Parker's E1244-70 Compound - USP Class VI and USP <87> Internally Lubricated EPDM

Parker compound E1244-70 contains an internal lubricant that reduces installation force and dynamic friction without the need for an external lubricant.  The proprietary internal lubricant in E1244-70 is derived from the  fatty acid family, making it unlikely to cause a patient reaction.  Successfully completing USP Class VI and USP <87> testing further demonstrates the safety of this internal lubricant.

External lubricants are messy and migrate into areas where they are not needed, possibly into flow paths where they can affect patient health.  Even “clean” lubricants like USP grade silicone quickly trap dirt and dust that can harbor bacteria. 

E1244-70 Benefits

  • No external lubricant required
  • Excellent resistance to repeated steam, gamma, ozone, and ehylene oxide sterilization
  • Compliant with USP Class VI biocompatibility standards
  • Compliant with USP <87> cytotoxicity standards
  • Low compression set
  • Low friction/low wear
  • Temperature range -65 to 250 F
  • Compatible with all water-soluble chemistries

Parker E1244-70 for Dynamic Motion on Rubber Seals

In medical devices and pharmaceutical manufacturing applications that involve dynamic motion on rubber seals, small amounts of external lubricants are commonly used to control the friction. Operating seals in a dry condition leads to friction, heat buildup, and accelerated wear that can generate rubber particle contamination or result in leakage. In addition, many applications require lubrication for installation to prevent seal damage.  Installing seals without lubrication can also result in improper assembly, operator fatigue, and repetitive stress injuries.

E1244-70 Applications

  • Dynamic applications
  • Surgical instruments
  • Pharmaceutical manufacturing
  • Biopharmaceutical processing
  • Disposable medical devices
  • Repeated device sterilization
  • Difficult installations
