Stuffing Box Rings

In all 2-stroke diesel engines, the rod stuffing box is a vital isolating device. It helps to maintain the integrity of the crankcase by fully separating it from the combustion chamber.

Sealing rings and scraper rings perform a key function in preventing crankcase oil being contaminated with acidic combustion products and other combustion residues.

SPR is a recognised leader in the supply of quality marine diesel engine piston rings, and for many years has been supplying rod stuffing box rings and parts for piston cooling glands.

SPR offers a wide range of sealing rings and scraper rings for many engine types. Traditionally machined from bronze or cast iron, these materials enhance rings' wear resistance and conformability performance, as well as adding to cost-effectiveness.

Materials and Manufacturing Excellence

The significance of the materials used for rod stuffing box rings cannot be overstated - after all, the rings' working environment is extremely harsh. That is why SPR so closely controls the quality of all its products.

Customers can be sure that SPR's rings are not only the best available but that sizeable technical resources are being devoted to ensuring that the latest materials and technologies are always being utilised.
