Marine Purifier Seals & Gasket Kits

Prevent leaks and maintain optimal bowl pressure with our professional-grade Purifier Seals and Gasket Kits. Engineered to withstand high rotational speeds, extreme temperatures, and aggressive fuel/lube oils, these seals are the primary defense for your separation system. Sourcing Marine stocks thousands of high-durability seals for Alfa-Laval, Mitsubishi, and Westfalia units, ensuring your purifiers remain in peak condition during every watch.

  • Premium Elastomers: Available in NBR, Viton, and EPDM to handle varying temperatures and chemical compositions of HFO and LO.
  • Precision Fitment: Manufactured to exact OEM tolerances to ensure zero-leak performance and stable bowl discharge cycles.
  • Comprehensive Model Coverage: In-stock support for the world’s most common separator series, from legacy MAB units to modern S-series models.

Product Description

Centrifugal purifiers operate at speeds exceeding 10,000 RPM, creating immense pressure on the bowl seals. Sourcing Marine provides the high-quality sealing solutions required to prevent oil loss and water-contamination. Whether you are performing a 1,000-hour minor service or a 12,000-hour major overhaul, our seals provide the reliability your engine room demands.
