Profile : Rod Seals


Spareage : S21
S21 Assembly
 
Details :
S21 is a symmetrical single acting seal offering excellent dry rod sealing for both light and medium duty applications. The additional O-ring profile at the bottom provides a back-up to the main sealing lip, providing lubrication, abrasion resistance & remaining unaffected with varying pressures. Standard material for S21 is Polyurethane but we can also supply in NBR material (on request). Due to excellent wear resistance properties of polyurethane, the life expected is 3 times that of NBR.
