ZD-915 desoldering station not sucking out solder - missing part

[repetto74]

Hi guys,

My ZD-915 desoldering station stopped doing his job and will not sucker solder anymore.
Unfortunately I have figured put what the problem is. After my last gun cleaning I did not pay attention but a rubber sealant on the gun has gone probably into the bin and trashed by mistake 
In the picture attached here  you can see the area where this black rubber sealant is supposed to sit.

Is there any spare of this part i can purchase somewhere or at least search for a substitute?
Many thanks and happy New Year to everybody !

Cool thanks! Looks what I am looking for with some extra spares

3D print ?
Thermoplastic elastomers (TPE) are the best category of filament material for flexible tires. TPE filaments have very similar properties to rubbers which are the most common material for tires. Ninjaflex and Fiberflexare two of the best TPE brands

Thermoplastic Polyurethane (TPU) is a flexible, abrasion resistant thermoplastic which better withstand impacts, also resistant to many chemicals, and exhibits greater rigidity, not to be confused with hardness, also has a smooth finish, and shrinks less than TPE, but TPE burns with a faint aroma whereas TPU burns with an irritating odor.

Are you high on thermoplastic fumes? You can’t use thermoplastic as the hot end gasket!! 

The gasket is in direct contact with the metal tube which is part of the heater assembly and is heated to soldering temperatures, so hotter than the nozzles used to print TPE.

I was indeed thinking to find a standard round rubber that could fit but this part is placed in contact with the pipe connected directly with the heater. Those rubber parts should be also high temperature resistant.

I used the Hakko B5185:

on mine.  It is a replacement glass tube with filter and both seals.

And by the way you can increase the suction force and minimize glogging by putting an Eurocent coin in the middle of the glas tube
and exchange the metal plate at the filter side with a sieve from a perlator...

Nice !
Will try that on mine

Am I correct in assuming that any 1 cent coin would do as long as it is not as big as the inside of the glass tube?  Since percolators are mostly a thing of the past (at least here in the USA) what mesh is that screen?  Or am I wrong and perlator is not a coffee percolator?

My ZD915 just does not have enough suction to clean out a pin (like an IC pin).  I have tried to find a replacement vacuum pump that will fit the ZD915 but more suction and does not cost a fortune!  Has anyone found such a replacement pump source?

Thank you.

  Yes

AFAIK, you are wrong . A perlator is connected to a water tap (at least here in EU) . See photo attached.

Interesting! I’d never heard that term here in Switzerland, either. But we (native English speakers) definitely don’t use that term in English, we just call it an “aerator”.

Now I understand what you were referring to!  Yes I would have known what it was if it had been called an aerator screen or a water tap filter screen.  Thank you.

I understand the why of replacing the metal plate at the back of the chamber in front of the filter with a water tap screen. What is the purpose of the coin in the middle?

To block the solder sucked in and keep the back side with the filter clean.
