The PI Range of Inch-Size Acetal Quick Connect Tube Fittings - John Guest    
PI Fittings, offered in sizes 5/32 inch O.D. to 1/2 inch O.D., are manufactured in gray acetal copolymer with food grade nitrile O-ring, making them especially suitable for applications involving foodstuffs or potable liquids. They are however equally suitable for air and inert gases and can therefore be used on CO2 lines, pneumatic applications, and vacuum.
