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.

Exact replacement fit for the Parker/Cleveland brake calipers on my A36 Bonanza. One of my calipers were showing signs of a slight leak. Replaced the leaking/old O-rings with these and no more leaks. To fully service the Cleveland caliper on an A36 Bonanza you will replace two of these O-rings. You will need 4 O-rings if you are servicing two calipers.

--quick delivery, tracking, --individually packaged o rings, manufacture date and specs on each envelope. --i also ordered from another company, (original manufacture of the hydraulic swivel), to ensure product delivery during covid pandemic. i did not use the other product eventhough i paid for a faster priority delivery, and it arrived a day sooner, with ups, those rings were all in one bag and appeared to have been produced 9 years ago, and were more expensive. also a third possible source, a local hydraulic supply company wanted 6 times more money then aircraft spruce, which had to be shipped frim another state, for the same o rings, of unknow origin, quality and specs. i did not order those. --aircrat spruces product looked better and i had the confidence of manufacture date. --the o rings i replaced failed from age, not wear. the hydraulic swivel containing them was difficult to remove and install. they work well and i have the confidence they will last another 20 plus years. the original ones lasted 50 plus years.

This is the o-ring that keeps the hydraulic oil in your brake calipers. Keep plenty on hand. Pay either 87 cents for this one or $22.70 apiece for the ones from Cleveland.

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.

Correct ring for use on this valve assembly. No leaks detected after use and long flight to Texas. Previous attempts at stopping a very slow leak were unsuccessful.

Perfect fit to repair a leaky brake cylinder on my RV8A. Much cheaper than the Cleveland part, too.

This purchase was an experiment. I needed a seal for my 2005 Subaru Baja engine oil cooler. The site is excellent and well organized. I was able to measure the ring land and easily locate an exact fit. I could not find another site at this price point to quickly find what I needed.

These o-rings come in a plastic bag which includes a cure date. So you can know how old they are. Very handy.

Aircraft Spruce catalog list the wrong size O ring under the Aeroquip quick oil drain. I did not catch the error until I received my order. I called customer service but they were no help. Then I was transferred to sales where the error was confirmed and the correct O ring sent no charge.
