Aquaseal Watertight Hatch Seal


Aquaseal Rubber Ltd first developed our flagship product – the Aquaseal Hatch Seal – when manufacturing watertight hatch seals over 40 years ago. Since then, we have continued to provide our Aquaseal Hatch Seal to leading hatch cover suppliers worldwide.

About Aquaseal Hatch Seal
Aquaseal is a watertight hatch seal used primarily for marine hatch packing and door seal applications. The seal consists of a solid rubber outer on 3 sides and a cellular sponge core bonded to the solid rubber outer faces.

Depending on your application, there are three choices of rubber for the sealing face:

  • General-Purpose Use: Natural Rubber/SBR
  • Ozone Resistance & High-Temperature Use: Neoprene Rubber
  • Gas & Oil Resistance: Nitrile Rubber



The cellular core is purpose-made for this product and offers excellent compression recovery. We offer several standard sizes:

  • 38mm x 25mm
  • 40mm x 20mm
  • 71mm x 32mm
  • 94mm x 50mm

However, we can manufacture our Aquaseal Watertight Hatch Seal bespoke in a variety of sizes from 20mm x 20 mm up to 150mm x 55mm. Speak to a member of the Aquaseal team today to discuss custom sizing and prices.

Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber compound that consists primarily of ethylene and propylene. Aquaseal Rubber uses EPDM synthetic rubber compounds for both general and specialty outdoor applications, including steam hoses, high temperature-resistant seals, electrical insulation, roll covers, and more.

Styrene Butadiene Rubber

Styrene-Butadiene Rubber (SBR) is the most common and economical synthetic rubber compound available and is used in a broad range of industrial applications. Because SBR’s properties are also similar to natural rubbers, styrene-butadiene rubber can replace natural rubber in many products.
