--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.

Mil Spec...are there any better?

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.

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.

excellent service

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

No Leaks!!!!

Order received as ordered on time and in new condition.

The O-rings were the correct ones as per the advice of the sales associate and they worked perfectly. Thanks.

O-rings are O-rings not much to be said about them — But your service on this and several previous orders has been just “OUTSTANDING� blindingly fast and always accurate....even on small orders — thank you Wally

Great

Fast delivery

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.

Great jumping Jehoshaphat!! What a really great O ring. Its black and round and the right size!!

Always a please doing business with yall keep up the good work and Merry Christmas... Rick

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

It was perfectly round.

Delivered quickly and on time

Great product, easy ordering.

If you have a older Beech Debonair this fits the emergency gear extension hand crank seal .

It Arrived lov.flk.

Nice ladies always helpful. lov.flk.

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.

Nicely labeled, well packaged, and fresh dates. Just what I needed at the time I needed them.

Super Customer Care

Best deal in town! I changed out o rings in both of my cng trucks and have extras for emergencies too.

Shipping was fast and it was the correct part

Wow! They were circular and made of rubber. They also fixed my brake problem. What more can you ask for?

Great product.

Works as advertised . Sky King

O-rings individually wrapped and sealed to extend their life with composition, date and size insure these are AN/aircraft approved quality

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.
