Description

The PSP piston seal has been designed for single and double action pneumatic cylinders. The deep groove between the dynamic and the static lip, together with back-to-back lips radius, enhance seal sliding, even where there is a lack of environmental lubrication. The reduced dimensions, together with the high flexibility of the material, also facilitates installation in closed grooves. Standard compound reference: B0 Alternative compound reference: A0 It is important to remove flashes or cutting edges in the housing to avoid damages. The rod must not have flashes and must present a lead-in chamfer (see page 153).
