DETAILS:
The SUNRUB type UB seal is a flexible seal suited for sealing piston rod.
Theadditional o’ring profile at the bottom provides as a back-up to the mainsealing lip, providing lubrication, abrasion resistance & remains unaffectedwith varying pressures. Also available in nitrile (NBR) upto 160 BAR besidesPolyurethane for 300 BAR. Due to excellent wear resistance properties ofpolyurethane the life expected is 3 times that of NBR.
FEATURES:
Simpleinstallation.
An O’ring profile at bottom improves sealing & serves as a good back-up tothe main sealing lip. It wipes off small traces of oil that passes the sealinglip with every stroke.
