HYDRAULIC SEALS
In Industrial Fluid Power

A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications.
Their use is critical in providing a way for fluid power to be converted to linear motion.
What is hydraulic seal?

Based on Sealing:A] Positive seals- Do not allow any leakage.B] Non positive seals- Permits internal leakage.Based on applications:A] Static seals- No relative motion mating
parts.B] Dynamic seals- Relative motion mating
parts.Based on shape:A] O-rings B] Quad rings C] V-packingD] U-packing E] Cup packing F]Composite

Position of seals

Pressure Depending upon higher or lower pressure
situations.
Temperature Leather- below 65 c, Plastics- up to 260 c.
Operational Speed Compatibility with oil, Metal clearance,
Alignment, Metal finish, Life expected.
Factors affecting

Leather seals Tough, pliable, resistance to abrasion, wear,
stress & temperature effects. Rubbers Poor resistance to petroleum fluids & rapid
aging when exposed to oxygen or ozon. Plastics (Flouro-plastics & Flouro-elastomers) High heat resistance, compatible with fluids. Metals High pressure, easily bent, hard in compression.
