- 4367-70 Meets Your Needs
Exceeds AMS-P-83461
Seals made from our 70-durometer nitrile compound 4367-70 exceed the requirements of AMS-P-83461 (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 4367-70, rest assured that you’ve made the right choice.
Outstanding Resistance
to Low Temperatures Seals used in low temperatures may become hard and brittle, making them more susceptible to cracking. Parco’s 4367-70 seals can be used in static sealing applications with continuous service temperatures as low as -65°F. The excellent lowtemperature properties of 4367-70 seals enable them to resist cracking in low-temperature applications.
Outstanding Resistance to High Temperatures
High temperatures can cause seals to undergo irreversible chemical changes, reducing 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. 4367-70 seals are peroxidecured, offering improved resistance to high temperatures over other low temperature nitrile compounds. 4367-70 seals can resist temperatures up to 275°F

- Applications
Parco’s 70-durometer nitrile compound 4367-70 is ideal for use in applications with exposure to both low and high temperatures. Seals made from 4367-70 can be used in dynamic sealing applications with continuous service temperatures as low as -61°F and as high as 275°F. 4367-70 offers excellent service with gasoline and military aircraft hydraulic fluid. Seals made from 4367-70 should not be exposed to automatic transmission fluid, hot air, or ultra violet light.
