The Lee Spring catalog has always offered springs with relatively high spring rates or workable (maximum) loads. But often, the offered outside diameters were too wide to fit within the intended application assembly requirements, or the lengths too long and bulky.
The success of our Lite Pressure™ Series has naturally led to Lee Spring’s development of a “High Pressure” Series (LHP). This new “High Pressure” Series is offered so that, for a given length and outside diameter, there would exist a series of springs that had higher spring rates or workable load ratings than what is currently offered by the existing Lee Spring Standard Series compression springs.
The “High Pressure” compression series include selections to work inside holes from 1/8″ (3.18mm) to 1″ (25.40mm). They are available in a range of free lengths, starting at 0.250″ (6.35mm) up to 2″ (50.80mm).
