The Parker plug is used to plug a port on a Parker tube fitting (single ferrule or two ferrule), and it has machined ferrule(s) already inside. The Parker cap is used to cap off a piece of instrumentation tubing. It is a complete Parker assembly and includes a nut, a front ferrule, a back ferrule (two ferrule A-LOK fitting only), and a tube fitting body which is blank. Both the plug and cap can be pressurized in order for systems to be pressure tested to the maximum pressure rating of the system.

Parker Tube Fitting Caps and Plugs are available for fractional tube sizes from 1/16” through to 2” O.D. and for metric sizes from 2 mm through to 25 mm O.D. across a range of corrosion resistant materials.
