The chain is of the type Seal Pro, with a unique O-ring design that seals the rivet joints of the chain, keeping the abrasive materials out while letting the lubrication in. This produces excellent chain life at a minimum water pressure. All chains are supplied with a nine-toothed driving wheel that fits the Husqvarna K 950 Chain.
PXC 45 is used for hard material, such as granite or hard brick. Item No. 531101185
