Yak 52 Fuel and oil Hoses

Nobody likes to be taken for granted.

Especially not the fuel & oil hoses in your engine compartment. You’d definitely want to change them before they decided to fail during a cross-country.

Although they are ‘on condition’ at your annual inspection, it would be good to have a rule of thumb for hose life - because they are mission critical, so - how many years should you expect to get out of your Yak 52’s hoses?

Here’s a document pertaining to DOSAAF operations ( lots of short student flights, multiple landings & power changes) that the total life of Yak 52 hoses, including storage is  9 Years 

The design bureau used three or four-digit hose numbers as shown below, to describe Yak hoses:

• the number of hose plies ( an indication of wall thickness),
• the internal diameter in millimeters,
• the pressure grade of the hose and finally
• the hose length, again in millimeters​

We've prepared pictures and descriptions to help you identify the hoses you need.

Certain airframe-specific hoses would be prefixed by “52” then follow a different designation if the hose had a banjo end fitting, for example. 

And if you've got a hose in one hand but the other hand is scratching your head, take a minute to check this out.
​
Anyway, whenever it’s new hose time, TYC is ready for you.  On December 1st 2019 a customer used the website to order 7 Fuel and Oil hoses, which were shipped out to him on December 3rd.

Fast enough for you ?

No parking on the dance floor, Baby.

New Russian hose material will be assembled with used, but serviceable, Metric Hose end fittings including Firesleeve where appropriate. When your shipment arrives, remove your old hose and fit the new one. 

Too easy !

But it doesn’t stop there.

​Cut the hose fittings off your old hose ( about 4" from the ends please - to give us something to grab on as we disassemble it), ship them back to us, and if they meet our ‘accept’ criteria ( see below) we’ll electronically refund you up to $15 per hose fitting upon receipt & inspection.

No need to send us modified, welded, chewed up or damaged fittings that you wouldn’t want on your plane. The two criteria we care about are:

1. Clean Hex faces. If Atilla the Crescent Wrench Avenger has visited your engine compartment, it’s not looking good for a refund.
2. A more subtle but equally disqualifying defect is Corrosion. If moisture has penetrated the hose and the fitting's protective anodizing has been compromised, unfortunately that fitting is unusable. Corrosion is rare, but we can only determine its absence by removing the old hose.

We really need your core fittings - and we need them in good shape because your formation Wingman might be our next hose customer. 

As usual, your satisfaction is guaranteed.

Please note that only stock Yakovlev hose sizes are on sale here. If you have inserted a fuel totalizer, an aftermarket Oil Filter in an existing line or switched to Aeroquip, the part numbers shown on the website are not guaranteed to fit - but we can still reproduce what you need, so email theyakcollection@gmail.com or call 619 933-2571 and talk to us.
