Marine Piston Rod Stuffing Box Assemblies

At Sourcing Marine, we specialize in high-performance Piston Rod Stuffing Box Assemblies, a critical component for maintaining the separation between the combustion space and the crankcase in 2-stroke crosshead engines. A poorly maintained stuffing box leads to excessive system oil consumption and potential crankcase contamination.

  • Swiss-Engineered Sealing: Utilizing original Swiss non-metallic packing to minimize rod abrasion and optimize oil scraping efficiency.
  • Immediate Stock Availability: Complete assemblies are ready for rapid global dispatch, minimizing vessel downtime during overhauls.
  • Total Maintenance Savings: Reduced friction translates directly into lower system oil loss and fewer required piston rod re-grinds.

Product Description

Our solution goes beyond standard replacements. We offer Complete Stuffing Box Assemblies in stock, featuring Swiss-made non-metallic packing sets. These advanced materials are specifically engineered to provide superior sealing while significantly reducing friction and wear on the piston rod. By upgrading to our non-metallic components, shipowners can achieve longer service intervals, reduced spare parts costs, and extended equipment life.

Full Component Inventory

We supply both complete housing assemblies and individual repair kits, including:

  • Sealing Rings & Scraper Rings: High-precision profiles for maximum gas and oil separation.
  • Scraper Plates & Guide Rings: Engineered for stable rod alignment.
  • Tension Springs: Calibrated for consistent radial pressure throughout the service life.
  • Lock Washers & Specialized Hardware: Ensuring secure internal fitment.
