Hydraulic & Oil Seals

Advanced sealing technologies designed to prevent leaks, block contaminants, and maintain optimal internal pressure in the most demanding industrial applications.

At Al Masder Al Jadid, we recognize that a minor leak can lead to major downtime. That's why we offer a comprehensive, high-quality range of sealing solutions engineered to withstand extreme pressures, temperatures, and aggressive chemicals. Whether you need standard rotary shaft seals (Oil Seals), durable O-Rings, or specialized hydraulic cylinder components, our vast inventory and technical expertise ensure your machinery remains fully protected and operational.

Available Types & Applications

Rotary Shaft Seals (Oil Seals)

Rotary Shaft Seals (Oil Seals)

Designed to seal rotary elements, preventing lubricants from leaking out while keeping dust and dirt from entering. Available in NBR, Viton (FKM), and Silicone.

Automotive engines & transmissions
Industrial gearboxes
Electric motors & pumps
O-Rings & Static Seals

O-Rings & Static Seals

The most universal sealing solution. Simple, reliable, and versatile for both static and dynamic applications. We supply standard and metric sizes in various compounds.

Hydraulic valves & fittings
Pneumatic cylinders
High-temperature fluid lines
Hydraulic Piston Seals

Hydraulic Piston Seals

Engineered to ensure fluid does not bypass the piston in a hydraulic cylinder, enabling maximum pressure build-up and optimal force generation.

Heavy earthmoving equipment
Industrial hydraulic presses
Lifting and handling machinery
Hydraulic Rod Seals

Hydraulic Rod Seals

The most critical seal on any type of fluid power equipment, preventing the leakage of fluid from within the cylinder to the outside.

Agricultural machinery
Construction equipment
Injection molding machines
Wiper & Scraper Seals

Wiper & Scraper Seals

Installed to scrape dirt, chips, and moisture from the piston rod as it retracts, preventing contamination of the hydraulic fluid and protecting internal components.

Mining excavators & loaders
Harvesters & tractors
Outdoor hydraulic systems
Mechanical Seals

Mechanical Seals

Highly sophisticated seals used primarily in rotating equipment like pumps to contain fluids tightly where the shaft passes through the pump casing.

Centrifugal water pumps
Chemical processing pumps
Food & beverage processing
Pneumatic Seals

Pneumatic Seals

Specialized seals designed for lower pressures and higher speeds than hydraulic seals, optimized for air applications with minimal lubrication.

Factory automation systems
Packaging & sorting machines
Pneumatic power tools
V-Rings & Backup Rings

V-Rings & Backup Rings

V-Rings act as a flinger to repel dirt, while Backup Rings are used alongside O-rings to prevent extrusion under high pressure gaps.

High-pressure hydraulic gaps
Heavy-duty industrial fans
Rotary & static support

Seal Material Guide

MaterialTemperature RangeChemical ResistanceBest For
NBR (Nitrile) -30°C to +100°C Good (Standard Oils) General hydraulics, standard engines
FKM (Viton) -20°C to +200°C Excellent (Aggressive Fluids) High-temp engines, chemical processing
Polyurethane (PU) -35°C to +110°C Good High-pressure hydraulic cylinders (very tough)
Silicone (VMQ) -60°C to +200°C Fair Extreme temperatures, static applications
PTFE (Teflon) -200°C to +260°C Outstanding Dry running, severe chemicals
