Historically, technology to produce large diameter molded O-Rings has been limited by press and molding capabilities. Parker’s properietary 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. It’s physical properties, which differ to some degree from the rest of the ring, can affect a seals reliability. A twisted or fatigued splice, for example, can open, creating failure, leakage and contamination issues.
Our homogenous molding technology is recommended for use in any large diameter O-Ring. Groove where spliced or serpentine molded rings - may present realiability issues. It has applications in virtually every market including: aerospace, chemical processing, energy oil and gas (EOG), industrial, semiconduction processing and many others.
