Aircraft Accessories Corp. 31028 Relief Valve One WWII Aircraft Accessories Corp. Hydraulic Relief Valve as made to Boeing pattern Type BAC3-14684.Condition is unused and part has been warehouse stored for 70 years. Ends are protected to keep out dirt and moisture - all looks good inside. Metal data tag with Type. BAC3-14684 Part No. 31028 and the unit Serial Number 12264805 as made by Aircraft Accessories Corp. of Burbank, CA.Supported by a military yellow parts tag with similar information and inspection date of April 15 1954. The military put a prefix of 4806 in front of the p/n of 31028 on the tag. Came in a box of Boeing B-17G spares we'd acquired awhile back that contained some of the limited hydraulic systems for the airplane - the cowl flap actuator, some brake metering valves and pressure switches for the hydraulic management panel. These are similar relief valves to the earlier ones on some of the B-17 panels I've worked on. I do not know if this similar type of relief valve system was used on the B-29 or B-50, but suspect it might have been as Boeing did use some similar components in different product lines of same era.Beautiful NOS condition. New Old Stock (NOS) and never used as judged by plastic port protective ends. It had been shelf stored for years. Great paint, no improper storage wear and tagged. Whatever the case, this is a good candidate for cleaning, inspection and re-use or for a display in a restoration project. Weighs about a pound.What you see in the photo series is representative what you get. Ships cheapest USPS Priority Mail or Parcel Post unless you request otherwise. Questions? Please ask seller. And thanks for looking!
