John Guest PI Series Acetal Fittings
John Guest Super Speedfit Fittings
The John Guest (R) PI Range of inch-size push-in fittings are offered for tube sizes 5/32" O.D. to 5/8" O.D. The fittings are manufactured in gray acetal copolymer with food grade nitrile O-ring, making them especially suitable for applications involving foodstuff and potable liquids. They are especially suitable for air and inert gases and can therefore be used on CO2 lines, pneumatic applications and vacuum.
How Super Speedfit Fittings Work
To make a connection, the tube is simply pushed in by hand; the unique patented John Guest collet locking system then holds the tubing firmly in place without deforming it or restricting flow.
To disconnect, ensure that the system is depressurized, push the collet square against the fitting. With the collet held in this position the tube can be removed. Chemical Compatibility ChartJohn Guest Fluid Products Catalog
