they are durable. 
Includes screw holes at the top for easy mounting to your gas board. 
Each ball valve has a built in check valve to not only protect your 
regulator but also prevent gas or beer migrating from one keg to 
another. 
Please note that due to the check valve mechanism there is about a 2 psi
 pressure drop over the ball valves in these manifolds. 
You will need to
 set the pressure on the regulator about 2 psi higher than the desired 
pressure in the keg.
Ensure that you only use the best equipment for your home brewing!!
