NBR Rubber Gasket – Reliable Sealing for Marine Manhole Covers

In seawater piping systems and tanks, ensuring a perfect seal at manhole covers is essential to prevent leaks and water ingress.

The NBR rubber gasket is specifically designed for marine manhole covers, combining high elasticity and oil resistance to withstand the harsh conditions of marine environments. When the manhole door is closed, the gasket is compressed to form a secure barrier against seawater intrusion or leakage.

Key Features:

  • Effective leak prevention: Maintains pressure and blocks seawater penetration.
  • Oil and mild chemical resistance: Suitable for engine rooms where oil and grease are present.
  • Durable performance: Resists wear, aging, and continuous marine operation.
  • Easy installation: Fits a wide range of standard manhole covers.

Typical Applications:

  • Manhole covers on ships and offshore platforms.
  • Seawater piping systems.
  • Ballast tanks, seawater storage tanks, engine room access covers.
  • Coastal and industrial facilities exposed to seawater.

With outstanding sealing performance and long service life, the NBR manhole gasket is the trusted choice for shipbuilding, maintenance, and marine equipment operations.
