Lee Cross Port Plugs

Lee Cross Port Plugs are a plugging solution specifically engineered to seal cross port passageways. This configuration is a variant of the original Lee Plug® that set industry standards over 65 years ago. A smooth wall design combined with the field-proven controlled expansion principle creates a permanent, leakproof seal, without the need for o-rings or sealants. Installation is simple,...

Lee FLOSERT® Miniature Flow Regulating Valves

Lee Floserts are pressure compensated flow control valves that provide a constant flow over a wide range of differential pressures. The Flosert operates by sensing the flow rate in terms of a differential pressure across a fixed orifice. A variable metering orifice then automatically adjusts to keep this pressure, and thus the flow rate, constant. Lee Floserts are useful for controlling the...

Lee HI-BAR® In-Line Wash Flow Safety Screens Take Filtration to a Higher Level

The Challenge Protecting components from contamination is essential in critical fluid control applications, such as those found in the aerospace, power generation and automotive industries. While many systems are designed to be relatively immune to low levels of small size contaminants, single larger rogue particles can cause blockages which could result in system failure and downtime. The...
