Hydraulic and pneumatic seals
PNEUMATIC ROD SEALS
pneumatic rod seal is a single acting sealing element made of elastomer material and has a metal ring body inside for use in open grooves
PNUEMATIC PISTON SEALS
pneumatic piston seal is a double acting piston seal designed to be used in small grooves.
HYDRAULIC PISTON SEALS
A single-acting piston seal is designed for cylinders where pressure is applied from one side only.
HYDRAULIC ROD SEALS
Rod and buffer seals maintain sealing contact in sliding motion between the cylinder head and the piston rod.
Hydraulic Wiper seal
Wiper seals maintain sealing contact to the piston rod when the equipment is stationary (static, no reciprocating motion of rod) and in use (dynamic, reciprocating rod), whereas the tolerance for the rod diameter d is determined by the rod seal.
