Bosch VP37 Injection Pump Head

Hello.
I have a question.
wo bekomme Ich die Dichtung für den Pumpenkopf einer Bosch VP 37 ev. E-NR
It can't be right that you can only get this sealing ring from Bosch.
With the correct dimensions, it should also be available from the manufacturer of the seals (I only need the seal itself, but I don't have the dimensions).
Bosch part number: pump 0460 404 971 R 510-3 BT 4015.
Audi No: 028 130 115 W
The vehicle is an Audi A4 B5 1.9 TDI, 90 kW, manufactured in 1998, with engine code AHU.

Thank you in advance for your reply.

Hi,

"You can find this type of gasket at Bosch for about 15 euros."
What's the problem? You might as well replace the other seals while you're at it.

Regards,
Adrian.

Okay, I understand. I just want to seal the pump head; the rest is still sealed. And it doesn't make sense to throw away the remaining seals.

Best regards,

Then, just keep the rest as a reserve, in case something else starts leaking.

Hello.

The large O-ring for the pump head measures 59x2.5mm.

A single piece of seamless NBR rubber costs approximately 3 euros.

It is resistant to the bio component in diesel when made from Viton (FPM/FKM).
Then it will be about 50 cents more expensive.

Just ask around in the industrial supplies/hydraulic service/agricultural machinery sector .

Okay, that's what I wanted to know before I remove the old ring!!
I assume that the 59 mm is the outer dimension and the 2.5 is the cord diameter.
I'm going to buy some now, possibly silicone ones.

Thank you and best regards.

Generally, silicone is not resistant to fuels, aromatic mineral oils, water vapor (short-term exposure up to 120°C is possible), silicone oils and greases, acids, and alkalis.

Okay, I'll try to find a suitable one.

"Thank you."

You should take another, closer look at that.

Yes, as I understand it now, the 59 mm is the internal dimension.
I haven't been able to find a suitable sealing ring yet.
But it's not urgent yet; it's still running.
If I order one, it will also have a delivery time.
I'll probably stop by the agricultural machinery mechanic's shop sometime.
Thank you again.

Sure, here's the translation:

"Just for information:"
In the field of fluid technology, O-rings are always specified with their inner diameter x cross-section thickness.
surveyed.
Exceptions to this rule are only specially molded seals or profile rings.
which then always receive the specified size at the point of sale.

Just type "ring 59 x 2 5" into the online marketplace and you will find many options.

Okay.
Thank you all again for your help!
Best regards,
