- 9266-75 Meets Your Needs
Exceeds AMS 7276 Parco O-rings made from our 75-durometer fluorocarbon compound 9266-75 exceed the requirements of AMS 7276 (see test report on reverse side). Our compound is also on the Department of Defense Qualified Products List (QPL). Parco supplies seals to 28 military and aerospace specifications. Our quality system is certified to ISO 9001, ISO/TS 16949, AC7115, and AS9100. So when you specify 9266-75, rest assured that you’ve made the right choice.
Excellent Resistance to Compression Set To peform 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 9266-75, better maintains its elastomeric properties and original thickness, preserving seal integrity. Seals made from Parco’s 9266-75 compound provide excellent resistance to compression set (see Figure 1). After testing 9266-75 for 22 hours at 392°F, it had a compression set of only 3 percent.
