Safety screens offer two-fold increase in burst pressureLee Products is introducing a range of high-pressure, flange-mount etched safety screens with burst/collapse pressures that are, on average, more than double that of the existing stainless steel 304L type safety screens.

Thanks to their rugged construction using 17-7PH CRES material, these screens provide burst/collapse pressures (depending on the hole size) from 1250/100psid for the 656 flange-mount option, up to 7000/4550psid for the 130 flange-mount option. In addition to taking advantage of higher strength material properties, the screens are designed to excel in open area by utilising a pleated screen bend feature that maximises their open area or dirt holding capacity.

Available in 28 standard versions, the screens offer outstanding flexibility for applications such as aircraft hydraulic systems and engine fuel systems and are completely interchangeable with Lee's existing etched, flange-mount safety screens. They can be supplied in seven different flange sizes with diameters ranging from 0.130in to 0.656in. In addition, standard screen hole sizes include 0.004in, 0.006in, 0.008in and 0.015in. Nominal weights are from 0.05-3.1g.
