O-ring Overview--Parker O-rings & O-ring Products--O-rings for Wind Power Applications

Continuous Molding Technology – Large Diameter O-rings

Our homogenous molding technology is recommended for use in any large diameter o-ring groove where spliced or serpentine molded rings may present reliability issues.

It has applications in virtually every market, including: aerospace, chemical

Product Highlights:

  • Consistent properties throughout the diameter of the ring
  • Easier, more reliable installation versus serpentine molded o-rings
  • Reduced potential contamination of leakage through spliced joints

Historically, technology to produce large diameter molded o-rings has been limited by press and molding capabilities. Parker’s proprietary continuous molding technology ensures the strength and reliability of large diameter FKM, HNBR, NBR and EPDM o-ring seals. Parker’s solution eliminates the sealing performance problems sometimes found with common serpentine molding methods and spliced rings.

Spliced o-rings are a good solution for many non-critical applications. Potentially, they may be the weakest at their glued or vulcanized joints. Its physical properties, which differ to some degree from the rest of the ring, can affect a seal’s reliability. A twisted or fatigued splice, for example, can open, creating failure, leakage and contamination issues.

Applications

  • Large chambers, vessels, lids, doors and containers where spliced o-rings or serpentine rings may present reliability issues
  • Vacuum,high pressure and specialty semi-dynamic applications†
  • Anywhere the strength and integrity of homogeneous molded rings are critical for reliable seal performance 

Features and Advantages

  • Consistent properties throughout the diameter of the ring
  • Easier, more reliable installation versus serpentine molded o-rings
  • Reduced potential contamination of leakage through spliced joints
  • Material choices include basic FKM, HNBR, NBR, and EPDM materials
