- 4457-65 Meets Your Needs
Exceeds AMS-P-5315 Seals made from our 65-durometer nitrile compound 4457-65 exceed the requirements of AMS-P-5315 (see test report on reverse side). Parco supplies seals to 28 military and aerospace specifications. We are also one of only a few manufacturers approved to supply Qualified Products List (QPL) rubber seals. Our quality system is certified to ISO 9001, ISO/TS 16949, AC7115, and AS9100. So when you specify 4457-65, rest assured that you’ve made the right choice.
Excellent Resistance to Low Temperatures Seals used in low temperatures may become hard and brittle, making them more susceptible to cracking. Parco’s 4457-65 seals can be used in static sealing applications with continuous service temperatures as low as -65°F. The excellent lowtemperature properties of 4457-65 seals enable them to resist cracking in low-temperature applications.
Outstanding Resistance to Compression Set To perform properly, most seals must resist taking a set from compression after being installed. When a seal takes a set, it no longer exerts force on the mating surfaces, resulting in leakage. A compound with low compression set, like 4457-65, better maintains its elastomeric properties and original thickness, preserving seal integrity. After testing 4457-65 for 22 hours at 212°F, it had compression set of only 9 percent.
