Polyurethane Seals

This range of polyurethane seals has been developed for both hydraulic and pneumatic use, all to fit within the ISO standard groove dimensions. However, should an application require something non-standard, our design and engineering team can provide a bespoke solution.

• Capable of up to 700 Bar (10,000 psi) depending on design
• Temperatures between -40°C to 85°C (-40°F to 185°F)
• Available in various hardness and grades
• Diameters up to 2.5m (98")

When used in hydraulic applications, either internally, externally or as U-seals, our range offers many added advantages over rubber and/or fabric reinforced.

Advantages of Fluorocarbon Polyurethane Seals

• Higher working pressures
• Longer working life (up to 50 times)
• Excellent abrasion resistance
• Better tear strength

Polyurethane seals and components offer many benefits making them ideal for the glass and metal forming industries.

Benefits Fluorocarbon Polyurethane Seals

• Non-marking
• Extended life
• Stable elasticity
• Resistance to splitting

Service

• Approval by the US Food and Drug Administration makes our seals and components ideal for food filling machines.
• Our seals are manufactured with interference already built into the sealing lips, allowing low pressure start up.
• The seals are suitable for subsea use, with materials having been approved for sea water, slurry and gases.
• Many seals and wipers in polyurethane can be offered up to 2.5 metres in diameter, suited for use in hydraulic presses.
• All our polyurethane grades have excellent hydrolysis resistance.
• We can add a number of additives to improve specific properties, such as resistance to fire, mould, mildew and fungus. In dynamic applications the inclusion of MoS₂ will help to reduce friction.
