Marine & Maritime Sealing
Solutions
High-Performance Seals for Marine
& Offshore Environments
Ashton Seals can supply marine parts and components for both OEM and maintenance. Our diverse, high quality and reliable sealing solutions supported by leading technical knowledge makes us the first port of call for marine applications.
From commercial vessels and offshore platforms to naval and
marine engineering systems, our seals deliver reliable performance,
corrosion resistance, and long service life in the harshest environments. Our flexible manufacturing operations means our gasket department can produce standard or one-off parts in both low and high volumes.
Sealing Solutions for Marine Applications
We provide sealing solutions for a wide range of marine and
offshore systems including:
Ships, vessels, and marine engines
Offshore platforms and subsea equipment
Hydraulic systems and fluid transfer systems
Propulsion and steering systems
Deck equipment, hatches, and enclosures
These applications require robust sealing
solutions capable of maintaining integrity under pressure, movement and
continuous exposure to seawater.
Resistance to Saltwater, Pressure & Harsh Conditions
Marine environments present some of the most demanding
conditions for sealing components:
Continuous exposure to saltwater and corrosion
Extreme temperatures and UV exposure
High pressure in hydraulic and subsea systems
Mechanical stress from vibration and movement
Effective sealing solutions help:
Prevent water ingress and leakage
Protect critical components from corrosion
Maintain system pressure and efficiency
Reduce maintenance and downtime
Standard marine seals typically operate within
defined temperature ranges, but specialist materials can be engineered for extreme
conditions such as sub-zero environments or high heat exposure.
Regulatory & Quality Standards
ISO 9001:2015 – Quality management systems (consistent
manufacturing quality)
ISO 6149 – Hydraulic sealing connections for high-pressure
systems
UK Marine Equipment Regulations (MSN 1874) – Safety and
compliance for equipment onboard vessels
These standards ensure sealing components are fit
for purpose, safe for marine environments, and compliant with international
maritime regulations.
Products for Marine & Offshore Applications
We supply a comprehensive range of sealing products suitable
for marine environments including:
These products are widely used across hydraulic systems,
propulsion systems, deck equipment and structural components.
Materials & Performance
Marine sealing solutions must be designed for durability and
reliability.
We offer materials that provide:
Resistance to saltwater corrosion and marine environments
Compatibility with oils, fuels, and hydraulic fluids
Durability under pressure, vibration, and mechanical stress
Resistance to UV, ozone, and temperature fluctuations
Common materials include:
NBR and HNBR – for oil and fuel resistance
FKM (Viton®) – for high temperature and chemical resistance
EPDM – for water and weather resistance
PTFE – for low friction and long service life
Typical Applications
Our sealing solutions are used across a wide range of marine
systems:
Hydraulic
pumps and cylinders
Propulsion
and steering systems
Engines
and fuel systems
Hatch
covers and watertight doors
Subsea
and offshore equipment
These applications require reliable sealing to ensure
safety, efficiency and compliance at sea.

Frequently Asked
Questions
1. What seals are used in marine applications?
Common sealing solutions include O-rings, hydraulic seals,
rotary shaft seals and gaskets designed to withstand saltwater, pressure and
harsh environments.
2. What certifications are required for marine sealing
products?
Marine seals may require approvals from classification
bodies such as DNV, Lloyd’s Register, and ABS, as well as compliance with ISO
and marine equipment regulations.
3. Why is corrosion resistance important in marine seals?
Saltwater environments accelerate corrosion, so seals must
protect components and maintain performance over time.
4. What materials are best for marine sealing solutions?
Materials such as EPDM, FKM, NBR, and PTFE are commonly used
due to their resistance to water, chemicals and temperature extremes.
5. Can marine seals be customised?
Yes, sealing solutions can be engineered to meet specific
vessel, offshore, or subsea application requirements.
