Description
Mining piston seal (BMN) consists of a polyurethane sealing ring, a NBR/FKM O-ring and a backup rings. Sealing ring has sealing function, elastomer provides elasticity and compensate for wear and tear, backup ring can prevent seals to be squeezed out of groove.
Materials
Sealing ring PU (95A, red color)
Elastomer NBR/FKM
Backup ring POM
