Custom Molded Seals

Custom molded seals are cast from molds designed for a unique set of engineering requirements, balancing manufacturing elements such as production cycles, curing and environmental factors with the function and volume of the seal.

While more expensive than standard O-rings and gaskets, custom molded seals provide many advantages for complex and critical applications, including:

• Nearly limitless sizes and geometries, designed exclusively for your specific application profile
• Excellent dimensional tolerances
• Superior leak prevention
• Ability to incorporate reinforcements, internally or externally
• Ability to add permanent tracking or other identification information etched onto the seal

Custom molded seals are precision manufactured for quality through various techniques:

• Compression molding
• Transfer molding
• Injection molding
• Liquid injection molding

Custom molded seals are used in nearly every industry and for a wide variety of functions:

• • Accumulator – used to accommodate fluctuations in system volume
  • Ball Seals – commonly used in check valves and as a bumper
  • Bladder Seal – pneumatic bladder that inflates to create a barrier seal
  • Bushing – cylindrical sleeve, often used in fluid power components
  • D-Shaped Ring – solid or hollow with a flat base, prevents spiral failure
  • Damper Seal – typically used in industrial shut-offs to minimize leakage along with modulating capability
  • Diamond Seal – extreme wear capabilities for abrasive or erosive conditions
  • Duckbill Seal – elastomeric backflow prevention component
  • Dust Cover Seal – provides a barrier against dust and other particulates, oil, grime and scratches
  • H-Shaped Ring – solid or hollow, fits straight-walled or dovetail grooves
  • Lip Seal – maintains friction and lubrication while eliminating contaminants
  • Press-In-Place Seal – one flat surface has a groove design cut into it to retain the O-ring in the gland
  • Piston Seal – split ring in a reciprocating engine to prevent fluid from flowing across the cylinder head
  • Plugs – wide variety of connectors, caps and cavity seals
  • Rubber Bellows – protective cover (dust boots or dust seals) that allows for specified range of motion
  • Self-Retaining Seal – hollow or solid, friction maintains proper sealing position in the groove
  • Trapezoid Ring – extruded shape for difficult sealing geometries
  • Vibration Mounts – absorbers or isolators made of elastomer/metal combinations
  • X-Ring (Quad™Ring) – essentially an O-ring with a four-lobed profile that offers twice the sealing surface and better gland stability
