MS83461 nitrile orings function optimally in MIL-H-5606 aircraft hydraulic fluid, proving greater dynamic efficiency than MS28775 seals. Plus, it has notable resistance to petroleum-based products such as hydraulic fluids, selected silicone fluids, and fuels making it the preferred choice for aircraft mechanics.
Pilots HQ responded promptly to my order. They were delivered on time and pricing was reasonable. I would order from them again. Top notch company, very professional.
