Overview

O-rings give effective sealing over wide ranges of pressure, temperature, and movement, with the advantage of sealing pressure in both directions and reducing friction and wear on moving parts. The use of O-rings as gaskets or static seals permits metal-to-metal contact and allows almost unlimited pressures under extreme vibration.

All O-rings should be lubricated before installation and constant lubrication should be provided for running seals to avoid excessive wear. Avoid sharp edges, threads, and cross-drilled ports over or through which rings must be installed. AN6227B and AN6230B O-rings are manufactured to Spec. MIL-P 25732 for use in hydraulic systems using MIL-0-5606 hydraulic oils. MS28775 O-rings meet Spec. MIL-P- 5510A and are suitable for MIL-0-5606 hydraulic fluid at 160 F.

Reviews

The MS28775-xxx / AN6227B-xx are the hydraulic fluid resistant O-Rings that I use in the brake system of my Beech 19A. Each O-Ring comes in its own separate well marked bag - hence they store / age well and you know that what they are and that they are new.

I have not utilized the O rings as of yet, but they look good and will replace old/worn out O rings in the engine baffles.

They are round, flexible, and new. They prevent hydraulic fluid from leaking better then old, stiff, oval ones.

Q&A

Q: Can these O rings be used in fuel cells with 100LL fuel?

These o-rings, AN6227B series, are not fuel resistant. For fuel resistant o-rings, see the MS29513 series. MS29513 are aviation fuel resistant, but not resistant to automotive fuel. Search for MS29513 on our web site to find the page with the fuel resistant o-rings.
